Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an electrochemical sensor switch with product identifying compound is used to verify authenticity, then the reliability of product verification is improved, but the device complexity increases
Solution Approach 1:
The patent uses electrochemical sensor switches that change conductivity parameters when exposed to specific product identifying compounds. This allows the system to verify product authenticity by detecting changes in electrical conductivity, enabling reliable verification through measurable parameter changes rather than complex mechanical or optical systems
Solution Approach 2:
The patent replaces potential mechanical verification systems with an electrochemical sensing system. The electrochemical sensor switch uses chemical reactions between the product identifying compound and sensor materials to produce electrical signals, substituting mechanical complexity with electrochemical detection that is both reliable and more compact
2Manufacturing precision
If the system is configured to prevent refilling by limiting use to a single cycle, then the manufacturing precision of quality control is improved, but the loss of time for product replacement increases
Solution Approach 1:
The system performs preliminary verification of product authenticity before allowing use. The electrochemical sensor switch detects the product identifying compound in advance, confirming authenticity and enabling the system to control subsequent usage cycles. This preliminary check ensures quality control before the product is activated, preventing counterfeit or refilled products from being used
Solution Approach 2:
The system uses feedback from the electrochemical sensor switch to control product usage. When the sensor detects the product identifying compound, it triggers a state change that allows the device to operate for a controlled number of cycles. After the predetermined number of cycles, the system provides feedback to prevent further use, ensuring quality control while managing product lifecycle
