Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual installation method is used, then ease of operation is maintained, but productivity decreases and automation level cannot be increased
Solution Approach 1:
The device is divided into multiple independent functional modules: supply mechanism, positioning mechanism, expansion mechanism, and control system. Each module performs a specific function (valve storage, precise positioning, radial expansion, automated control), allowing the complex installation task to be broken down into manageable segments that can be independently optimized and maintained.
Solution Approach 2:
A robotic manipulator serves as an intermediary between the supply device and the wheel valve hole. The manipulator picks up valves from the supply mechanism and delivers them to the insertion point, decoupling the valve supply function from the insertion function and enabling automated high-precision operation without requiring direct human manipulation.
2Productivity
If automated manipulator is used, then productivity increases, but manufacturing precision requirements increase
Solution Approach 1:
The positioning mechanism pre-positions the valve at the correct angular orientation and radial position before the manipulator picks it up. The expansion mechanism is pre-configured with adjustable radial expansion capability to match different valve diameters. This preliminary preparation ensures that when the manipulator delivers the valve, precise insertion is achieved without requiring ultra-precise manipulator positioning.
Solution Approach 2:
The expansion mechanism provides dynamic adaptation to different valve sizes through radial expansion capability. The positioning mechanism can dynamically adjust angular positions to account for variations in wheel and valve dimensions. This dynamic adjustment capability maintains high insertion precision across different product variants while enabling automated high-speed operation.
3Manufacturing precision
If high-precision positioning is implemented, then manufacturing precision improves, but device complexity increases
Solution Approach 1:
The positioning mechanism uses self-aligning features such as tapered locators and cam-actuated locking mechanisms that automatically adjust to the valve and wheel geometry. The expansion mechanism self-adjusts its radial position based on the valve diameter through spring-loaded or hydraulically actuated flaps. This self-service capability achieves high precision without requiring complex external measurement and adjustment systems.

Implementation Method 1
due to the slope matching of the expanding flaps and the expanding core, the eight expanding flaps synchronously perform centripetal motion and centrifugal motion in the eight uniformly distributed T-shaped chutes formed in the internal cavities of the flange and the chassis, so that the eight expanding flaps implement high-precision synchronous expansion and shrinkage functions
Implementation Method 2
the oil cylinder overcomes the elastic forces of the springs to drive the connecting shaft C and the expanding core to move upwards
Implementation Method 3
the synchronous belt is respectively connected with the synchronous pulley A and the synchronous pulley B
