Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vibration elements are added to enable haptic recognition during hover touches, then user interaction capability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple vibration generators and speakers into a single integrated vibration element. This unified structure performs both haptic feedback generation and sound output functions, thereby improving hover touch recognition capability while avoiding the increase in device complexity that would result from adding separate components.
Solution Approach 2:
The vibration element is designed as a multi-functional component that simultaneously provides haptic feedback for hover touch recognition and generates audible sound. This universal design allows one component to fulfill multiple roles, enhancing user interaction capability without proportionally increasing device complexity.
2Adaptability or versatility
If separate vibration generators and speakers are used for haptic feedback and sound output, then functional versatility is improved, but device complexity and component quantity increase
Solution Approach 1:
The patent integrates the vibration generator and speaker into a single unified vibration element. This merging of components achieves both haptic feedback and sound output functionality while reducing the total number of components and simplifying the overall device structure.
Solution Approach 2:
The vibration element is designed as a universal component capable of performing both haptic feedback generation and audible sound output. This multi-functional design eliminates the need for separate dedicated components, thereby maintaining functional versatility while reducing device complexity.
