Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a button structure with variable resistance elastic body is used, then the ability to reflect different degrees of operation is improved, but the device complexity increases
Solution Approach 1:
The patent changes the physical state of the elastic body from insulating to conductive through pressure-induced resistance variation. The elastic body's resistance parameter dynamically changes with applied force, enabling continuous signal generation that reflects different degrees of operation while maintaining a relatively simple button structure.
Solution Approach 2:
The patent uses a composite structure combining an elastic body with variable resistance characteristics and conductive materials. This composite approach allows the button to achieve both structural elasticity and electrical conductivity through material composition rather than complex mechanical mechanisms.
2Adaptability or versatility
If separate keyboards are used for ordinary and gaming purposes, then the functionality for each specific use is improved, but the loss of time and inconvenience increases
Solution Approach 1:
The patent makes a single keyboard universally applicable by integrating both ordinary typing functionality and gaming-specific pressure-sensitive control into one device. The button structure can operate in both binary on/off mode for general use and continuous pressure-sensitive mode for gaming, eliminating the need for separate keyboards.
Solution Approach 2:
The patent enables the keyboard to dynamically adapt its functionality based on the application. The same physical button can provide simple click detection for ordinary typing or detailed pressure level detection for gaming, with the system adjusting its response characteristics rather than requiring physical reconfiguration.
3Device complexity
If only two states of open and closed are used, then the device complexity is reduced, but the loss of information about different degrees of operation increases
Solution Approach 1:
The patent implements continuous feedback through the variable resistance elastic body that provides real-time information about the degree of button pressure. Instead of simple binary feedback, the system continuously monitors resistance changes to provide detailed information about force magnitude, enabling the computer to respond appropriately to different levels of user input.
