Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors are used to determine the correct position of the blocking means relative to the vehicle tire, then the positioning accuracy is improved, but the device complexity and cost increase
Solution Approach 1:
The patent removes sensors from the blocking device entirely, extracting the measurement function from the device. Instead of using sensors to detect tire position, the system uses the blocking element's own mechanical contact with the tire to determine positioning, thereby simplifying the device while maintaining measurement capability
Solution Approach 2:
The blocking element serves dual functions: it both blocks the tire and determines the correct positioning through its own mechanical interaction with the tire. The system uses itself for measurement rather than requiring separate sensing components, reducing complexity while maintaining positioning accuracy
2Measurement precision
If sensors are used to determine the correct position of the blocking means, then the positioning accuracy is improved, but the reliability decreases due to sensor malfunction
Solution Approach 1:
By removing sensors from the system, the patent eliminates the reliability issues associated with sensor malfunction. The mechanical contact-based positioning method is inherently more reliable as it does not depend on electronic sensing components that can fail
Solution Approach 2:
The blocking element performs its own positioning function through direct mechanical contact with the tire, eliminating dependency on external sensing systems. This self-determination of position through mechanical interaction enhances reliability by removing vulnerable electronic components
3Reliability
If the blocking element is extended to contact the vehicle tire, then the blocking effectiveness is improved, but the risk of inappropriate contact with truck parts increases
Solution Approach 1:
The blocking element is designed to be dynamically adjustable in its extension, allowing it to adapt its position and contact force based on the specific tire geometry and blocking requirements. This dynamic adjustment ensures effective blocking while minimizing the risk of damage through controlled, adaptive contact
Solution Approach 2:
The system changes the extension parameter of the blocking element based on detected tire characteristics, adjusting the contact point and force to achieve effective blocking without causing damage. By varying the extension parameter according to specific conditions, the system optimizes both effectiveness and safety
4Adaptability or versatility
If height-adjusting means are added to accommodate different vehicle tire sizes, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The blocking device incorporates dynamic height adjustment capabilities that allow it to adapt to different tire sizes and vehicle types. This dynamic adjustability ensures versatility across various vehicles while the adjustment mechanism is integrated into the existing structure to minimize additional complexity
