Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If visual inspection by operators is used to assess water turbidity, then the inspection method is easy to perform, but the results are highly subjective and lack consistency
Solution Approach 1:
The patent replaces the mechanical/visual inspection system with an optical sensing system. A laser sensing device emits laser light through the water sample, and a photodetector measures the light transmission. This substitution eliminates human subjectivity while maintaining ease of operation, as the automated optical system requires minimal manual intervention and provides consistent, objective measurements of water turbidity.
Solution Approach 2:
The patent introduces an optical intermediary (laser light) to mediate between the water sample and the measurement system. The laser light passes through the water sample, and its attenuation is measured by the photodetector. This intermediary enables precise, consistent measurement of water turbidity without requiring direct visual inspection by operators.
2Measurement precision
If automated laser sensing is used to determine washing quality, then consistent and objective results are achieved, but the device complexity increases
Solution Approach 1:
The patent segments the inspection system into distinct functional modules: a sampling unit for collecting water samples, an impurity removing module for filtering debris, a water sample inspection area for holding the sample, and a laser sensing device for measurement. This segmentation allows each component to be optimized independently and simplifies maintenance while achieving consistent, objective washing quality determination.
Solution Approach 2:
The patent performs preliminary actions by automatically sampling water from the washing machine and filtering out large impurities before the laser sensing measurement. The sampling unit collects water samples automatically, and the impurity removing module pre-filters the sample to remove debris that could interfere with the optical measurement. This preliminary preparation ensures accurate measurements without requiring complex post-processing.
3Reliability
If multiple washing cycles are performed to ensure quality, then washing quality is improved, but water and energy consumption increase
Solution Approach 1:
The patent implements a feedback mechanism where the laser sensing device continuously monitors water turbidity during and after washing cycles. The main control unit receives the transparency values and compares them against predetermined thresholds. When the washing quality meets the required standards, the system automatically terminates the washing process. This feedback control ensures reliable washing quality while minimizing water and energy consumption by avoiding unnecessary extended washing cycles.
Solution Approach 2:
The system performs self-service by automatically determining washing quality through the laser sensing device and autonomously deciding when to terminate the washing process. The main control unit uses the transparency values to make real-time decisions about washing duration, eliminating the need for manual intervention and preventing excessive washing that would waste water and energy while ensuring consistent quality.

AI summary
A method and device for identifying the washing quality of a feather material are applied to a feather material washing apparatus and essentially entail: a sampling unit that takes an appropriate amount of the water discharged from the feather material washing apparatus as a water sample, an impurity removing module that removes feather fiber and impurities that may compromise inspection accuracy, and a laser sensing device that senses, while the water sample is static, a transparency value of a portion of the water sample that extends across a predetermined distance, in order to identify the washing quality of a washed feather material. The method and device for identifying the washing quality of a feather material exercise intelligent judgment to enable a consistent standard, to ensure the efficiency and quality of a feather material washing procedure, and to reduce the associated costs.
