Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional touchscreen interface is used for parameter adjustment, then the device complexity is low, but the ease of operation and precision are insufficient

Engineering Contradiction:
Improveparameter adjustment intuitivenessVSAvoidinterface complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent creates a virtual copy of a physical spin wheel interface on the touchscreen display. This virtual spin wheel replicates the familiar tactile interaction patterns of physical dial controls, allowing users to adjust parameters by rotating their finger in a circular motion across the screen. The virtual interface mimics the behavior and feel of a physical spin wheel without requiring actual mechanical components, thus improving ease of operation while avoiding the complexity of mechanical integration.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces mechanical parameter adjustment mechanisms with a touch-based virtual spin wheel interface. Instead of using physical dials, knobs, or buttons that require mechanical movement and contact, the system uses capacitive touch sensing to detect rotational gestures on the screen. This substitution eliminates mechanical complexity while providing precise digital control through gesture recognition algorithms that track finger movement patterns.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If precise parameter control is implemented through traditional touch interfaces, then measurement precision can be improved, but the ease of operation deteriorates due to lack of intuitive control

Engineering Contradiction:
Improveparameter adjustment precisionVSAvoidcontrol intuitiveness
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent employs a circular spin wheel interface design where parameter adjustment is achieved through rotational finger gestures. The circular path provides natural ergonomic movement that follows the curvature of the user's finger, enabling precise control through continuous rotational motion. The system detects the angle and distance of rotation to determine parameter changes, offering both precision and intuitiveness through the circular interaction paradigm.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The virtual spin wheel interface incorporates visual feedback mechanisms that respond to user gestures in real-time. As users rotate their finger across the screen, the interface displays dynamic visual indicators showing the current parameter value, rotation direction, and progress toward target values. This immediate feedback loop enhances precision by allowing users to see the effect of their gestures while maintaining intuitive control through natural hand movements.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If a virtual spin wheel interface is added to enhance user experience, then ease of operation improves, but device complexity increases

Engineering Contradiction:
Improveparameter adjustment usabilityVSAvoidsoftware complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The virtual spin wheel interface is designed as a universal control mechanism that can adjust multiple different parameters across various applications and settings. Rather than creating separate control interfaces for each parameter type, the system uses the same spin wheel gesture paradigm throughout, allowing users to learn and master a single interaction pattern that works universally. This multi-functionality approach improves ease of operation while managing software complexity through code reuse and standardized gesture recognition.

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