Circuit Board Support Member with Dual Clamping Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Circuit boards in computers are prone to loosening or damage during transportation or movement due to inadequate fixation, as they are typically secured by only one end in a slot with a screw.
Innovation Solution
A support member is introduced that clamps the circuit board from both sides, using clamping portions and latching blocks to securely hold the board in place, eliminating the need for screws and facilitating easy assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If only one end of the circuit board is fixed in a slot with a screw, then the device complexity is reduced, but the reliability of the circuit board fixation deteriorates
Solution Approach 1:
The support member is divided into multiple functional segments: a first support portion that contacts the first circuit board, a second support portion that contacts the second circuit board, and a connection portion that links them. This segmentation allows each part to perform its specific function independently, providing comprehensive support while maintaining structural integrity without requiring complex multi-screw fixation.
Solution Approach 2:
The support member acts as an intermediary component between the chassis and the circuit boards. It transfers and distributes mechanical loads from both circuit boards to the chassis, eliminating the need for direct screw fixation of each board while ensuring stable support. The connection portion serves as the intermediary link that coordinates the support forces from both ends.
2Ease of manufacture
If only one end of the circuit board is fixed with a screw, then the ease of manufacture is improved, but the stability of the circuit board deteriorates
Solution Approach 1:
The support member combines multiple support functions into a single integrated component. Instead of requiring separate fixation mechanisms for each circuit board end, the unified support member simultaneously supports both the first and second circuit boards, simplifying the manufacturing process while enhancing overall stability through distributed load bearing.
3Reliability
If a support member with multiple support portions is used, then the reliability of circuit board support is improved, but the device complexity increases
Solution Approach 1:
The support member implements local quality by providing targeted support at specific locations: the first support portion is positioned to contact the first circuit board, the second support portion contacts the second circuit board, and the connection portion links them. Each local region of the support member has optimized geometry and material properties suited to its specific loading conditions, achieving high reliability without requiring complex overall structure.

AI summary
A computer includes a chassis, a circuit board installed in the chassis, and a support member. The support member includes a support portion, a first clamping portion, and a second clamping portion. The first clamping portion and the second clamping portion are respectively located at two ends of the support portion. The first clamping portion is configured to clamp the circuit board. The second clamping portion is configured to clamp the chassis.
