Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing technologies use optocoupler or communication-based chip for switch control, then the electrical device can be controlled remotely, but the circuit needs to process multiple types of signals which causes conversion errors and reduces reliability
Solution Approach 1:
The patent extracts and eliminates the complex signal conversion components (optocoupler, communication chip) from the circuit. By removing these intermediate conversion elements, the circuit directly processes only voltage signals, thereby eliminating conversion errors and improving reliability while maintaining remote control capability through the simplified voltage signal processing architecture.
Solution Approach 2:
The patent changes the signal processing parameter from multiple signal types (optical, electrical, communication) to a single voltage signal parameter. This parameter simplification ensures that the controller only handles voltage signals throughout the circuit, avoiding the reliability issues associated with multi-type signal conversion while preserving remote control functionality.
2Adaptability or versatility
If multiple types of signals are processed in the circuit, then remote control functionality is achieved, but conversion errors occur between different signal types
Solution Approach 1:
The patent removes the signal conversion components that cause accuracy degradation. By extracting the optocoupler and communication chip from the circuit, the system eliminates the source of conversion errors, achieving high signal processing accuracy by handling only voltage signals without type conversion.
Solution Approach 2:
The patent applies homogeneity by ensuring that all signal processing in the circuit operates on the same signal type (voltage signal). This uniformity eliminates the heterogeneity of processing multiple signal types, thereby preventing conversion errors and ensuring high manufacturing precision in signal handling.
3Adaptability or versatility
If a user needs to control multiple electrical devices, then comprehensive control coverage is achieved, but the user must approach each device individually which is inconvenient
Solution Approach 1:
The patent implements universality by designing a switch control circuit that can control multiple electrical devices through a single controller. The controller receives voltage signals and can issue control instructions to multiple devices, providing comprehensive control coverage while allowing the user to operate all devices from a single location, thereby improving ease of operation.
