Definitions

  • Shelving systems are commonly used for the efficient display or storage of consumer goods and other items.
  • shelving systems In their most basic form, shelving systems use fixed (non-adjustable) shelves. Such systems necessarily are designed with sufficient spacing between shelves to accommodate the largest or tallest object expected to be stored therein. A considerable storage volume can be wasted if such a system is used to store items smaller than those considered in establishing the design. Such wasted storage volume could be reduced by reducing the spacing between shelves, but only at the expense of no longer providing capacity to store larger items.
  • Manually adjustable shelving systems can decrease these inefficiencies by allowing the user to set shelf spacing as necessary for a particular application and to adjust the shelf spacing as needs change.
  • manually adjustable systems typically require that items borne on a shelf be removed from the shelf before adjustments can be made.
  • Power operated shelving systems can overcome this problem by allowing the user to adjust shelf spacing on demand, without first clearing a shelf of its contents.
  • power operated shelving systems using conventional mechanical switch control interfaces also have limitations.
  • mechanical switches typically include internal moving parts which are at least somewhat exposed to the environment. As such, contaminants, such as dirt or moisture, can enter the switch mechanism and increase the risk of malfunction or the severity of mechanical wear. Also, the discontinuities and crevices associated with mechanical switches can make such switches and the areas around them difficult to clean.
  • mechanical switches typically have large profiles, often making it difficult to integrate them into a shelving system where space is limited.
  • mechanical switches typically require a dedicated switch panel which might not easily be integrated into a shelving unit and might even need to be mounted remotely from the shelving unit.
  • mechanical switches generally can control only a single function, a system wherein many functions need to be controlled requires the use of a like number of such switches.
  • the use of mechanical switches is disadvantageous in shelving systems wherein space conservation is an important consideration.
  • Conventional shelving systems include numerous other disadvantages. For example, the depth of the shelves in conventional refrigerators and the disparate sizes of products stored thereon can make it cumbersome to take inventory of items in a refrigerator. This task is further complicated by the fact that conventional refrigerators typically use opaque doors, making it impossible to see the contents of the refrigerator without opening the door. As such, taking inventory requires opening the door, a practice that is not only inconvenient, but energy inefficient as well.
  • WO 03/043464 describes an intelligent shelving system that uses touch switch sensors to operate power-operated adjustable shelves, to control shelf motion, to monitor encroachment of shelved items on shelves, to detect spills, and to control other related devices and functions.
  • a shelving system according to the present invention can include power-operated shelf adjustment and can incorporate spill detection, adaptive and intelligent operator/equipment interfacing, encapsulated lighting and other features as further described below.
  • touch input devices that respond to a user's touch or proximity for control input.
  • touch input devices can include, for example, capacitive switches, infra-red touch sensors, and field effect sensors. Touch input devices can minimize many of the problems associated with mechanical switches and generally are more reliable, ergonomic and aesthetic. Also, a single touch input device can be more easily configured to selectively control several different functions.
  • Touch sensors are solid state devices that respond to a user's touch or proximity.
  • Touch sensors commonly include electrodes and electronic components mounted on a substrate. This substrate might have a user-accessible operative touch surface. Preferably, this touch surface is on the side of the substrate opposite the side that bears the touch sensor's electrodes and electronic components. In alternate embodiments, the operative touch surface can be on another substrate that is attached to or otherwise associated with the substrate bearing the touch sensor components. In either embodiment, a signal is supplied to the electrode(s), thus generating an electric field about the operative touch surface. When the electric field is disturbed by a user's touch or proximity, the touch sensor circuitry generates a control signal that can be used to control the operation of a light, motor or other end device.
  • Touch sensors overcome many disadvantages inherent to mechanical switches. For example, because a touch sensor's operative touch surface can be a non-perforated substrate, the touch sensor is much less susceptible to damage due to liquids and other foreign matter. Because a touch sensor has no moving parts, it is much less prone to wearing out. Because a touch sensor and its substrate can be (but need not be) substantially planar, problems related to the large profile of mechanical switches can be avoided, thus removing the design limitations that relatively large profile mechanical switches impart on the design of shelving systems and the like.
  • touch switch controlled, power-operated shelves is particularly advantageous because touch switch assemblies have a low profile and, as discussed above, can prevent malfunctions owing to moisture and contaminants associated with mechanical switches that might otherwise be used in this application.
  • the potential for malfunction of a mechanical switch due to contamination is heightened in this application because refrigerator shelves often bear liquids and foodstuffs that are prone to being spilled onto shelves and that can then drip through or around such shelves.
