Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If near field frequency response key devices are used for dispensing control, then compatibility verification is achieved, but device complexity increases and manufacturing becomes difficult due to requirement of metal coils
Solution Approach 1:
The patent replaces the electromagnetic coil-based near field frequency response system with an optical waveguide system. The waveguide carries electromagnetic radiation from a transmitter through a frangible member to a receiver, providing compatibility verification without requiring metal coils or complex electromagnetic components. This substitution simplifies the device structure while maintaining reliability.
Solution Approach 2:
The patent extracts the essential function of compatibility verification from the complex coil-based system and implements it through a simplified optical path. By removing the metal coil requirement and using only plastic components with integrated waveguides, the system achieves the same verification purpose with reduced complexity.
2Reliability
If metal coils are used in key devices for dispensing control, then compatibility verification is achieved, but ease of manufacture deteriorates and recycling becomes difficult
Solution Approach 1:
The patent substitutes metal coil-based electromagnetic systems with optical waveguide technology that can be fully manufactured from plastic materials. The waveguide is integrated into the removable component housing, allowing the entire assembly to be molded as a single piece or easily assembled from plastic parts, significantly improving ease of manufacture and enabling recycling.
Solution Approach 2:
The patent uses plastic materials with specific optical properties to create the waveguide structure. The frangible member is also made from plastic or other easily manufacturable materials, allowing the entire key device to be produced through injection molding or similar processes, greatly simplifying manufacturing compared to metal coil assemblies.
3Ease of operation
If frangible waveguide members are used in removable components, then secure coupling and uncoupling control is achieved, but manufacturing precision requirements increase
Solution Approach 1:
The patent divides the waveguide structure into two segments: a permanent waveguide integrated into the housing and a frangible member that couples the removable component to the housing. The frangible member is designed with a specific break point that separates the coupling function from the permanent structure, allowing controlled failure mode upon removal attempts.
Solution Approach 2:
The frangible member is pre-designed with a predetermined break point and structural weakness that ensures it will fail in a controlled manner upon excessive force or removal attempts. This preliminary design of the failure mode reduces the need for high manufacturing precision during assembly, as the frangible nature provides built-in control.
