Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional washing and drying machines with heat pump mechanisms face challenges in achieving faster air circulation and larger air volume due to longer circulatory ventilation flues, leading to longer drying times and higher power consumption.
Innovation Solution
The design positions the heat pump device and filter in the upper space of the housing, creating a shorter circulatory ventilation flue and optimizing the flow path to reduce pressure loss, enhance heat exchange efficiency, and improve air circulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the heat pump mechanism is disposed in the lower space of the housing, then the structure is stable and components are easily accessible, but the circulatory ventilation flue becomes longer which increases pressure loss and reduces air circulation efficiency
Solution Approach 1:
The patent repositions the heat pump mechanism from the lower space to the upper space of the housing, changing the spatial dimension of component arrangement. This dimensional change shortens the circulatory ventilation flue path, reducing pressure loss and improving air circulation efficiency while maintaining service accessibility through the front-opening design.
2Stability of the object's composition
If the circulatory ventilation flue is made longer to accommodate heat pump in lower space, then structural stability is improved, but pressure loss increases and drying time extends
Solution Approach 1:
By moving the heat pump mechanism to the upper space and reconfiguring the ventilation flue path, the patent reduces the flue length and optimizes the air circulation route. This dimensional rearrangement decreases pressure loss and shortens drying time while maintaining structural integrity through optimized support arrangements.
3Productivity
If the heat pump mechanism is placed in the upper space, then the circulatory ventilation flue is shortened and air circulation is improved, but the weight distribution and structural stability may be affected
Solution Approach 1:
The patent implements upper space positioning of the heat pump mechanism with optimized support structures that distribute weight effectively. This dimensional change improves air circulation efficiency by shortening the ventilation flue while maintaining structural stability through engineered support arrangements.
4Use of energy by stationary object
If the circulatory ventilation flue is shortened, then pressure loss is reduced and power consumption decreases, but the arrangement of components becomes more constrained
Solution Approach 1:
The patent merges the heat pump mechanism and circulation pump into a integrated assembly positioned in the upper space, and combines the ventilation flue with the housing structure. This merging reduces component arrangement complexity while achieving shorter flue length, reduced pressure loss, and lower power consumption.
