Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If haptic feedback systems use generic instructions without device-specific mapping, then the system complexity is reduced, but the haptic sensation consistency across different devices deteriorates
Solution Approach 1:
The patent applies parameter changes by transforming effect instructions into device-specific haptic instructions using transformation matrices that adjust parameters such as amplitude, frequency, and duration based on the physical characteristics of each haptic device. This resolves the contradiction by maintaining consistency through parameter adaptation rather than through complex device-specific programming.
Solution Approach 2:
The patent introduces an intermediary layer (the effect mapper with transformation matrices) between the generic effect instructions and the haptic device. This intermediary translates universal instructions into device-specific commands, achieving consistency without requiring complex device-specific logic in the original instructions.
2Reliability
If haptic feedback systems implement device-specific mapping instructions, then the haptic sensation consistency is improved, but the system complexity increases
Solution Approach 1:
The system uses parameter changes through transformation matrices that automatically adjust haptic instruction parameters based on device characteristics. This approach achieves consistency through mathematical transformation rather than complex conditional logic, reducing overall system complexity.
Solution Approach 2:
The patent implements preliminary action by pre-defining transformation matrices for different haptic device types. These matrices are prepared in advance and automatically applied based on device identification, eliminating the need for real-time complex calculations and reducing runtime system complexity.
3Adaptability or versatility
If haptic devices operate across multiple frequency ranges, then the versatility is improved, but the difficulty of mapping instructions accurately increases
Solution Approach 1:
The patent applies segmentation by dividing the frequency range into multiple bands and creating separate transformation matrices for each band. This allows accurate mapping for each frequency range while maintaining overall versatility, as each segmented matrix can be optimized for its specific frequency characteristics.
Solution Approach 2:
The system uses dynamics by implementing adaptive transformation matrices that can switch or blend between different frequency-specific mappings based on the operational requirements. This dynamic approach maintains accuracy across varying frequency ranges while preserving versatility.
