Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding frames for connector modules are difficult to assemble and disassemble, especially when multiple modules are used, and they often require specialized tools, limiting versatility and compatibility with different latching geometries.
Innovation Solution
A telescoping, two-part holding frame with a sliding bearing arrangement allows for easy assembly and secure locking of connector modules, accommodating both internally and externally latched modules, with resilient latching arms and tool-free locking devices for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional rigid holding frame is used, then mechanical stability is improved, but assembly and disassembly become difficult and require special tools
Solution Approach 1:
The holding frame transitions from a rigid static structure to a dynamic structure with telescopic sides that can move relative to each other. The sides are connected via sliding bearings, allowing the frame to expand during assembly and contract during operation, enabling easy module installation while maintaining mechanical stability
Solution Approach 2:
The holding frame is divided into multiple separable sides (at least two opposite sides) that can move independently. This segmentation allows the frame to be opened for assembly and closed for operation, eliminating the need for special disassembly tools while maintaining structural integrity
2Reliability
If holding projections protrude from side walls to secure modules, then module retention is improved, but the clear width between opposite wall parts decreases
Solution Approach 1:
The side walls are designed to move telescopically, changing the clear width dynamically. During assembly, the frame is expanded to provide sufficient clearance for module insertion. During operation, the frame contracts to allow holding projections to effectively retain modules, thus resolving the width constraint
Solution Approach 2:
The frame is pre-expanded before module insertion to ensure adequate clear width. After modules are positioned, the frame is contracted to engage the holding projections with the modules, ensuring secure retention without requiring permanent wide spacing
3Adaptability or versatility
If the holding frame is designed to accommodate multiple module types, then versatility is improved, but device complexity increases
Solution Approach 1:
The holding frame is designed with universal holding means (openings and projections) that can accommodate different module types through standardized interaction mechanisms. The telescopic side structure provides a flexible platform that can adapt to various module configurations without requiring multiple specialized frames
Solution Approach 2:
The frame's segmented side design allows independent positioning and configuration of holding means on each side, enabling adaptation to different module types while maintaining a relatively simple overall structure. Each side can be independently adjusted to accommodate specific module requirements
