Battery Pack Cable Seating Structure for Housing Interference Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery packs face issues with cable interference and damage due to external impacts, leading to potential safety hazards such as short circuits, fires, or explosions.
Innovation Solution
A battery pack design that includes a seating part to fix the position of the cable part, preventing interference between the housing part and the cable part, and maintaining a stable electrical connection by using a connector frame and seating part to support the cable, which is spaced apart from the housing part.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the cable part is disposed inside the battery pack without support structure, then the device complexity is reduced, but the cable part interferes with the housing part and may be damaged due to external impacts
Solution Approach 1:
The patent introduces a seating part as an intermediary component between the cable part and the housing part. This seating part provides support and positioning for the cable, preventing direct contact and potential damage between the cable and housing, thereby resolving the contradiction between simple structure and reliable connection.
2Ease of manufacture
If the cable part is freely disposed inside the battery pack, then the ease of manufacture is improved, but the cable part moves and interferes with other parts during usage
Solution Approach 1:
The seating part is pre-installed in the housing part before cable assembly. This preliminary action creates a predetermined positioning structure that guides and stabilizes the cable during subsequent assembly, ensuring the cable maintains a stable position without complex assembly procedures.
3Reliability
If the cable part is spaced apart from the housing part using support structures, then the interference between cable and housing is prevented, but the device complexity increases
Solution Approach 1:
Instead of providing comprehensive support structures throughout the battery pack, the patent applies the seating part only at the specific location where the cable requires support and positioning. This localized approach provides necessary protection while minimizing the addition of structural complexity.

AI summary
Discussed is a battery pack and a battery device including the battery pack. The battery pack includes a cable part, a connector part having one end to which the cable part is connected, a housing part on which the connector part is mounted, and a seating part configured to fix a position of the cable part. The cable part extends between the connector part and an inner surface of the housing part, and the seating part is disposed inside the housing part and configured to support one side of the cable part that faces the inner surface of the housing part so as to prevent an interference between the inner surface of the housing part and the cable part.
