Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If pressure sensors are added to edge areas, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The sensor unit is divided into multiple pressure sensors positioned at different edge areas (first edge area, second edge area, third edge area, fourth edge area), each capable of detecting pressure inputs independently. This segmentation allows the system to provide differentiated input control for different edge regions while maintaining a modular structure that manages complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pressure sensors serve multiple functions: detecting tap inputs, swipe inputs, and squeeze inputs across different edge areas. The same sensor type (pressure sensor) is used throughout all edge areas, providing universal input detection capability while reducing the need for different sensor types and simplifying the overall system architecture.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple pressure sensors are disposed in edge areas, then adaptability is improved, but device complexity increases

Engineering Contradiction:
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system dynamically responds to different pressure input types (tap, swipe, squeeze) detected by the pressure sensors, adapting its operation based on the nature and location of the input. The control unit interprets sensor signals differently based on pressure magnitude, duration, and position, providing versatile input methods without requiring separate hardware for each input type.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system uses parameter changes in pressure detection (pressure threshold, duration threshold, position coordinates) to differentiate between various input types. By monitoring changes in pressure parameters over time and space, the system achieves high adaptability in recognizing different user intentions without adding physical complexity.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If pressure sensors detect input signals, then ease of operation is improved, but reliability may worsen due to potential malfunctions

Engineering Contradiction:
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The control unit continuously monitors signals from the pressure sensors and provides haptic feedback through the haptic module based on detected inputs. This feedback mechanism allows the system to confirm proper sensor operation and provide intuitive response to user inputs, while also enabling detection of abnormal sensor behavior that could indicate malfunction or interference.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The pressure sensor system is designed to automatically distinguish between valid user inputs and potential interference or malfunctions by analyzing pressure patterns, duration, and position. The system self-regulates by comparing detected signals against predefined thresholds and patterns, reducing the need for external intervention and maintaining reliability while enabling intuitive operation.

Inventive Principle:
Principle #25Self-service
