Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a large number of operating keys are disposed to support various functions of advanced electronic equipment, then the functionality and versatility of the remote controller is improved, but the device complexity and number of components increases
Solution Approach 1:
The single operating part is designed to perform multiple functions including channel selection, volume control, and other remote control operations. By making one component universal, the patent eliminates the need for multiple separate keys while maintaining full functionality for controlling advanced electronic equipment with diverse features.
Solution Approach 2:
Multiple operating keys that would traditionally be separate components are merged into a single integrated operating part. This consolidation reduces the total number of components and simplifies the device structure while preserving all necessary control capabilities through different operational modes of the same component.
2Adaptability or versatility
If a large number of operating keys are disposed to support various functions, then the versatility is improved, but the ease of operation deteriorates due to complexity
Solution Approach 1:
The single operating part serves as a universal control interface for all remote control functions. Users interact with one component rather than navigating multiple keys, which simplifies the user interface and improves ease of operation while maintaining the ability to perform diverse functions through different operational modes.
3Adaptability or versatility
If a large number of switch contacts are provided corresponding to operating keys, then the functionality is improved, but the number of components and device complexity increases
Solution Approach 1:
Multiple switch contacts that would correspond to separate operating keys are merged into a single switch contact associated with the single operating part. This reduction in component quantity is achieved by consolidating the switching mechanism while maintaining functional diversity through different operational states and control signals generated by the same physical component.

AI summary
Provided is a remote controller in which a ring-shaped operating part is structured rotatable and capable of making rocking motion by pressing, a first remote-control signal responsive to rotation of the operating part allows sound volume adjustment, a second remote-control signal responsive to a switch signal supplied by pressing the operating part changes the function to channel selection, a third remote-control signal responsive to rotation of the operating part within a predetermined period of time allows channel selection. This structure can reduce the number of separate operating keys and allows a simple successive operation of the operating part to control a receiver.
