Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each charging gun uses a separate heat dissipation module, then heat dissipation reliability is improved, but device complexity and cost increase
Solution Approach 1:
The patent merges multiple heat dissipation modules into a single shared heat dissipation module that serves multiple charging guns. The control unit coordinates heat dissipation resources among different charging guns, allowing them to share the same thermal management infrastructure while maintaining reliable heat dissipation performance through intelligent resource allocation.
Solution Approach 2:
The heat dissipation module is designed with universal applicability to serve multiple charging guns simultaneously. The control unit enables the single heat dissipation module to dynamically adapt and provide heat dissipation services to different charging guns based on their respective thermal needs, achieving multi-functionality from a single component.
2Productivity
If multiple charging guns charge simultaneously with separate heat dissipation modules, then charging output capacity is improved, but heat dissipation efficiency deteriorates due to low utilization
Solution Approach 1:
The control unit implements dynamic heat dissipation resource allocation that adjusts in real-time based on the charging status of different guns. When multiple charging guns operate simultaneously, the system dynamically coordinates their heat dissipation needs, ensuring the shared heat dissipation module operates at optimal utilization levels while supporting high charging output capacity.
Solution Approach 2:
The system changes operational parameters by allowing the heat dissipation module to serve multiple charging guns with varying power levels. The control unit monitors and adjusts heat dissipation parameters dynamically, enabling the single module to efficiently handle different thermal loads from multiple charging guns simultaneously, thereby improving both output capacity and heat dissipation efficiency.
3Device complexity
If a single heat dissipation module serves multiple charging guns, then device complexity is reduced, but heat dissipation reliability may deteriorate
Solution Approach 1:
The control unit implements a feedback mechanism that continuously monitors the thermal status of each charging gun and the operational state of the shared heat dissipation module. Based on this feedback, the control unit dynamically adjusts heat dissipation resource allocation to ensure that each charging gun receives adequate thermal management, thereby maintaining high reliability despite using a single shared module.
Solution Approach 2:
The control unit enables the heat dissipation system to self-regulate and self-optimize by automatically coordinating thermal management resources among different charging guns. The system autonomously adjusts heat dissipation allocation based on real-time conditions, ensuring reliable performance while simplifying the overall device architecture through the use of a single shared module.
