Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the container is tilted to pour out contents, then the contents can be discharged, but the discharge amount cannot be accurately controlled and spills occur
Solution Approach 1:
The patent replaces the mechanical tilting method with an optical sensing system. Light emitting parts and light receiving parts detect the passage of contents through optical means rather than mechanical observation, enabling precise measurement of discharged content without physical tilting or pouring actions.
Solution Approach 2:
The patent implements a feedback mechanism where the sensing part continuously monitors the discharge process and provides information to a control part. This feedback loop allows the system to track and control the discharge amount in real-time, preventing over-discharge and spills while maintaining ease of operation.
2Quantity of substance
If a fixed amount discharging container is used, then the discharge amount is controlled, but the sensing of discharged content is inaccurate
Solution Approach 1:
The patent replaces conventional mechanical or simple optical sensors with a sophisticated optical sensing system using light emitting diodes and photodetectors. This substitution enables accurate detection of content characteristics such as size, shape, and passage timing, significantly improving measurement precision while maintaining fixed amount discharge control.
Solution Approach 2:
The patent utilizes changes in optical parameters (light intensity, transmission, reflection) as contents pass through the sensing zone. By detecting these parameter changes, the system can accurately sense and identify individual contents, their quantities, and their discharge status, thereby improving measurement precision without compromising the fixed amount discharge mechanism.
3Device complexity
If conventional sensing methods are used, then the device structure is simple, but the content discharge cannot be accurately sensed
Solution Approach 1:
The patent replaces simple mechanical sensors or visual inspection methods with an optical sensing system. Although this increases device complexity, it provides accurate real-time detection of content discharge, enabling precise measurement and control that conventional methods cannot achieve.
Solution Approach 2:
The patent designs the sensing part to perform multiple functions: detecting content passage, identifying content characteristics, measuring discharge quantity, and providing feedback for control. This multi-functionality justifies the increased device complexity by delivering comprehensive and accurate discharge sensing capabilities in a single integrated system.
