Solution Overview
Problem
Existing methods for securing computing modules to circuit boards in computing devices often require fasteners and specialized tools, which can be lost, incorrectly used, or improperly torqued, leading to damage and connectivity issues.
Innovation Solution
A toolless, removable locking device with a shelf and stay mechanism that secures computing modules to circuit boards, allowing easy installation and removal without fasteners or tools, minimizing stress and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fasteners and specialized tools are used to secure computing modules, then the connection strength and reliability are improved, but the ease of operation and risk of damage increase
Solution Approach 1:
The locking device is designed to be self-operating without requiring external tools. The user simply presses the computing module into the socket, and the locking device automatically engages through its spring-loaded mechanism, eliminating the need for specialized installation tools and reducing operational complexity while maintaining secure connection.
Solution Approach 2:
The patent replaces traditional screw-based mechanical fastening systems with a spring-loaded elastic member mechanism. This substitution eliminates the need for torque-controlled fasteners and specialized tools, allowing simple press-fit installation while maintaining reliable mechanical and electrical connections through the elastic locking action.
2Strength
If fasteners are used to secure computing modules, then the connection strength is improved, but the risk of loss and misplacement increases
Solution Approach 1:
The locking device integrates the retention function directly into the socket structure itself, merging the fastening mechanism with the electrical connector housing. The spring-loaded elastic members are built-in components that permanently reside in the socket, eliminating separate fasteners that could be lost during assembly or disassembly operations.
Solution Approach 2:
The built-in spring-loaded mechanism provides automatic retention without requiring external fasteners. The elastic members self-engage when the computing module is inserted and self-disengage when removal is initiated, providing continuous secure holding without the risk of losing separate fastening components.
3Reliability
If improper torque is applied to fasteners, then the connection may be insecure, but excessive torque causes damage
Solution Approach 1:
The patent replaces torque-dependent screw fastening with a spring-loaded elastic member system that provides automatic force regulation. The elastic members exert consistent retaining force through their spring characteristics, eliminating the risk of over-torquing or under-torquing that plagues traditional mechanical fastening systems.
Solution Approach 2:
The spring-loaded elastic members provide built-in compliance and cushioning that prevents excessive force transmission to the computing module components. The elastic nature of the retaining members absorbs force variations and prevents damage from improper installation forces, protecting sensitive electronic components from mechanical stress.
