Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional input units like keyboards and mice are used, then data input precision is maintained, but portability and convenience deteriorate
Solution Approach 1:
The patent replaces mechanical input devices (keyboards, mice) with an optical-based input system. The wearable device uses optical signal transmission and sensing units to detect finger movements and gestures, converting them into input signals. This substitution eliminates the need for bulky mechanical components while maintaining input precision through optical detection of hand and finger positions.
Solution Approach 2:
The wearable device integrates multiple functions into a single portable unit. It combines optical signal transmission, optical signal sensing, data processing, and coordinate generation capabilities. This multi-functional integration allows the device to serve as both a portable platform and a precise input device, replacing multiple separate input units with one versatile wearable device.
2Measurement precision
If additional input units are used to maintain precision, then data input accuracy is improved, but device complexity increases
Solution Approach 1:
The patent merges the functions of multiple input units into a single wearable device. By integrating optical signal transmission, optical signal sensing, data processing, and coordinate generation units, the system consolidates what would traditionally require separate devices into one unified portable unit. This merging maintains input accuracy while reducing overall system complexity.
Solution Approach 2:
The wearable device creates a virtual representation of traditional input functionality through optical detection. Instead of using physical keyboards or mice, the system captures optical images of hand gestures and finger positions, then processes these images to generate equivalent input signals. This copying approach maintains input accuracy without requiring additional physical input devices.
3Ease of operation
If wearable device form factor is reduced for portability, then convenience is improved, but measurement precision may deteriorate
Solution Approach 1:
The patent uses optical detection methods instead of mechanical measurement systems. The optical signal sensing unit captures images of hand gestures, and the data processing unit extracts coordinate information through image processing algorithms. This optical approach enables precise measurement of hand and finger positions without requiring large mechanical components, thus maintaining precision while enabling a compact wearable form factor.
Solution Approach 2:
The system transitions from 2D surface detection to 3D coordinate generation through optical imaging. By capturing depth and spatial information through optical signals and processing them to generate three-dimensional coordinates, the device achieves precise spatial measurement capability in a compact form. This dimensional transformation allows accurate hand gesture tracking without requiring a large physical device.
