Hinged Cover Plate for Electronic Device Assembly Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience and increased costs when assembling or disassembling electronic devices due to the removable back plate often getting lost, necessitating the purchase of additional plates to cover the assembling opening.
Innovation Solution
A clamshell structure featuring a window-type frame with a pivoting cover plate that can be opened and fixed using a rubber bulk and pillar plug mechanism, allowing the cover plate to remain in an open state without removal from the back casing, thereby exposing the assembling opening for easy access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a removable back plate is used to cover the assembling opening, then the assembling opening can be covered when not in use, but the back plate may be lost during assembling or disassembling operations, requiring additional plates and increasing cost
Solution Approach 1:
The back plate is transformed from a statically removable component to a dynamically hinged component that can rotate between closed and open positions. The pivot connection allows the plate to swing open during assembly operations and automatically return to closed position, eliminating the need to completely remove and store the plate.
Solution Approach 2:
The back plate is divided into functional segments: a main plate body for covering the opening, a pivot connection for rotational movement, and a return mechanism for automatic positioning. This segmentation allows independent optimization of each component's function.
2Stability of the object's composition
If the back plate is firmly fixed to the back casing, then the cover remains secure, but the user cannot easily access the assembling opening for assembling or disassembling transmission interface cards
Solution Approach 1:
The hinge connection provides dynamic stability - the plate remains securely attached to the casing body through the pivot point while allowing controlled rotational movement. This eliminates the need to completely detach the plate for access, maintaining both security and accessibility.
Solution Approach 2:
The pivot connection acts as an intermediary mechanism between the back casing and the cover plate, providing a flexible connection that accommodates both stable positioning and controlled movement requirements.
3Ease of operation
If a hinged cover plate structure is implemented, then the cover plate can remain attached during assembly operations, but additional components (pivot, fixing members) are added to the structure
Solution Approach 1:
The hinged cover plate system is segmented into modular components: the back casing body, the pivot connection, the cover plate, and simple fixing members. This modular segmentation allows each component to be independently manufactured and assembled, reducing overall system complexity despite the added functionality.

AI summary
A clamshell structure for an electronic device includes a window-type frame, a cover plate and a pivot. The window-type frame has an opening, and includes a first pivoting portion and a first fixing member. The first pivoting portion is near the opening. The first fixing member is disposed on a cover fixing area of the window-type frame. The cover plate includes a clamshell body, a second pivoting portion and a second fixing member. The clamshell body is used to cover the opening. The second pivoting portion is disposed on the opening. The second fixing member is disposed on an open side of the clamshell body. The pivot is pivoted through the first pivoting portion and the second pivoting portion. When the clamshell is opened, an electronic component is mounted into or dismounted from the opening for assembling or disassembling.