  • Mechanical switches are particularly susceptible to short circuit failure under these conditions. Such malfunctions can be prevented by using touch sensors having a non-perforated touch surface substrate that can prevent liquids from reaching the touch sensor's electronic components.
  • FIGS. 1-4 depict an embodiment of the present invention involving a refrigerator having power-operated shelves controlled by touch sensors.
  • FIG. 1 shows a refrigerator 100 including three power-operated shelves 10, 11 and 12 mounted on movable brackets 40, which are, in turn, connected to a suitable drive mechanism (not shown). Any suitable type of power or drive mechanism, e.g., electric, hydraulic, or pneumatic, can be used.
  • the drive mechanism can carry brackets 40 and, in turn, shelves 10, 11 and 12 vertically up or down as desired, and can support shelves 10, 11 and 12 in a stationary position.
  • shelves can be movably mounted in any number of configurations as required by the particular application. Expected shelf load and dimensions and cost considerations, as well as the configuration of refrigerator 100 itself, dictate which mounting configuration or drive mechanism would be most advantageous. Shelving systems according to the present invention can include conventional fixed or manually adjustable shelves in addition to one or more power operated shelves, as depicted in FIG. 1 .
  • each hard key 30 includes an operative touch surface which can be touched by a user to actuate an underlying touch sensor.
  • the touch sensor underlying a hard key 30 when triggered by user input, generates a control signal that controls a specific device in a predetermined manner.
  • a hard key 30 might be used to turn on a light on and off.
  • a first hard key 30 might be used to cause a shelf to be raised, while another might be used to cause raise a shelf to be lowered.
  • shelf 11 also includes "soft key" 31, each of which also includes an operative touch surface having an underlying touch sensor.
  • a soft key 31 does not necessarily control a specific device in a predetermined manner. Instead, a soft key 31 can be used to execute various control functions, for example, a function identified by a message prompt on an input/output display 233.
  • Display 233 can display any variety of message prompts corresponding to functions that might be applicable to a particular system. A user desiring to execute the function corresponding to the message displayed on display 233 can do so by simply touching the appropriate soft key 31.
  • soft key 31 could serve as a confirmation key which could be used to execute a function corresponding to the message prompt when validation of a previously selected input might be required. For example, if a user tries to adjust a shelf outside predetermined limits, such as above a maximum height or to less than a minimum distance relative to another shelf, a safety mechanism might interrupt the execution of the input. In these situations input/output display 233 might prompt "Continue to raise this shelf or simply "Continue.” The user would touch soft key 31 to continue to raise the shelf.
  • soft keys are reconfigurable and can control functions that are dependent on the state of the system and the corresponding prompt of input/output display 233.
  • shelf 13 includes frame 22 and load surface 20.
  • Load surface 20 can be made of glass, plastic or any other material suitable for the particular application.
  • Shelf 13 also includes control panel 21 having hard keys 30, 33 and 34.
  • frame 22 and load surface 20 would be fabricated as separate pieces and then joined mechanically or using adhesives.
  • frame 22 could also be molded or formed onto load surface 20, with or without adhesives.
  • control panel 21 could be an integral part of frame 22 or load surface 20, or it could be a separate subassembly.
  • touch sensors underlying hard keys 30, 33 and 34 could be integrated into control panel 21 according to the disclosure of U.S. Provisional Patent Application Serial No. 60/341,550 , which teaches blinkegration of touch sensors and touch switch assemblies into other components, for example, a refrigerator shelf, refrigerator door or other refrigerator component. Touch sensors could also be applied to control panel 21 in a conventional manner.
  • User input to the hard keys of FIG. 2A can trigger the vertical movement of shelf 13 or cause some other response.
  • user input to hard key 33 can trigger the upward movement of shelf 13
  • user input to hard key 34 can trigger the downward movement of shelf 13.
  • User input to hard key 30 can trigger any other response advantageous for the particular application.
  • user input to hard key 30 could trigger a light, for example, a light pipe, that could illuminate load surface 20 of shelf 13 to facilitate location of items on shelf 13.
  • load surface 20 itself could be a light pipe or other lighting device.
  • User input to hard key 30 could also trigger a lock/unlock response that either allows or prohibits movement of shelf 13 until a user has touched hard key 30.
  • lock key 35 serves the locking function, allowing hard key 30 to serve some other function, such as switching a light on or off.
  • FIGS. 2B and 3A-3C depict shelf 11 of FIG. 1 in greater detail.
  • shelf 11 is shown including wiring harness 234, which can provide power to the display board 133 of input/output display 233, borne on substrate 132, and can carry signals to and from the touch sensors underlying hard and soft keys 30 and 31.
