Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hard-wired remote control solutions are used, then reliable control connection is achieved, but device complexity and installation cost increase
Solution Approach 1:
The patent replaces the mechanical hard-wired connection system with a wireless communication system. The remote control device uses wireless transmission (such as radio frequency or infrared) to send control signals to the equipment unit, eliminating the need for physical wiring between the remote control and the equipment. This substitution maintains reliable control connection while significantly reducing device complexity and installation cost.
2Ease of operation
If batteries are used in remote control, then operation independence is improved, but safety risks increase due to potential human error
Solution Approach 1:
The patent implements a pairing mechanism where the remote control device automatically identifies and pairs with the intended equipment unit through wireless communication. The system includes verification mechanisms that ensure the remote control is correctly paired with the appropriate equipment before allowing operation, preventing human error-related safety risks while maintaining operation independence.
3Measurement precision
If pairing mechanism is added to remote control, then correct unit identification is improved, but device complexity increases
Solution Approach 1:
The patent uses a universal pairing mechanism that can identify and pair with different equipment units through wireless communication. The remote control device incorporates a microcontroller and wireless transceiver that enable it to communicate with various equipment units using standard protocols, providing accurate unit identification without requiring complex device-specific pairing mechanisms for each equipment type.
4Ease of operation
If dongle storage location is provided in remote control, then operational readiness is improved, but device complexity increases
Solution Approach 1:
The patent incorporates a storage location for the dongle within the remote control device housing. The dongle can be inserted into and stored in a dedicated compartment or slot within the remote control body, allowing quick access and proper storage without requiring complex external storage solutions. This nesting approach maintains operational readiness while minimizing additional device complexity.
