Resilient Positioning Column for Circuit Board Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Assembling circuit board components can result in curvature or bending, leading to potential damage due to fixation forces from housings, which may cause harm to the circuit board and connected components like surface mount devices (SMDs).
Innovation Solution
The use of a positioning column integrated with a housing member and resilient members to absorb and compensate for forces applied to the circuit board, featuring a flared portion for insertion through the board and radial flanges to engage it securely, thereby minimizing damage from housing forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the housing fixes the circuit board in place to prevent rattling, then the stability of the circuit board is improved, but the fixation forces may damage the circuit board and connected components
Solution Approach 1:
The patent introduces resilient members (such as resilient rings or elastomeric elements) positioned between the housing and the circuit board. These resilient members are pre-installed to cushion and absorb fixation forces before they reach the circuit board, preventing damage while maintaining stability. The resilient members deform under compression to accommodate the circuit board without applying excessive fixed forces.
2Strength
If the housing applies increased forces to the circuit board due to manufacturing tolerances, then the fixation strength is improved, but the circuit board and connected components may be damaged
Solution Approach 1:
The patent changes the mechanical parameter of force transmission by introducing compliant/resilient elements between the rigid housing and the circuit board. These elements transform the rigid force transmission into a compliant interaction, allowing the housing to accommodate manufacturing tolerances while limiting the maximum force applied to the circuit board to safe levels.
3Manufacturing precision
If the positioning column is rigidly connected to the housing, then the positioning precision is improved, but the circuit board may be damaged by fixed forces
Solution Approach 1:
The patent introduces resilient members as intermediary elements between the positioning column and the housing. These intermediaries maintain the positioning function while decoupling the rigid force transmission path, allowing the positioning column to provide precise positioning without transmitting damaging fixed forces to the circuit board.