  • Wiring harness 234 could also communicate a response output from the touch sensors of display board 133 in applications where the touch sensors do not include integrated control circuits proximate their electrodes.
  • Wiring harness 234 can be molded directly into frame 22.
  • Wiring harness 234 could also be formed by applying conductors (not shown) along the edge of load surface 20.
  • the conductors could be applied using various methods such as screen printing of silver or copper-based frits or epoxies, electroplating or by any other suitable method.
  • shelf 11 can be configured so that frame 22 protects the conductors from the environment of the refrigerator.
  • wiring harness 234 can be completely eliminated and the touch switch-controlled device can receive touch sensor inputs via a radio frequency transmitter-receiver system.
  • the radio transmitters associated with the touch sensors of the shelf could also relay important system information, such as information regarding the relative positions of the shelves in the system.
  • Input/output display 233 can also be configured to present device information to a user, either simply as information, such as temperature or humidity levels, or as part of a message prompt soliciting a response.
  • Display board 133 is mounted on display board substrate 132 which, in turn, is affixed to control panel 21 using adhesive layer 134.
  • Display board 133 displays messages and other information to the user.
  • Display board 133 can be of any suitable construction depending on the requirements of the application. For instance, display board 133 could be a vacuum fluorescent display, liquid crystal display, electroluminescent display, electrophoretic display, polymer display, light emitting diode, or any other type display.
  • the touch switch electrical components are disposed on touch sensor substrate 36, which also defines operative touch surfaces 38.
  • Substrate 36 is sufficiently transparent to allow a user to view messages on display board 133.
  • the touch switch electrical components include electrode 31, integrated control circuit 32 and circuit trace 39.
  • electrode 31 preferably is transparent to allow the message prompts of display board 133 to reach the user.
  • Other touch sensor configurations and types are also suitable for use in connection with the present invention.
  • control circuit 32 could be located remote from transparent electrode 31.
  • Other types of touch sensors appropriate for use in connection with the present invention include, but are not limited to, electric field, capacitive, infra-red, differential touch sensors, or touch sensors and touch switch assemblies according to the disclosure of U.S. Provisional Patent Application Serial No. 60/334,040 .
  • Touch sensor substrate 36 can be decorated with decoration 136.
  • Decoration 136 can be applied using, for example, the disclosure of U.S. Provisional Patent Application Serial No. 60/341,551 and can be transparent and made of glass, plastic or other suitable material.
  • control panel 21 of shelf 12 includes hard keys 30, 33 and 34 and lock key 35 as well.
  • Display 233 could be a separate assembly including a housing or other structure or could be integrated with control panel 21 of shelf 12 as shown in FIGS. 3A-3B .
  • the components of display boards 133 and of touch sensors or touch switch assemblies can be either rigid or flexible, depending on the requirements of the application.
  • any of the touch switches corresponding to operative touch surfaces 38 can be configured as either a hard or a soft key.
  • the touch sensors and operative touch surfaces labeled "1" - “3” could be configured as soft keys which could be used to effect control of whatever function the soft key represents at any given time.
  • This function typically would be represented on the portion of display board 133 underlying a particular soft key.
  • display board 133 might prompt "RAISE SHELF?".
  • the user could select the touch surface 38 labeled "Y” to make the system carry out the prompted action (in this example, raising the shelf), select the touch surface 38 labeled “N” to cancel the prompted action, or select the touch surface labeled "?” to cause an information message to be displayed on display board 133.
  • Input/output display 233 can also include hard key touch sensors that can be configured to induce the vertical movement of shelf 12, or any other desired response, according to the particular design or application requirements. As shown in FIG. 3A , not all areas of display 233 need include operative touch surfaces. However, in other embodiments, it might be preferred that all areas of display 233 include operative touch surfaces.
  • the touch sensor of lock key 35 is shown as including electrode 130, integrated control circuit 32, and circuit trace 39 disposed on touch sensor substrate 232, which is integrated into control panel 21. Since lock key 35 is shown embedded in the material of control panel 21, electrode 130 need not be a transparent electrode 31.
  • Hard key 30 can have a similar touch sensor configuration and can conform to the surface of control panel 21, for example, according to the disclosure of U.S.
  • Touch sensor substrate 332 bearing electrode 130 preferably is flexible to allow for easy conformity with the curvature of hard key 30, which is defined by the curvature of the corresponding portion of control panel 21.
  • the particular configuration of display 233 and control panel 21 of shelf 12 is a matter of design choice.
