Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a touch screen is used to provide diverse menu options, then the functionality of the mobile terminal is improved, but the ease of operation deteriorates due to small screen size making it difficult to select menu options
Solution Approach 1:
The front surface is divided into multiple functional regions: a first region with a touch screen for displaying menu options, and a second region with a touch keypad for easy input. This segmentation allows the touch screen to provide diverse functionality while the separate touch keypad region enables easy selection of menu options without the difficulties of using only a small touch screen.
2Adaptability or versatility
If more menu options and features are added to the mobile terminal, then the adaptability is improved, but the device complexity increases making the interface harder to use
Solution Approach 1:
By segmenting the input interface into a touch screen region for displaying diverse menu options and a separate touch keypad region for simplified input operations, the patent reduces interface complexity while maintaining adaptability. The touch keypad provides a simplified interaction model that does not require users to navigate complex on-screen interfaces.
3Ease of operation
If a touch screen is used for input, then the modern interface is improved, but the measurement precision deteriorates due to unrecognized input and accidental selection of multiple options
Solution Approach 1:
The patent segments the touch input system into two distinct regions: a touch screen region for displaying information and a separate touch keypad region for precise input. The touch keypad region uses a conductive sheet with specific touch sensing characteristics that provide more precise input recognition, reducing unrecognized inputs and accidental selections while maintaining a modern interface.
Solution Approach 2:
A conductive sheet is introduced as an intermediary element in the touch keypad region, positioned between the user's finger and the input sensors. This conductive sheet enhances touch detection precision by providing a consistent electrical interface that improves recognition accuracy and reduces false inputs.
