Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery connection methods, particularly for high-voltage connectors, suffer from size compatibility issues leading to connection failures, noise, and increased manufacturing costs due to brittle materials, which affect reliability and customer satisfaction.
Innovation Solution
Employing a flexible cable tie with dual snapping portions and locking teeth for adjustable and secure connections, allowing for size adaptation and improved stability, while ensuring electrical isolation and protection against accidental loosening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional rigid connecting elements are used for battery connections, then manufacturing precision can be maintained, but adaptability to different component sizes deteriorates
Solution Approach 1:
The cable tie body is designed to be flexible and deformable, transitioning from an unfolded state to a wrapping state around connecting elements. This dynamic adaptation allows the same cable tie to accommodate different component sizes while maintaining secure connections through the snapping portions that lock at optimal positions.
Solution Approach 2:
The cable tie's physical state changes from straight (unfolded) to curved (wrapped), and the snapping portions engage at variable positions along the cable tie body. This parameter change enables the connection structure to adapt to different component dimensions while maintaining precise and reliable connections.
2Reliability
If brittle materials are used for connecting elements, then manufacturing costs can be reduced, but reliability of connections deteriorates
Solution Approach 1:
The cable tie body is made from flexible material that can be continuously formed and shaped, replacing traditional brittle rigid connectors. This flexible construction maintains connection reliability through elastic deformation and secure locking mechanisms while enabling more cost-effective manufacturing processes.
Solution Approach 2:
The dual snapping portions automatically lock the cable tie body to the connecting elements without requiring additional fastening operations. The cable tie self-adjusts and self-secures during installation, improving reliability while simplifying the manufacturing and assembly process.
3Stability of the object's composition
If single snapping portion cable ties are used, then device complexity is reduced, but stability of connections deteriorates
Solution Approach 1:
The cable tie incorporates two distinct snapping portions (first and second snapping portions) spaced apart along the cable tie body. This segmentation provides dual locking points that independently secure the connection, significantly enhancing stability while keeping each individual snapping mechanism relatively simple.
Solution Approach 2:
The first and second snapping portions are integrated into a single continuous cable tie body, combining multiple securing functions into one component. This merging approach improves connection stability through dual locking while avoiding the complexity of separate fastening devices.
4Object-affected harmful factors
If cable ties without isolation features are used, then device complexity is reduced, but harmful factors increase due to lack of electrical isolation
Solution Approach 1:
The cable tie body serves multiple functions simultaneously: it provides mechanical securing through the snapping portions, electrical isolation between connecting elements, and physical protection. This multi-functionality addresses harmful factors like electrical contact while avoiding the need for separate isolation components.
Solution Approach 2:
The cable tie body acts as an intermediary barrier between connecting elements, providing electrical isolation while maintaining mechanical connection. This mediator function prevents harmful electrical contact between components while the overall structure remains relatively simple.

AI summary
Embodiments of the present application provide a flexible tie, an electrical connection structure, and a battery. The flexible tie comprises a tie body, a first fastening part, and a second fastening part; the first fastening part and the second fastening part are provided at a first end of the tie body; a preset distance is formed between the first fastening part and the second fastening part; the tie body has an unfolded state and a wrapping state; in the unfolded state, the first fastening part and the second fastening part are provided on the same side of the tie body; and in the wrapping state; a second end of the tie body is connected to the first fastening part and the second fastening part. The flexible tie of the present application comprises two fastening parts which can implement dual fixing for the second end of the tie body, thereby effectively improving the reliability of connection; and since a preset distance is formed between the two fastening parts, parts wrapped by the flexible tie can be placed on the two sides of the second fastening part respectively, thereby meeting an isolation requirement of the parts wrapped by the flexible tie.
