Description of embodiments
With reference to an example shown in Figure 1 , a housing of a portable wireless communication device comprises a first housing member 100 and a second housing member 102 which joined together result in the housing trated from the downward direction with respect to the illustration shown in Figure 1.
A housing of a portable wireless communication device is typically a protective cover designed to contain or support mechanical and/or electric components of the portable wireless communication device. The housing 200 may further comprise other parts, such as those that close the housing, not shown in Figure 2.
The portable wireless communication device may be a mobile phone, a PDA (Personal Digital Assistant) or another handheld device having a capability of communicating wirelessly. The invention is not, however, restricted to the given examples, but may be applied to any portable wireless communication device.
The first housing member 100 typically comprises at least one first housing wall 104, 106, 108, 1 10. The first housing wall 104 to 1 10 may be made of plastic or metal, for example.
In an embodiment of the invention, the first housing member 100 is manufactured with a deep-drawing technique. In another embodiment of the invention, the first housing member 100 is manufactured from metal or plastic with a pressure casting technique. In an embodiment of the invention, the wall thickness of the first housing member 100 is between 0.1 mm and 0.5 mm. In this case, the second housing member 102 is typically made of metal.
If the housing material is plastic, the wall thickness may vary from 0.4 mm to 2.0 mm. The invention is not, however, restricted to the given wall thickness figures.
The second housing member 102 typically comprises at least one second housing wall 1 14, 1 16, 1 18, 120. The second housing wall 1 14 to 120 may be made of plastic or metal, for example.
In an embodiment of the invention, the second housing member 102 is manufactured with a deep-drawing technique. In another embodiment of the invention, the second housing member 102 is manufactured from metal or plastic a with pressure casting technique.
In an embodiment of the invention, the wall thickness of the second housing member 102 is between 0.1 mm and 0.5 mm. In this case, the second housing member 102 is typically made of metal. If the housing material is plastic, the wall thickness may vary from 0.4 mm to 2.0 mm. The invention is not, however, restricted to the given wall thickness figures.
The first housing member 100 and the second housing member 102 are profiled so that when joined together, a hollow beam structure 202, 204, 206, 208 is formed in the housing 200. It is also possible to join together more than two members to form the hollow beam structure 202, 204, 206, 208.
The hollow beam structure 202 to 208 rigidifies the housing 200, thus reducing the need for other supporting structures, such as bottom plates, in the portable wireless communication device.
In an embodiment of the invention, the first housing member 100 and the second housing member 102 form a nested layer structure. In the nested layer structure, the first housing member 100 typically covers the second housing member 102 when viewed from the outside of the housing. With reference to Figure 3, an example of the profile of the hollow beam structure 300 is shown. The profile may present, for example, the cross- section 210 of the hollow beam structure 202.
In an embodiment of the invention, the hollow beam structure 300 is a box-beam structure. The box-beam structure may be obtained with an L- shaped first housing member 302 and an L-shaped second housing member 304. The L-shaped profile members 302, 304 may be joined so that a hollow chamber 306 is formed between the profile members 302, 204. The hollow chamber 306 may longitudinally extend throughout the hollow beam structure 202. The hollow beam structure 300 may also contain more than one chamber. The extensions of the L-shaped profile members 302, 304 may be turned parallel with respect to each other so as to enable thin junction sections 308, 310 to be formed between the first housing member 302 and the second housing member 304.
In an embodiment of the invention, the first housing member 100 and the second housing member 102 are joined together by using laser techniques, welding, ultrasound welding and/or adhesive.
In an embodiment of the invention of the invention, the hollow beam structure 202 to 208 forms at least a portion of the outer frame of the portable wireless communication device. In such a case, the first housing member 100 may comprise a first aperture 1 12 and the second housing member 102 may comprise a second aperture 122 for providing a follow-through for functional units, such as a user interface, of the portable wireless device.
In an embodiment of the invention, the hollow beam structure 202 to 208 provides a self-supported frame for the portable wireless communication device. The self-supported frame may be obtained by forming the entire outer frame from the hollow beam structure 202 to 208 and by introducing connecting means 212 for connecting electronics and mechanics to the self-supported frame.
In an embodiment exemplified in Figure 4, the first housing member 400 forms at least a part of the cover of the portable wireless communication device, and the second housing member 402 is joined to the inner surface of the first housing member 400. The inner surface is the surface of the first housing member 400 that faces towards the inside of the portable wireless communication device. As a result, a bi-layer housing exemplified in Figure 5 is ob- tained. The housing 500 may comprise apertures 506 for a display and a keypad.
The cover may be a front cover, a back cover or both the front cover and the back cover.
A housing similar to that shown in Figure 5 may be obtained by join- ing the first housing member 400 of Figure 4 to the second housing member 102 of Figure 1. In such a case, the housing includes both bi-layer and monolayer parts.
Figure 6 illustrates an example of a profile 600 of a cross section 502 of the housing 500. The first housing member 602 provides the cover for the housing, while the second housing member 604 provides a supporting structure and defines the hollow chambers 606A, 606B in the sides of the housing with the first housing member 602. Figure 6 further illustrates mechanics and/or electronics 608 attached to the housing.
Figure 7 illustrates an example of a profile 700 of a cross section 504 of the housing 500. In this view, the hollow chambers 702A, 702B are located in the ends of the housing.
With references to Figures 8 and 9, embodiments of methodology of manufacturing the housing are illustrated with flow charts.
In 800, the method starts. In 802, a hollow beam structure 300 is formed in the housing by joining together a first housing member 100 and a second housing member 102, which define a hollow chamber 306 of the hollow beam structure 300. The first housing member 100 and the second housing member 102 may be joined together by using laser techniques, welding, ultrasound welding, screws, rivets, snap-in-joints and/or adhesive. In an embodiment of the invention, the hollow beam structure 300 is formed in 802 as a nested layer structure from the first housing member 100 and the second housing member 102.
In 804, at least a part of the outer frame of the portable wireless communication device is formed from the hollow beam structure 202 to 208. In an embodiment of the invention, the hollow beam structure 202 to 208 surrounds the housing 200.
In 806, the method ends.
In 900, the method starts.
In 902, at least a part of the cover of the portable wireless commu- nication device is formed from the first housing member 100.
In 904, the hollow beam structure 202 to 208 is formed by joining the second housing member 102 to the inner surface of the first housing member 100.
