Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the device is fixed on the central shaft, then the structure is stable, but the adaptability to different vehicle models deteriorates
Solution Approach 1:
The patent employs a dynamic fixing mechanism that can adapt its configuration based on the vehicle model. The fixing module includes adjustable components that can be repositioned or reconfigured to suit different wheel hub sizes and shapes, allowing the device to maintain stable attachment across various vehicle types without being permanently fixed to a central shaft.
Solution Approach 2:
The fixing module is designed with universal mounting capabilities that can accommodate different vehicle models. It includes multiple mounting positions and adjustable fastening mechanisms that can be configured for various wheel hub specifications, making the device adaptable to different vehicle types while maintaining stable fixation during operation.
2Device complexity
If passive components are used, then the device structure is simple, but the controllability deteriorates
Solution Approach 1:
The patent incorporates a feedback control system where sensors continuously monitor tire pressure and provide real-time data to the control module. The control module processes this information and automatically adjusts the inflation process, creating a closed-loop system that maintains precise controllability while managing device complexity through intelligent control algorithms.
Solution Approach 2:
The device includes automatic detection and control functions that enable self-service operation. The sensing module automatically detects tire pressure conditions, and the control module autonomously manages the inflation process without requiring constant manual intervention, thereby maintaining controllability while reducing operational complexity.
3Device complexity
If manual separation is required after full inflation, then the control system is simple, but the operation time increases
Solution Approach 1:
The control module receives continuous feedback from the sensing module regarding tire pressure status. When the target pressure is reached, the system automatically detects this condition and triggers the separation mechanism, eliminating the need for manual intervention and reducing the time required to complete the inflation process.
Solution Approach 2:
The device incorporates automatic separation functionality that activates when inflation is complete. The control module autonomously manages the entire process from inflation to separation, freeing the driver from manual operations and reducing overall operation time while maintaining a relatively simple control system architecture.
4Adaptability or versatility
If the wheel contact shape changes, then the tire adapts to road conditions, but the travel stability deteriorates
Solution Approach 1:
The sensing module continuously monitors tire pressure and provides real-time feedback to the control module. This allows the system to detect and compensate for changes in wheel contact shape caused by road conditions, maintaining travel stability by adjusting inflation parameters dynamically while still allowing necessary adaptation to road surfaces.
Solution Approach 2:
The control module dynamically adjusts inflation parameters based on feedback from the sensing module. When road conditions cause changes in wheel contact shape, the system modifies pressure parameters in real-time to maintain optimal balance between tire adaptation to terrain and travel stability, preventing excessive deformation that would compromise stability.
