Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a detonator explosion is used to achieve rapid deflation of the tire, then the tire burst simulation effect is improved, but the cost and convenience of transportation and use deteriorate
Solution Approach 1:
The patent extracts the core function of rapid deflation from the detonator system and implements it through a solenoid valve-controlled air release mechanism. The breakdown device punctures the tire to create a hole, and the solenoid valve rapidly releases the air, achieving the tire burst effect without using explosive detonators, thereby eliminating transportation restrictions and high costs.
Solution Approach 2:
The patent replaces the chemical explosion mechanism of detonators with a mechanical-pneumatic system consisting of a breakdown device (puncture mechanism), solenoid valve, and air storage tank. This substitution maintains the rapid deflation effect while improving ease of operation and reducing cost.
2Ease of operation
If a solenoid valve controlled rapid deflation device is used, then the convenience of use is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent designs the breakdown device with a universal mounting structure that can be installed on different tire types and vehicle models. The device integrates multiple functions (puncture, air release, retraction) into a single compact unit, reducing overall system complexity while maintaining ease of operation across different applications.
Solution Approach 2:
The patent employs a retractable breakdown device that can move between extended and retracted positions. This dynamic design allows the device to adapt to different operational states (installation, operation, storage) and reduces complexity by using a single adjustable structure rather than multiple fixed components.
3Ease of operation
If a tire burst device is placed on the road where the vehicle travels, then the ease of placement is improved, but the simulation accuracy deteriorates due to driver behavior changes
Solution Approach 1:
The patent uses a pre-tightening triggering device that positions the breakdown device in a pre-tightened state before the actual tire burst simulation. This preliminary positioning ensures the device is correctly aligned and ready to trigger at the exact desired moment, eliminating the need for road placement and preventing driver behavior changes that would affect simulation accuracy.
Solution Approach 2:
The patent incorporates a controller that monitors and controls the breakdown device operation. The feedback mechanism ensures the device triggers at the precise moment when the vehicle reaches the required speed, maintaining simulation accuracy without being influenced by driver reactions to road placement signs.
4Ease of manufacture
If the breakdown device is fixed in position, then the manufacturing simplicity is improved, but the adaptability to different vehicle speeds and conditions deteriorates
Solution Approach 1:
The patent implements a retractable breakdown device that can adjust its position between extended and retracted states. This dynamic capability allows the device to adapt to different vehicle speeds and operating conditions while maintaining relatively simple manufacturing through the use of a single adjustable mechanism rather than multiple fixed configurations.
