Conductive Elastic Piece Assembly for Stable Sliding Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elastic piece assemblies in electronic devices face challenges in controlling deformation, leading to unstable electrical contacts when the elastic force is low and increased friction when it is high, affecting relative sliding between components.
Innovation Solution
The elastic piece assembly is designed with both ends connected to a support, featuring a fixed end for reliable connection, a connecting end that moves relative to the support to limit protrusion height, and accommodating grooves to prevent reverse installation, along with inclined parts for buffering, ensuring stable electrical contact and smooth sliding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the elastic force of the elastic pieces is increased to ensure stable electrical contact, then the contact stability is improved, but the friction between components increases, affecting relative sliding
Solution Approach 1:
The elastic piece is divided into multiple independent elastic units (first elastic piece, second elastic piece, etc.), each providing localized elastic contact. This segmentation allows the system to achieve stable electrical contact through multiple small contact points rather than one large contact force, reducing overall friction while maintaining contact stability.
Solution Approach 2:
Different portions of the elastic piece have different functional properties: the bending portion provides elastic contact force for electrical connection, while the connecting portions are designed to minimize friction during sliding. This local differentiation optimizes both contact stability and sliding performance.
2Ease of operation
If the elastic force of the elastic pieces is decreased to reduce friction, then the sliding performance is improved, but the contact stability becomes unstable
Solution Approach 1:
Multiple elastic pieces work in parallel, where each piece provides a portion of the total contact force. This allows the system to use lower individual elastic forces (reducing friction) while maintaining overall contact stability through the cumulative effect of multiple contact points.
Solution Approach 2:
Multiple elastic pieces are combined to work together as a unified electrical connection system. The cumulative effect of multiple low-force elastic contacts achieves the same stability as a single high-force contact, while significantly reducing friction and improving sliding performance.
3Reliability
If the conductive elastic piece is made more rigid to maintain stable contact, then the contact reliability is improved, but the ability to accommodate relative movement is reduced
Solution Approach 1:
The elastic piece is designed with specific bending portions that can dynamically deform during relative movement between components. These bending portions flex to accommodate sliding motion while maintaining continuous electrical contact, providing both reliability and adaptability to movement.
Solution Approach 2:
The elastic piece uses flexible conducting material with controlled thickness and geometry to create regions that can bend and deform. This flexibility allows the piece to adapt to relative movements while maintaining stable electrical connection through elastic contact.

AI summary
Embodiments of this application provide an elastic piece assembly and an electronic device with an elastic piece assembly. The elastic piece assembly includes a support, an electrical contact assembly, and at least two conductive elastic pieces, where two end portions of each of the conductive elastic pieces are connected to the support, the conductive elastic piece is provided with an electrical contact section bent toward the electrical contact assembly, and the electrical contact section is located between two ends of the conductive elastic piece. The conductive elastic pieces are sequentially arranged in a first direction, and when the first component and the second component slide relatively, the electrical contact assembly abuts against the electrical contact sections of different conductive elastic pieces to connect the electrical contact assembly to the conductive elastic pieces. In the elastic piece assembly, the two ends of each of the conductive elastic pieces are connected to the support, so that deformation of the conductive elastic piece is controlled to ensure that the electrical contact section of the conductive elastic piece has enough elasticity to be in contact with the electrical contact assembly, and the conductive elastic piece is prevented from affecting relative sliding between the first component and the second component.
