Modular Fixed-Pole Contact Insert for Flexible Connector Layouts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fixed-pole contact inserts are limited in their application flexibility and inflexible due to the fixed integration of contact elements, lacking the ability to easily adapt to different applications or combine with modular inserts.
Innovation Solution
A fixed-pole contact insert design that allows integration of modular contact inserts, featuring a holding frame or integral retaining frame for secure accommodation, and spring elements for easy insertion and locking, enabling flexible configuration and expansion with additional contact elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If contact elements are firmly integrated into the contact insert body, then structural stability is improved, but adaptability deteriorates
Solution Approach 1:
The contact insert is divided into a fixed-pole contact insert with firmly integrated contact elements and a separate modular contact insert that can be attached later. This segmentation allows the fixed part to maintain structural stability while the modular part provides adaptability for different applications.
Solution Approach 2:
The contact insert transitions from a completely fixed structure to a dynamic configuration where modular contact inserts can be added or removed. The receiving location and holding frame enable this dynamic adaptation while maintaining structural integrity through secure attachment mechanisms.
2Adaptability or versatility
If modular contact inserts are added to fixed-pole contact insert, then adaptability is improved, but device complexity is worsened
Solution Approach 1:
The fixed-pole contact insert with receiving location and holding frame serves multiple functions: it provides structural support, enables modular expansion, and ensures secure attachment. This multi-functionality reduces the need for separate components and simplifies the overall system despite increased adaptability.
Solution Approach 2:
The modular contact insert is designed to be inserted into and nested within the fixed-pole contact insert's holding frame. This nesting approach allows compact integration of multiple contact elements without significantly increasing the overall device footprint or complexity.
3Ease of operation
If spring elements are used for securing modular contact insert, then ease of operation is improved, but manufacturing precision is worsened
Solution Approach 1:
The spring element provides self-adjusting locking force that automatically adapts to variations in manufacturing tolerances. When the modular contact insert is inserted, the spring element compresses and secures it in place without requiring precise pre-setting of the spring force, making the system tolerant to manufacturing variations while maintaining ease of operation.
