Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional target with manual scoring is used, then the structure is simple, but the scoring process is inconvenient and complicated
Solution Approach 1:
The patent replaces manual mechanical scoring with an automated optical sensing system. The optical matrix sensor detects the position of shooting objects (arrows, darts) and automatically computes scores, eliminating the need for manual scoring while maintaining a relatively simple target structure.
Solution Approach 2:
The target system performs self-scoring through the optical matrix sensor and computation controller, which automatically detect hit positions and calculate scores without requiring external manual intervention, thereby improving ease of operation.
2Adaptability or versatility
If a conventional target with single pattern is used, then the structure is simple, but the training variety is limited
Solution Approach 1:
The patent implements dynamic target patterns that can be changed through software control. The computation controller can display different patterns (circles, squares, triangles, animal shapes) on the target surface, allowing the same physical target structure to provide multiple training modes and scenarios.
Solution Approach 2:
The target system is designed to perform multiple functions: it can display various patterns for different training purposes, provide automatic scoring, and support different shooting objects. This multi-functionality is achieved through the combination of the projection layer, optical matrix sensor, and computation controller.
3Loss of substance
If a conventional target with paper replacement is used, then the structure is simple, but the target paper consumption is high
Solution Approach 1:
The patent replaces physical paper targets with a digital projection system. The projection layer displays patterns electronically, and the optical matrix sensor detects hit positions, eliminating the need for physical paper replacement and reducing material consumption.
Solution Approach 2:
The target system changes the visual parameters of the target by projecting different patterns electronically rather than physically replacing paper. This allows infinite variations of target patterns without consuming additional physical materials.
4Extent of automation
If an electrical displacement sensing component is used, then the scoring is automated, but the device size becomes overly large
Solution Approach 1:
The patent replaces bulky electrical displacement sensing components with a compact optical matrix sensor system. The optical sensors and projection components can be integrated into a flat, space-efficient structure that maintains automated scoring functionality while reducing overall device volume.
5Extent of automation
If an electrical displacement sensing component is used, then the scoring is automated, but the structure becomes overly complicated
Solution Approach 1:
The patent replaces complex electrical displacement sensing mechanisms with a simpler optical sensing system. The optical matrix sensor uses light emission and detection principles that can be implemented with fewer mechanical moving parts and simpler structural requirements.
6Measurement precision
If conventional sensing points are used, then the structure is simple, but the sensing intensity is insufficient
Solution Approach 1:
The patent divides the sensing system into a matrix of multiple optical sensors arranged in rows and columns. This segmentation allows precise determination of hit positions by identifying which specific sensor elements detect the shooting object, thereby improving measurement precision.
Solution Approach 2:
The optical matrix sensor creates a digital copy of the target surface with multiple sensing points corresponding to different locations. This allows accurate detection and recording of hit positions without requiring physically complex sensing structures at each point.
