Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sensors (liquid level, turbidity, temperature) are independently installed in different positions, then each sensor can perform its sensing function, but the system wiring becomes complex and occupies large space
Solution Approach 1:
The patent combines multiple independent sensors (liquid level sensor, turbidity sensor, temperature sensor) into a single integrated sensor module. The housing encapsulates all sensing components, allowing them to be installed at the same position rather than in different positions, thereby simplifying wiring and reducing space occupation while maintaining all sensing functions
Solution Approach 2:
The integrated sensor module performs multiple sensing functions (liquid level detection, turbidity detection, temperature detection) within a single device. The housing and circuit board support all sensor types, enabling one component to serve multiple purposes that previously required separate independent sensors
2Reliability
If multiple sensors are independently installed in different positions, then each sensor can detect its parameter, but the structure occupies relatively large system space
Solution Approach 1:
The patent merges multiple sensors into a single compact housing structure. The liquid level sensor, turbidity sensor, and temperature sensor are all enclosed within the same housing, eliminating the need for separate installation positions and significantly reducing the space occupied in the washing machine system
3Measurement precision
If sensors are independently installed, then each sensor can be optimized for its specific function, but the integration of multiple sensors becomes complicated
Solution Approach 1:
The patent segments the sensor module into distinct functional components (liquid level sensing module, turbidity sensing module, temperature sensing module) that can be independently designed and optimized, while the housing and circuit board provide unified integration. This allows each sensor to maintain its optimization while simplifying overall manufacturing through modular assembly

AI summary
A sensor module comprises a housing and a liquid level sensing module. The housing includes a first passage adapted to permit liquid to flow into an interior of the housing. The first passage defines an air chamber and an air passage in communication with the air chamber. The liquid level sensing module is arranged in the interior of the housing, and includes at least a first part positioned within the air passage. The liquid level sensing module is adapted to sense a characteristic indicative of a liquid level when the liquid flows into the first passage and compresses air in the air passage.
