Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional heating structures are used in laundry machines, then the structure is simple, but heat transmission occurs in unwanted directions reducing efficiency
Solution Approach 1:
The heating structure is segmented into multiple independent heating parts (first heating part, second heating part, third heating part) with distinct functions. Each heating part is positioned to control heat transmission in specific directions, preventing unwanted heat loss while maintaining overall system efficiency without excessive complexity.
Solution Approach 2:
Different regions of the heating structure are assigned different thermal properties. The first heating part uses a first heat transmission direction, the second heating part uses a second heat transmission direction, and the third heating part is positioned to prevent heat transmission in specific directions. This local differentiation optimizes heat distribution efficiency.
2Volume of moving object
If heating parts are positioned close to each other to save space, then the device is compact, but overheating risks increase
Solution Approach 1:
Each heating part is assigned a specific spatial orientation and heat transmission direction. The first heating part transmits heat in a first direction, the second heating part in a second direction, and the third heating part prevents heat transmission in certain directions. This localized control allows compact arrangement while preventing heat accumulation and overheating through directional heat management.
3Loss of energy
If heat-insulating materials are used to prevent heat loss, then energy efficiency improves, but the exterior appearance may be compromised
Solution Approach 1:
Heat-insulating materials are applied selectively in specific regions where heat loss occurs, rather than uniformly across the entire exterior. The third heating part is specifically positioned to prevent heat transmission in directions that would cause energy loss while maintaining aesthetic appearance. This localized insulation approach balances energy efficiency with exterior appearance.
