Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If batteries are placed in a cabinet for protection, then battery safety is improved, but temperature and humidity control becomes difficult leading to battery corrosion and reduced lifespan
Solution Approach 1:
The cabinet is divided into multiple functional zones: a first cabinet body for battery placement, a second cabinet body for equipment housing, and a third cabinet body forming a heat exchange chamber. This segmentation allows independent control of temperature and humidity in different regions, solving the problem of maintaining battery safety while enabling effective environmental control.
Solution Approach 2:
A heat exchange medium (refrigerant) is introduced as an intermediary substance to transfer heat between the battery cabinet and the external environment. The medium circulates through heat exchange plates and pipes, enabling temperature regulation without direct contact between cooling components and batteries, thus maintaining both safety and thermal control.
2Loss of energy
If heat exchange plate is in direct thermal contact with battery, then heat dissipation efficiency is improved, but deployment flexibility is reduced
Solution Approach 1:
The heat exchange system is segmented into removable heat exchange plates that can be independently installed or removed. Each plate can be selectively placed based on battery configuration requirements, maintaining efficient thermal contact where needed while allowing flexible deployment in different installation scenarios.
Solution Approach 2:
The heat exchange plates are designed with dynamic positioning capabilities, allowing them to be adjusted to different positions and orientations within the cabinet. This enables the system to adapt to various battery layouts and installation environments while maintaining optimal thermal contact for efficient heat dissipation.
3Object-affected harmful factors
If dehumidification component is added to control humidity, then battery corrosion is prevented, but device complexity increases
Solution Approach 1:
The dehumidification function is merged with the existing heat exchange system. The heat exchange medium serves dual purposes: cooling the batteries and condensing moisture from the air. By combining these functions into a single integrated system, the patent prevents battery corrosion without significantly increasing device complexity.
Solution Approach 2:
The heat exchange medium and associated components perform multiple functions simultaneously: thermal regulation, humidity control, and heat dissipation. This multi-functionality eliminates the need for separate dedicated dehumidification equipment, maintaining system simplicity while achieving comprehensive environmental protection for the batteries.
