Spring Member Segmentation for Stable Electrical Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electrical connection structures for connecting a power supply part on a glass plate to a connection terminal using a spring member are unstable due to varying contact areas, leading to fluctuations in electrical current flow.
Innovation Solution
An electrical connection structure featuring a spring member with a fixing part, a curved part, and contact parts, where the curved part is branched by a slit and contacts the power supply part and base part independently, and an adhesive member is used to secure the base part to the glass plate, preventing excessive deformation and stabilizing the connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spring member is used to electrically connect the power supply part to the connection terminal, then electrical connection is achieved, but the contact area varies causing unstable connection
Solution Approach 1:
The spring member is divided into multiple independent contact parts (first contact part and second contact part) separated by a slit. This segmentation allows each contact part to independently contact the base part, ensuring stable electrical connection even when the overall contact area varies due to manufacturing tolerances or assembly variations.
Solution Approach 2:
Different parts of the spring member have different functional qualities: the curved part provides elastic deformation capability for electrical connection, while the contact parts provide stable contact with the base part. The slit creates local independence in the contact regions, allowing each contact part to adapt locally to ensure consistent contact.
2Reliability
If the curved part protrudes toward the glass plate to contact the power supply part, then electrical connection is enabled, but excessive deformation may occur
Solution Approach 1:
The slit divides the curved part into first and second branch parts, which can deform independently. This segmentation distributes the deformation stress and prevents excessive deformation at any single point while maintaining the electrical connection function.
Solution Approach 2:
The spring member is designed to be dynamically deformable within safe limits. The curved geometry and slit configuration allow controlled elastic deformation to accommodate assembly variations and thermal expansion, while the material and geometric design prevent deformation beyond safe thresholds that would compromise structural integrity.
