Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vibration-based tactile presentation is used, then force sensation is provided to the user, but diverse tactile expressions are limited
Solution Approach 1:
The patent applies parameter changes by transitioning from vibration-based tactile feedback to temperature-based feedback. The temperature sensation presentation unit changes the thermal parameter of the operation member to provide warm or cold sensations, thereby diversifying the tactile expressions beyond force sensation while maintaining effective user feedback.
Solution Approach 2:
The patent introduces a new dimension of tactile feedback by adding temperature sensation to the traditional force/vibration-based feedback. This dimensional expansion allows for more diverse tactile expressions including warm sensations, cold sensations, and pseudo-pain sensations, resolving the limitation of tactile expression diversity.
2Adaptability or versatility
If temperature sensation presentation unit is added to the operation member, then tactile expression diversity is improved, but device complexity increases
Solution Approach 1:
The patent merges the temperature sensation presentation unit with the operation member structure. The temperature presentation unit is integrated into the operation member, allowing it to provide thermal feedback at the same location where force feedback is provided, thereby minimizing structural complexity while achieving diverse tactile expressions.
Solution Approach 2:
The operation member is designed with multi-functionality, serving both as a force input device and a temperature feedback device. This universal design allows a single component to provide multiple types of tactile feedback (vibration and temperature), reducing the need for separate components and thereby limiting the increase in device complexity.
3Adaptability or versatility
If temperature control is synchronized with operation details, then user immersion is enhanced, but control system complexity increases
Solution Approach 1:
The patent implements feedback by synchronizing the temperature sensation presentation with the detected operation details. The control unit continuously monitors user operations and adjusts the temperature feedback in real-time based on the operation state, creating a responsive closed-loop system that enhances user immersion without requiring overly complex control architecture.
Solution Approach 2:
The temperature control system is designed to be dynamic, automatically adjusting the thermal feedback based on real-time operation detection. The temperature presentation unit can dynamically switch between different temperature states (warm, cold, neutral) according to the operation details, providing responsive tactile feedback while maintaining relatively simple control logic through predefined temperature mappings.
