Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If haptic signals are created considering device-specific characteristics to accurately reflect the creator's intention, then the haptic presentation accuracy is improved, but the work load on the creator increases
Solution Approach 1:
The patent introduces an intermediate representation signal as a mediator between the creator's original haptic signal and the device-specific output. This intermediate representation contains essential haptic information in a device-independent format, allowing automatic conversion to various device formats without requiring the creator to manually adapt signals for each device characteristics
Solution Approach 2:
The patent segments the haptic signal processing into distinct stages: creation of the intermediate representation signal containing essential haptic characteristics, and separate device-specific conversion processes. This segmentation allows the creator to focus on the essential haptic intent while device-specific adaptations are handled automatically through conversion processes
2Reliability
If haptic signals are adapted to different device characteristics to ensure consistent haptic experiences, then the haptic experience consistency is improved, but the signal processing complexity increases
Solution Approach 1:
The patent creates a universal intermediate representation signal format that can be converted to multiple device-specific formats. This universal format captures essential haptic characteristics in a way that can be systematically adapted to different device characteristics through automatic conversion processes, ensuring consistent haptic experiences across diverse output devices
Solution Approach 2:
The patent employs parameter changes to adapt the intermediate representation signal to different device characteristics. By systematically modifying signal parameters based on device-specific properties while preserving the essential haptic intent, the system achieves consistent haptic experiences across different devices without requiring complex manual processing
