Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple temperature sensors are placed at different locations in the battery module to obtain comprehensive temperature information, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines multiple temperature sensing functions into a single thermal management film that can be applied to the battery module surface. The film integrates multiple sensing elements and regulatory components that work together to provide comprehensive temperature monitoring across multiple locations simultaneously, eliminating the need for separate discrete sensors at each position.
Solution Approach 2:
The thermal management film serves multiple functions: it acts as both the temperature sensing arrangement and the temperature regulating arrangement. The film can detect temperature at multiple locations and simultaneously provide thermal regulation, making a single component perform what previously required multiple separate systems.
2Reliability
If separate thermal management components are installed to regulate temperature based on sensor detection, then temperature regulation effectiveness is improved, but device complexity and space consumption increase
Solution Approach 1:
The patent merges the temperature sensing arrangement and temperature regulating arrangement into a single integrated thermal management film. The sensing elements and regulatory elements (such as phase change materials or thermally conductive components) are combined in one film structure, eliminating the need for separate sensors and separate thermal management devices.
Solution Approach 2:
The thermal management film contains nested functional layers where sensing elements are embedded within or alongside the regulatory materials. The film structure itself is applied to the battery module surface, with regulatory elements positioned to directly respond to temperature variations detected by the integrated sensing elements.
3Area of stationary object
If multiple temperature sensors and thermal management components are deployed, then temperature monitoring and regulation coverage is improved, but space consumption increases
Solution Approach 1:
The patent extracts the thermal management functionality from bulky discrete components and consolidates it into a thin film structure. The thermal management film can be applied directly to the battery module surface, providing comprehensive temperature monitoring and regulation coverage without occupying additional internal space within the battery module.
