Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If continuous injection of abrasive particles is performed, then surface treatment effectiveness is maintained, but gas supply amount and electricity consumption increase
Solution Approach 1:
The patent applies periodic action by switching between continuous injection modes (first injection mode with high-pressure gas and abrasive particles, second injection mode with lower-pressure gas and fewer abrasive particles) based on the injection state. This periodic switching allows the system to maintain surface treatment effectiveness while reducing gas supply amount and electricity consumption during less intensive phases of the injection process.
2Manufacturing precision
If gas supply amount is increased to maintain injection effectiveness, then surface treatment quality is preserved, but electricity consumption increases
Solution Approach 1:
The patent applies dynamics by making the gas supply amount and injection mode adjustable rather than fixed. The control unit dynamically switches between first and second injection modes based on real-time injection state monitoring, allowing the system to optimize gas supply levels to match actual treatment needs, thereby maintaining surface treatment quality while minimizing electricity consumption.
Solution Approach 2:
The patent applies parameter changes by varying the pressure and flow rate of gas supply, as well as the amount of abrasive particles injected, based on the injection state. The control unit adjusts these parameters by switching between different injection modes, enabling the system to maintain optimal surface treatment quality while reducing energy consumption during phases where full power is not required.
3Use of energy by stationary object
If intermittent injection is implemented to reduce gas usage, then electricity consumption decreases, but surface treatment consistency may be compromised
Solution Approach 1:
The patent applies feedback by using the injection state (detected by the injection state detection unit) to control the switching between first and second injection modes. This feedback mechanism ensures that the system maintains sufficient surface treatment consistency by adjusting injection intensity based on real-time conditions, while still achieving reduced gas usage and lower electricity consumption through intermittent operation.
