Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If display apparatuses with embedded circuits are used for visual information output, then information output capability is improved, but manufacturing convenience and control ease deteriorate
Solution Approach 1:
The patent extracts and removes the embedded circuits from the display apparatus, replacing the complex electronic information output system with a simple mechanical expression unit that can be directly controlled without complex circuitry, thus resolving the contradiction between information output capability and device complexity
Solution Approach 2:
The patent replaces the electronic/mechanical display system with a purely mechanical expression unit system that uses magnetic fields for control, eliminating the need for complex embedded circuits while maintaining information output functionality
2Adaptability or versatility
If tactile information output is provided for users with weakened visual senses, then accessibility is improved, but control stability and precision deteriorate
Solution Approach 1:
The patent incorporates feedback mechanisms where the expression unit's position and movement are precisely controlled through magnetic field interactions, providing stable and predictable tactile feedback that improves control stability while maintaining accessibility for users with visual impairments
Solution Approach 2:
The patent changes the control parameters from complex electronic signals to simple magnetic field strength variations, which provide more stable and predictable control characteristics for tactile output devices, thereby improving ease of operation
3Measurement precision
If driving force is increased for expression unit movement, then information output precision is improved, but interference and instability increase
Solution Approach 1:
The patent applies local quality by concentrating the magnetic field generation at specific locations around the expression unit, creating focused driving forces that achieve precise control without generating widespread interference, thus resolving the contradiction between precision and interference
Solution Approach 2:
The patent introduces magnetic fields as an intermediary between the control system and the expression unit, allowing precise force application without direct mechanical contact that would cause interference and instability
