Multiple Board Standoff With Keyhole Slots For PCB Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multiple board standoff solutions for printed circuit boards (PCBs) are costly, difficult to assemble, and inefficient in terms of space usage, requiring multiple components and creating structural weaknesses.
Innovation Solution
A multiple board standoff system featuring a longitudinal body with major and minor diameter portions and abutment surfaces, where the minor diameter portions are inserted into keyhole slots on the PCBs, allowing for easy assembly and secure locking by rotating the standoff, reducing the need for multiple components and minimizing space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple standoffs are used to connect a plurality of PCBs, then the PCBs can be supported and insulated, but the assembly becomes difficult and expensive
Solution Approach 1:
The patent combines multiple standoff functions into a single integrated component. The multiple board standoff includes a body with multiple legs that can simultaneously connect multiple PCBs, eliminating the need for multiple separate standoffs. This merging reduces assembly complexity while maintaining the support and insulation functions.
Solution Approach 2:
The multiple board standoff is designed to perform multiple functions: it supports multiple PCBs simultaneously, provides insulation between boards, and enables easy assembly through its integrated structure. The single component serves as both a mechanical support and an electrical insulator for multiple boards, reducing the total number of components needed.
2Reliability
If multiple standoffs are staggered to connect PCBs, then the PCBs can be interconnected, but space is consumed and structural weaknesses are created
Solution Approach 1:
The patent merges multiple connection points into a single integrated standoff structure. The body with multiple legs provides interconnection for multiple PCBs from a single location, reducing the total space required compared to staggered individual standoffs while maintaining reliable interconnection.
3Reliability
If multiple standoffs are used to connect PCBs, then the PCBs can be secured at proper spacing, but the cost increases
Solution Approach 1:
The patent combines multiple standoff components into a single manufactured part. The integrated structure with multiple legs is produced as one piece, reducing the total component count and assembly steps, which lowers manufacturing costs while maintaining proper PCB spacing and security.
4Device complexity
If traditional standoffs are used, then simple structure is maintained, but assembly is difficult and time-consuming
Solution Approach 1:
The patent merges multiple assembly operations into a single action. The integrated multiple board standoff can be installed in one piece, securing multiple PCBs simultaneously, which dramatically increases assembly speed compared to installing multiple individual standoffs separately.

AI summary
A multiple board standoff for interconnecting a plurality of electronic boards, such as printed circuit boards, having at least one keyhole slot. The standoff comprises a plurality of major diameter portions, a plurality of minor diameter portions each disposed between two of the plurality of major diameter portions, and a plurality of abutment surfaces each transversely extending from one of the major diameter portions to one of the minor diameter portions. At least one of the minor diameter portions is configured to be inserted into the keyhole slot when the standoff is in a first orientation with respect to the electronic board and being retained within the keyhole slot when the standoff is in a second orientation with respect to the electronic board.
