Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connecting elements for conductive surfaces in electronic devices face challenges in forming reliable and efficient galvanic contacts, particularly in terms of contact quality and reliability, due to variations in design and structure.
Innovation Solution
A connecting element comprising a body plate and a spring tab with upper and lower contact sections, where the spring tab is flexible and can transition from a rest position to a compressed position, allowing for secure galvanic contact between conductive surfaces without direct contact between the body plate and the surfaces, using a spring-like mechanism to ensure reliable connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a rigid connecting element is used to ensure stable positioning, then positioning accuracy is improved, but contact reliability deteriorates due to inability to accommodate surface variations
Solution Approach 1:
The spring tab is designed to be flexible and capable of bending, transforming the rigid structure into a dynamic one that can adapt to surface variations while maintaining contact pressure, thus resolving the contradiction between stable positioning and contact reliability
Solution Approach 2:
The spring tab's flexibility parameter is specifically optimized to allow controlled bending within a defined range, enabling the connecting element to maintain both positioning accuracy and contact reliability by adjusting its deformation state based on assembly conditions
2Reliability
If a flexible spring tab is used to improve contact reliability, then contact quality is improved, but positioning accuracy deteriorates due to potential deformation
Solution Approach 1:
The spring tab's controlled flexibility allows it to deform only within a specific range that does not compromise positioning accuracy, while still providing sufficient compliance to ensure reliable contact, thus resolving the contradiction between contact quality and positioning accuracy
Solution Approach 2:
The spring tab is designed with specific geometric features that concentrate flexibility in certain areas while maintaining rigidity in others, allowing localized deformation for contact reliability without affecting overall positioning accuracy
3Reliability
If the spring tab extends below the bottom level to ensure contact, then contact reliability is improved, but device complexity increases
Solution Approach 1:
The connecting element is segmented into distinct functional zones: the body plate provides structural support and positioning, while the spring tab provides compliant contact, allowing each part to be optimized independently for its specific function, thus resolving the contradiction between contact reliability and structural simplicity

Function Achieved in This Case
The solution enables accurate positioning and secure galvanic connections between conductive surfaces, improving the reliability and quality of electrical contacts, while allowing for the use of non-conductive adhesives and reducing mechanical wear on the surfaces.
Implementation Method 1
a spring tab extending from the body plate and having a spring tab upper surface comprising an upper contact section above the body plate top level... The spring tab may have a rest position or rest state in which, with no external force applied onto the upper contact section, the lower contact section of the spring tab lower surface lies above the connecting element bottom level, to a compressed position or compressed state in which the lower contact section lies in or below the connecting element bottom level
