Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If evaporator is used for heating and moisture absorption in existing washer-dryer machines, then high-temperature air is obtained to evaporate moisture in laundry, but the overall temperature of the evaporator is consistent causing moisture absorption capability to decrease, resulting in low moisture absorption efficiency, long drying time, and high power consumption
Solution Approach 1:
The evaporator is divided into multiple independent heating zones (first heating zone, second heating zone, third heating zone) with different temperature ranges. Each zone has its own heating assembly and can operate independently, allowing simultaneous moisture absorption at different temperature levels to improve overall drying efficiency while managing energy consumption through zoned control
Solution Approach 2:
Different regions of the evaporator are assigned different thermal properties - the first heating zone operates at higher temperature for initial moisture removal, while subsequent zones operate at progressively lower temperatures. This local differentiation of thermal characteristics allows the system to maintain high moisture absorption capability throughout the air circulation cycle
2Productivity
If condensed water spraying or condenser is used for direct dehumidification of wet air flow, then moisture is removed from air flow, but the air flow still contains high proportion of moisture requiring repeated heating-cooling and dehumidification-reheating cycles, resulting in low dehumidification efficiency and high power consumption
Solution Approach 1:
The system establishes a continuous dehumidification process where the evaporator continuously absorbs moisture from the air flow passing through its multiple heating zones. The regenerated dehumidified air is then directly used for drying without requiring cooling and reheating cycles, maintaining continuous useful action in moisture removal and eliminating energy-wasting temperature cycling
Solution Approach 2:
The system recovers the dehumidified air after moisture removal and reuses it directly in the drying process. Instead of discarding the air after condensation or cooling, the system maintains it in a suitable state for immediate reuse, eliminating the need for repeated heating and cooling cycles and significantly reducing energy consumption

AI summary
A drying module and a washing and drying integrated machine. A wet circulating air flow from a drum is conveyed by means of a circulation module to a dehumidification module for drying, and the dehumidification module adsorbs moisture from the wet circulating air flow from the drum, such that a dry circulating air flow is outputted to the drum. A regeneration module enables a dry regenerated air flow to be outputted to the dehumidification module so that at least a part of the dehumidification module desorbs moisture and regains a moisture adsorption capacity. A condensation module is used for condensing the regenerated air flow, which is outputted by the regeneration module, so as to form a low-temperature dry regenerated air flow. Condensate water formed during condensation is discharged. The dehumidification module, the circulation module and the condensation module are modules independent of each other.
