Chassis Member with Integral Hinge Shaft Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing chassis designs for electronic devices, such as laptop PCs, face challenges in miniaturization and aesthetic improvement due to the intrusion of mounting screws and plates for hinge devices, which increase the bezel width and hinder the integration of displays closer to the chassis edges.
Innovation Solution
A chassis member featuring a laminated prepreg frame with an integral shaft supporting portion, including a projecting boss section and reinforcing ring, allows for press-fitting of hinge shafts without screws, enabling a more compact and aesthetically pleasing design by minimizing bezel width and enhancing structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a resin frame with mounting plate and screw is used to secure the hinge device, then the hinge device can be firmly fixed, but the mounting plate and screw significantly intrude into the display chassis, increasing the bezel width and hindering miniaturization
Solution Approach 1:
The invention extracts and eliminates the mounting plate and screw components from the traditional hinge fixation system. Instead of using a resin frame with separate mounting elements, the chassis member integrates the hinge shaft insertion hole directly into the frame structure, removing the intrusive mounting plate and screw while maintaining secure hinge fixation.
Solution Approach 2:
The invention merges the hinge shaft support function directly into the chassis frame structure. The insertion hole for the hinge shaft is formed integrally with the frame, combining what were previously separate components (frame and mounting structure) into a unified integrated structure that eliminates the need for additional mounting elements.
2Area of stationary object
If the display is positioned closer to the chassis edge, then the quality of appearance and miniaturization are improved, but the hinge device cannot be securely mounted without sufficient space for mounting plate and screw
Solution Approach 1:
The invention removes the mounting plate and screw components that previously required significant space for hinge device mounting. By eliminating these intrusive elements, the design allows the display to be positioned closer to the chassis edge while still providing secure hinge fixation through the integrated insertion hole structure.
Solution Approach 2:
The invention introduces an insertion hole as an intermediary structure that directly receives the hinge shaft. This intermediary feature eliminates the need for the traditional mounting plate and screw system, providing a compact yet reliable mounting solution that enables smaller bezel widths.
3Reliability
If traditional resin frame with mounting plate is used, then hinge device can be screwed in, but the structure becomes complex and space-consuming, preventing display close integration
Solution Approach 1:
The invention merges the hinge shaft support function directly into the chassis frame structure. The insertion hole for the hinge shaft is formed integrally with the frame, combining what were previously separate components (frame and mounting structure) into a unified integrated structure that simplifies the overall design and reduces complexity.
Solution Approach 2:
The invention extracts and eliminates the mounting plate and screw components from the traditional hinge fixation system. By removing these separate mounting elements and integrating the fixation function directly into the frame, the design significantly reduces structural complexity while maintaining reliable hinge device fixation.

AI summary
A chassis member is used for an electronic device, including a face plate, and a frame to be fixed to one face of the face plate and provided along at least one side of a peripheral edge of the one face. The frame is formed by laminating a plurality of layers of a prepreg containing reinforced fiber impregnated with resin. The frame has a frame body to be fixed to the one face, and a shaft supporting portion formed integrally with the frame body and formed with an insertion hole for press-fitting a shaft-like member.
