Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional interaction modes (tapping, touching, pressing buttons, gestures) are used in electronic apparatuses with volume limitations, then the device structure remains simple, but the diversity and stability of human-computer interaction modes are limited

Engineering Contradiction:
Improvediversity of human-computer interaction modesVSAvoidinteraction mode complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The rotation control component enables a single physical component to perform multiple interaction functions including rotation detection, pressing detection, and positioning detection, allowing one component to replace what would traditionally require multiple separate controls (buttons, dials, touch zones), thereby increasing interaction diversity without proportionally increasing device complexity

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

Solution Approach 2:

The patent replaces traditional mechanical detection mechanisms with a magnetic detection system. Magnets are arranged on the rotation device, and a magnetic sensor detects changes in magnetic field strength to determine rotation position, pressing state, and positioning state, eliminating the need for complex mechanical switches, potentiometers, or multiple sensors

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

2Adaptability or versatility

If more interaction modes are added to electronic apparatuses, then user experience and functional operations are improved, but the device volume and structural complexity increase

Engineering Contradiction:
Improvefunctional operations diversityVSAvoiddevice volume
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent merges rotation control, pressing control, and positioning control into a single integrated rotation control component. The magnets and magnetic sensor combination allows one component to detect multiple types of user inputs (rotation direction, rotation position, pressing force, positioning state), reducing the overall space required compared to having separate control mechanisms for each function

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The rotation device is nested within a groove of the housing, with magnets arranged on the rotation device and the magnetic sensor positioned in the housing. This nested arrangement allows the detection system to be compactly integrated within the existing device structure without requiring additional external space

Inventive Principle:
Principle #7Nested doll (Nesting)

3Measurement precision

If magnetic parameter detection device is used to detect rotation positions, then rotation detection precision is improved, but the device complexity and manufacturing cost increase

Engineering Contradiction:
Improverotation position detection precisionVSAvoiddetection system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical position detection systems (such as encoders, potentiometers, or multiple optical sensors) with a simple magnetic field detection system. By arranging magnets at specific positions on the rotation device and using a magnetic sensor to detect magnetic field strength variations, the system achieves accurate position detection with minimal mechanical complexity

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

Solution Approach 2:

The patent uses changes in magnetic field strength as a parameter to encode position information. Different magnet arrangements (number, position, polarity) create distinct magnetic field patterns that the sensor can detect and translate into position information, providing precise detection through physical parameter changes rather than complex mechanical structures

Inventive Principle:
Principle #35Parameter changes
