Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing accumulator packs for heating elements, typically housed in rigid cases, face challenges with mechanical stress and weather exposure, making battery replacement inconvenient and costly, and prone to damage.
Innovation Solution
A battery pack design featuring a housing shell with a removable cap that includes a control circuit and a flexible or rigid cover, providing protection against mechanical and weather influences, with resilient contact elements for maintaining power supply during impacts and a short-circuit protection circuit for safety, along with a non-volatile memory for maintaining operating state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid housing is used to protect the battery pack, then mechanical strength is improved, but ease of battery replacement deteriorates and cost increases
Solution Approach 1:
The housing is divided into a modular structure with a removable cap that can be easily detached to access and replace batteries. This segmentation allows the protective housing to maintain its structural integrity while enabling convenient battery replacement through the removable cap component.
2Strength
If a rigid housing is used to protect the battery pack, then protection against mechanical stress is improved, but susceptibility to damage from mechanical stress worsens
Solution Approach 1:
The patent employs a flexible sleeve made of elastomer material that covers and protects the battery pack. This flexible protective layer absorbs mechanical stresses and impacts, preventing damage to the internal components while maintaining the overall structural integrity of the housing.
3Reliability
If resilient contact elements are used to maintain power supply during impacts, then reliability of power supply is improved, but device complexity increases
Solution Approach 1:
The contact elements are designed with resilient properties that allow them to elastically deform and maintain electrical contact under varying mechanical conditions. This parameter change in the contact elements' physical state enables them to absorb impacts and ensure continuous power supply without requiring complex additional mechanisms.
