Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If a blanket covers the battery to capture CO2 from ambient air, then CO2 capture capability is improved, but device complexity increases
Solution Approach 1:
The blanket is designed to perform multiple functions simultaneously: CO2 capture through chemical absorption materials, thermal insulation to maintain battery temperature, and fire suppression through fire-retardant properties. This multi-functionality resolves the technical contradiction by integrating CO2 capture with existing battery protection requirements, avoiding the need for separate systems and thereby limiting the increase in device complexity.
Solution Approach 2:
The invention uses a flexible blanket structure rather than rigid enclosures to cover the battery. This thin film approach enables CO2 capture functionality to be added without significant structural complexity, as the blanket can be draped over existing battery configurations and integrated into the vehicle's existing battery compartment space.
2Object-generated harmful factors
If a blanket covers the battery for CO2 capture, then CO2 capture capability is improved, but manufacturing complexity increases
Solution Approach 1:
The blanket incorporates porous materials containing CO2-absorbing chemicals such as lithium hydroxide, sodium hydroxide, or soda lime. These porous structures provide high surface area for CO2 absorption while maintaining a simple blanket form factor. The porous material can be integrated into the blanket during manufacturing through impregnation or coating processes, avoiding complex assembly steps and limiting manufacturing complexity.
3Adaptability or versatility
If the blanket is made flexible to cover battery contours, then adaptability is improved, but structural strength decreases
Solution Approach 1:
The blanket is constructed as a composite material system combining a flexible fabric substrate with fire-retardant and CO2-absorbing material layers. The fabric base provides flexibility and mechanical strength, while the integrated functional layers provide chemical absorption and fire suppression. This composite structure resolves the contradiction by distributing structural requirements across multiple material layers, each optimized for its specific function while working together to provide both flexibility and strength.
