Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a case is used to house the control circuit, then the control circuit is protected and securely mounted, but manufacturing costs increase and heat dissipation efficiency decreases
Solution Approach 1:
The patent divides the housing structure into separate functional components: cell holders for mounting electrochemical cells and a control circuit holder for mounting the control circuit. This segmentation eliminates the need for a single enclosing case while providing dedicated mounting structures for each component, reducing manufacturing cost while maintaining protection and security of the control circuit.
Solution Approach 2:
The control circuit is extracted from the traditional enclosed case structure and mounted separately on a dedicated control circuit holder that is attached to the cell holder assembly. This extraction allows the control circuit to be securely mounted without requiring a full enclosing case, thereby reducing manufacturing cost while maintaining reliability through dedicated mounting and protection.
2Reliability
If a case is used to house the control circuit, then the control circuit is protected and securely mounted, but heat dissipation efficiency decreases
Solution Approach 1:
By segmenting the housing into separate cell holders and control circuit holder, the patent creates open structures that do not enclose the electrochemical cells. This allows heat generated by the cells to dissipate freely into the surrounding environment rather than being confined within a closed case, thereby improving heat dissipation efficiency while maintaining control circuit protection through its dedicated holder.
Solution Approach 2:
The control circuit is taken out from a traditional enclosing case and mounted on a separate holder attached to the cell holder. This extraction eliminates the enclosing case that would trap heat, allowing the electrochemical cells to dissipate heat efficiently while the control circuit remains protected and securely mounted on its dedicated holder.
3Reliability
If a case is used to house the control circuit, then the control circuit is protected, but control malfunction due to noise is more likely to occur
Solution Approach 1:
The control circuit is extracted from proximity to the electrochemical cells by mounting it on a separate control circuit holder attached to the cell holder assembly. This spatial separation reduces exposure to electromagnetic noise and other harmful factors generated by the cells, thereby reducing the likelihood of control malfunction while maintaining protection through the dedicated holder structure.
