Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a detergent mixing system is implemented, then detergent and water can be mixed, but the system becomes complex and cumbersome
Solution Approach 1:
The dispenser and mixing chamber are merged into a single integrated module that is connectable to the washing machine casing. This combination eliminates the need for separate detergent storage and mixing components, thereby reducing constructional complexity while maintaining the functionality of detergent preparation.
Solution Approach 2:
The mixing chamber serves multiple functions: it stores detergent, mixes detergent with water, and delivers the solution to the washing machine. This multi-functionality reduces the need for separate components, simplifying the overall system construction while ensuring efficient detergent preparation.
2Manufacturing precision
If detergent is mixed with water in a separate mixing chamber, then uniform detergent solution is achieved, but the system becomes cumbersome
Solution Approach 1:
The mixing chamber is integrated with the dispenser to form a single module, combining storage and mixing functions in one component. This integration maintains uniform mixing capability while reducing the number of separate parts, thereby decreasing system complexity.
Solution Approach 2:
Detergent is pre-loaded into the mixing chamber module before use. The module is then connected to the washing machine, and water is added to create the detergent solution. This preliminary preparation simplifies the overall system by eliminating the need for complex real-time detergent dispensing mechanisms during the washing cycle.
