Solution Overview
Problem
Existing equipotential connections between two electric conductors are prone to poor contact, leading to equipotential failure due to loose bolts or inadequate contact between the equipotential metal sheet and the conductors.
Innovation Solution
An equipotential structure utilizing an electrically-conductive member partially arranged on an elastic support, which applies an elastic support force to squeeze the conductive member tightly onto both electric conductors, ensuring a stable equipotential connection through the use of connectors passing through strategically placed holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bolts are used to fix the equipotential metal sheet to electric conductors, then the connection is mechanically secure, but poor contact and equipotential failure easily occur due to loose bolts or inadequate contact
Solution Approach 1:
The patent changes the physical state of the support from rigid to elastic, allowing dynamic adaptation. The elastic support deforms under compression to ensure continuous contact between the conductive member and electric conductors, transforming the connection from a static bolted joint to a dynamic elastic constraint system that maintains optimal contact pressure
Solution Approach 2:
The patent introduces dynamic elements by replacing static bolted connections with elastic supports that can deform and recover. The elastic support dynamically adjusts to maintain contact pressure, and the conductive member can flex to conform to the surfaces of the electric conductors, creating a self-adjusting connection system
2Adaptability or versatility
If a rigid equipotential metal sheet is used, then the structure is simple and stable, but it cannot adapt to surface irregularities or thermal expansion, leading to poor contact
Solution Approach 1:
The patent applies flexible elements by using an elastic support instead of a rigid structure. The elastic support can deform to accommodate surface irregularities and dimensional changes in the electric conductors, ensuring continuous contact without requiring complex adjustment mechanisms or multiple components
Solution Approach 2:
The equipotential apparatus combines different material properties by integrating an elastic support with an electrically conductive member. This composite structure merges the mechanical compliance of elastic materials with the electrical conductivity of conductive materials, achieving both adaptability and electrical function in a single integrated component system

AI summary
The present application provides an equipotential apparatus, an equipotential structure, a battery and an electric device, and belongs to the technical field of batteries. The equipotential apparatus includes an electrically-conductive member and an elastic support. The electrically-conductive member is at least partially arranged on a surface of the elastic support, and the elastic support is configured to provide an elastic support force for the electrically-conductive member so as to squeeze the electrically-conductive member to a first electric conductor and a second electric conductor to achieve an equipotential connection between the first electric conductor and the second electric conductor. The elastic support has the ability of performing an elastic deformation and recovering from the deformation. After being elastically deformed, the elastic support can provide an elastic support force for the electrically-conductive member. Under the effect of the elastic support force, the electrically-conductive member can be made to be squeezed to the first electric conductor and the second electric conductor, such that the electrically-conductive member is in close contact with the first electric conductor and the second electric conductor. Therefore, it is not easy to cause equipotential failure of the first electric conductor and the second electric conductor.
