Cantilever Standoff for Multi-Board Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing standoff systems for circuit boards require multiple screws or bolts for assembly and disassembly, leading to inconvenience and increased costs when securing multiple boards, as they often result in lost components and necessitate specialized tools.
Innovation Solution
A cantilever-type standoff system that uses a single unit with cantilevers, blocking plates, and bumps to secure multiple substances without screws or bolts, allowing for simultaneous securing and easy assembly/disassembly through co-rotation of cantilevers and elastic engagement of bumps with corresponding holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple screws or bolts are used to secure circuit boards, then the securing reliability is improved, but the device complexity and loss of components increase
Solution Approach 1:
The patent combines multiple securing functions into a single integrated standoff structure. The cantilever-type standoff integrates the support function, the clamping function through elastic cantilevers, and the positioning function through bumps, replacing what would traditionally require multiple separate screws or bolts to achieve the same securing effect.
Solution Approach 2:
The single standoff structure performs multiple functions simultaneously: it provides mechanical support, secures the circuit board through elastic clamping, and ensures precise positioning through integrated bumps. This multi-functional design eliminates the need for separate fastening components.
2Strength
If traditional screws or bolts are used for assembly, then the securing strength is improved, but the ease of operation deteriorates due to tool requirements and component loss
Solution Approach 1:
The elastic cantilevers automatically clamp the circuit board when installed and can be easily released by applying downward pressure. The structure is self-contained with no external tools required, and the components cannot be lost as everything is integrated into the single standoff body.
Solution Approach 2:
The elastic cantilevers provide dynamic clamping action that automatically adjusts to the circuit board thickness and maintains constant securing force. The flexible design allows easy installation and removal while maintaining strong securing during operation.
3Adaptability or versatility
If additional standoffs are added to secure more than three circuit boards, then the securing capability is improved, but the productivity and cost increase
Solution Approach 1:
The single standoff structure is designed to secure multiple circuit boards simultaneously through its array of elastic cantilevers and bumps. The standardized design allows the same component to handle various configurations, eliminating the need for different types of fasteners for different numbers of boards.
Solution Approach 2:
The patent merges the function of multiple separate standoffs into a single integrated unit. What would traditionally require three or more individual standoffs and fastening operations is achieved with one component, reducing assembly steps and improving productivity.
