Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate temperature sensor and voltage sensor are provided with separate connections to the busbar, then temperature and voltage can be measured, but the connection structure becomes complex and the risk of connection failure increases
Solution Approach 1:
The patent combines the temperature sensor and voltage sensor into a single integrated measuring assembly that connects to the busbar through one unified connection structure. The contact element serves dual purposes: it provides electrical contact for voltage measurement and thermal contact for temperature measurement, eliminating the need for separate connections and reducing overall system complexity.
Solution Approach 2:
The contact element is designed as a multi-functional component that simultaneously performs electrical conduction for voltage sensing and thermal conduction for temperature sensing. This universal component replaces what would traditionally require two separate sensors and two separate connection paths, thereby simplifying the connection structure while maintaining measurement capabilities.
2Reliability
If separate sensors with separate connections are used, then temperature and voltage measurement is possible, but manufacturing cost increases
Solution Approach 1:
By merging the temperature sensing function and voltage sensing function into a single measuring assembly, the patent reduces the total number of components that need to be manufactured, procured, and assembled. This consolidation lowers manufacturing costs while maintaining the accuracy of both measurements through the integrated design.
3Reliability
If separate fixation methods are used for each sensor, then secure attachment is achieved, but the number of fixation points increases leading to higher failure risk
Solution Approach 1:
The patent uses a single fixation clip to secure the entire measuring assembly (containing both temperature and voltage sensors) to the busbar. This unified fixation approach reduces the number of fixation points from multiple separate attachments to just one, thereby reducing the potential failure points while maintaining secure attachment of both sensing functions.
4Measurement precision
If separate connections are provided for temperature and voltage sensing, then both measurements can be taken, but heat transfer for temperature sensing is insufficient
Solution Approach 1:
The integrated contact element provides both electrical contact and thermal contact through the same physical interface with the busbar. This merging of functions ensures optimal thermal coupling for accurate temperature measurement while simultaneously providing the electrical connection needed for voltage measurement, eliminating the heat transfer insufficiency that would result from separate, potentially less optimal connection paths.
