Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If appearance-based comparison is used for object identification, then object features can be directly compared, but identification accuracy deteriorates due to shooting angle variations and excessive data processing time
Solution Approach 1:
The patent applies color changes by using light sources (LEDs) that emit different colors to represent different feature states of the object. The feature changing module changes the light source color according to feature signals, enabling angle-independent identification while maintaining high accuracy and speed.
Solution Approach 2:
The patent changes physical parameters by transitioning from static appearance comparison to dynamic light emission parameters. The system uses controllable light sources with varying intensity, color, and timing patterns to encode object features, eliminating the need for angle-based visual comparison and reducing processing time.
2Productivity
If barcode tags are used for object identification, then comparison can be performed using a rapid algorithm, but information capacity is insufficient and identification fails when the barcode image is not clear
Solution Approach 1:
The patent replaces traditional barcodes with color-changing light sources that can encode significantly more information through multiple color states, intensities, and temporal patterns. This maintains rapid identification while dramatically increasing information capacity beyond what static barcodes can provide.
Solution Approach 2:
The patent transitions from static barcode images to dynamic light emission patterns. The light sources can change colors and intensities over time, creating dynamic signals that are more robust to imaging conditions and carry richer information, eliminating the clarity dependency of traditional barcodes.
3Ease of operation
If dynamic tag technology with color changing is used, then object identification can be provided without high resolution images, but only simple numbered data can be transmitted and database reliance is required
Solution Approach 1:
The patent makes the light-based tag system universal by enabling it to perform multiple functions: providing simple identification numbers like traditional systems, transmitting rich feature information through multiple light sources and color patterns, and enabling two-way communication. This eliminates the need for database reliance while maintaining ease of operation.
Solution Approach 2:
The patent segments the information transmission by using multiple independent light sources that can be controlled individually. Each light source can carry specific feature information, allowing complex data to be transmitted through coordinated color and timing patterns without requiring high-resolution imaging or external databases.
4Measurement precision
If light signal emission sources are disposed in space for location determination, then tag location can be determined, but usable space range and precision are limited and occluded objects cannot be located
Solution Approach 1:
The patent replaces the mechanical/optical system of multiple spatially distributed light emitting units with an electronic control system. A single tag with controllable light sources uses wireless communication and signal processing to achieve precise location determination, eliminating the need for complex spatial configurations and working around occlusion issues through electronic signal coordination.
