Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a transfer mechanism is used to transfer the substrate, then the substrate can be moved during manufacturing, but the substrate may drop and break due to inability to detect bonding status
Solution Approach 1:
The patent implements a detection mechanism that provides real-time feedback on bonding status during substrate transfer. The detecting mechanism includes a sensing electrode that detects changes in capacitance or electric field when the spacer plate bonds to the substrate, allowing the system to receive feedback signals and adjust transfer operations accordingly, preventing substrate drops and breaks
Solution Approach 2:
The patent introduces a detecting mechanism as an intermediary between the transfer mechanism and the substrate. This intermediary device monitors the bonding process by detecting electrical parameters (capacitance changes) and communicates bonding status to the control system, enabling indirect observation and control of the bonding state without direct mechanical interference
2Measurement precision
If the detecting mechanism height is reduced to improve detection accuracy, then detection precision improves, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical detection structures with an electrical field-based detection system. The sensing electrode detects bonding through changes in capacitance or electric field characteristics, eliminating the need for complex mechanical measurement devices and reducing structural complexity while maintaining high detection precision
Solution Approach 2:
The patent changes the detection parameter from mechanical measurement to electrical parameter measurement (capacitance, electric field). By monitoring electrical parameter changes when the spacer plate bonds to the substrate, the system achieves precise detection without requiring complex mechanical structures, thus reducing device complexity while improving measurement precision
