Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If digital detection is used to determine points obtained, then detection capability is improved, but cost of installation, assembling, and maintenance becomes expensive
Solution Approach 1:
The patent replaces complex digital detection systems with a simple mechanical pressure detection mechanism. A pressure-sensitive component directly converts mechanical impact from BB shots into detectable signals, eliminating the need for expensive digital sensors, processors, and associated infrastructure while maintaining adequate detection capability for scoring purposes.
Solution Approach 2:
The invention employs inexpensive pressure detection components that can be easily replaced if needed, rather than investing in costly durable digital detection systems. The simple mechanical design uses affordable materials and components that reduce both initial installation cost and ongoing maintenance expenses.
2Measurement precision
If digital detection is used to determine points obtained, then detection capability is improved, but the device becomes complicated and not economic
Solution Approach 1:
The patent substitutes expensive digital detection equipment with a straightforward mechanical pressure sensing system. The impact detection is achieved through direct mechanical means that are simple to manufacture and maintain, making the overall system economic and suitable for widespread use in BB gun games.
Solution Approach 2:
The invention uses a simplified mechanical model of impact detection that captures the essential detection function without replicating the complexity of digital systems. The pressure-sensitive mechanism provides sufficient detection capability for scoring purposes while being much more economical to manufacture.
3Reliability
If existing target detection devices are used, then detection function is provided, but sensitivity is insufficient and disputes occur
Solution Approach 1:
The patent enhances detection sensitivity by optimizing the parameters of the pressure detection mechanism, such as the pressure threshold, spring constant, and mass of moving components. These parameter adjustments allow the system to detect even minor impacts from BB shots with high sensitivity, reducing false negatives and disputes while maintaining reliable detection function.
4Device complexity
If simple targets are used, then cost is reduced, but detection capability and sensitivity are inadequate
Solution Approach 1:
The patent achieves high detection sensitivity within a simple structural framework by using direct mechanical pressure detection. The design avoids complex digital subsystems while incorporating a well-tuned mechanical sensor that provides sufficient sensitivity for accurate shot detection, maintaining both simplicity and performance.

AI summary
A target pressure detection device (1) includes a housing (10), a resilient membrane (12), and a pressure detection unit (14). The housing (10) forms a chamber (102) having an open end and the housing (10) forms a through hole (104). The resilient membrane (12) is mounted to the housing (10) to cover and close the open end of the housing (10) so as to set the chamber (102) in an air-tight condition. The pressure detection unit (14) is mounted to the through hole (104) and forms therein an accommodation compartment (140) that movably receives therein a floating element (142). The accommodation compartment (140) receives therein a sensor (144). The sensor (144) can effectively detect a movement of the floating element (142) and thus the precision of detection of the target can be improved through detecting change of airflow.
