Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Circuit boards are at risk of damage during the process of removing components due to inadequate holding mechanisms, which can lead to physical stress and potential destruction.
Innovation Solution
A fixing apparatus comprising a cover plate, base, connecting assembly, and latching assembly that cooperatively clamp and secure the circuit board in place, using a recess to prevent squeezing and positioning blocks to maintain alignment, along with a cushion member to absorb pressure and a suction device to adhere the board firmly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a simple holding mechanism is used, then the device complexity is reduced, but the circuit board is at risk of damage during component removal
Solution Approach 1:
The holding mechanism is divided into multiple independent components: a base plate with positioning blocks, a cover plate with recess, and connecting/latching assemblies. This segmentation allows each component to perform a specific function (positioning, clamping, protecting) while maintaining overall system reliability without excessive complexity
Solution Approach 2:
The recess in the cover plate is designed to accommodate the circuit board with predetermined cushioning, preventing direct contact between the circuit board and the rigid cover plate. This beforehand cushioning protects the circuit board from damage during component removal while maintaining a relatively simple overall structure
2Reliability
If a rigid clamping mechanism is used, then the circuit board is held securely, but the circuit board may be squeezed or damaged
Solution Approach 1:
The recess in the cover plate creates a cushioning space between the circuit board and the rigid cover plate surface. This beforehand cushioning design ensures that when the cover plate is closed, the circuit board is held securely without being squeezed or damaged by direct rigid contact
Solution Approach 2:
The cover plate acts as a flexible element that can deform slightly under compression, providing adaptive cushioning to the circuit board. This flexible design allows secure holding while distributing pressure evenly to prevent localized stress concentration that could damage the circuit board
3Reliability
If no positioning mechanism is used, then the device complexity is reduced, but the circuit board may deviate during component removal
Solution Approach 1:
The positioning function is segmented into multiple positioning blocks arranged at different locations on the base plate. Each positioning block independently constrains the circuit board in a specific direction, achieving accurate positioning through simple, discrete elements rather than a complex integrated mechanism
Solution Approach 2:
The positioning blocks are designed to automatically engage with the circuit board edges when the cover plate is closed, providing self-aligning positioning without requiring complex adjustment mechanisms. The circuit board itself serves as the reference for positioning, eliminating the need for external positioning devices

AI summary
A fixing apparatus for holding a circuit board in place includes a cover plate, a base for supporting the circuit board thereon, a connecting assembly for hinge-coupling a first end of the cover plate to the base, and a latching assembly for latching a second end of the cover plate to the base. The circuit board is held in place between the base and the cover plate.
