Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If haptic presentation is performed without considering contact body variations, then the system structure remains simple, but haptic perception accuracy deteriorates due to variations in contact bodies and attachments

Engineering Contradiction:
Improvehaptic perception accuracyVSAvoidsystem structure
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system acquires contact body information (mass, gripping force) and uses this feedback to dynamically adjust haptic output signals. The haptic control unit modifies vibration amplitude and frequency based on detected contact body characteristics, creating a closed-loop system that adapts to varying conditions while maintaining haptic perception accuracy.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The haptic presentation system transitions from a static configuration to a dynamic one by continuously adjusting vibration parameters (amplitude, frequency) based on real-time contact body information. This dynamic adaptation allows the system to maintain optimal haptic perception across different contact bodies and attachment configurations.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If attachments are mounted on the haptic presentation apparatus, then functionality is enhanced, but vibration characteristics change causing haptic perception accuracy to deteriorate

Engineering Contradiction:

Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system performs preliminary acquisition of contact body information (mass, gripping force) before generating haptic output signals. By knowing the contact body characteristics in advance, the haptic control unit can pre-adjust vibration parameters to compensate for the effects of attachments, ensuring accurate haptic perception from the start.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system changes vibration parameters (amplitude, frequency) based on detected contact body characteristics and attachment mass. The haptic control unit dynamically adjusts these parameters to compensate for the inertial effects introduced by attachments, maintaining consistent haptic perception accuracy across different attachment configurations.

Inventive Principle:
Principle #35Parameter changes

3Measurement precision

If vibration amplitude and frequency are not adjusted based on contact body information, then control complexity is reduced, but haptic perception intensity varies due to contact body variations

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The haptic control unit uses contact body information (mass, gripping force) as feedback to dynamically adjust vibration amplitude and frequency. This feedback mechanism ensures consistent haptic perception intensity by compensating for variations in contact body characteristics, while the adjustment logic maintains manageable control complexity.

Inventive Principle:
Principle #23Feedback
