Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a complex articulated hook-type tool with multiple rotational degrees of freedom is used, then the tyre assembling-disassembling operation can be performed, but the device complexity increases and requires skilled operators
Solution Approach 1:
The tool is divided into two main functional parts: a simple tool-carrying arm for positioning and a plate-like member with hook-shaped end for engaging the tyre bead. This segmentation allows the complex articulation to be minimized while maintaining operational capability.
Solution Approach 2:
The complex control linkage and rotational mechanisms are extracted from the tool itself and replaced with a simpler structure that relies on the natural roto-translational movement of the plate-like member within the tool-carrying arm, reducing device complexity.
2Manufacturing precision
If manual control with complex linkages is used, then precise control of the tool is achieved, but the cost increases and skilled operators are required
Solution Approach 1:
The plate-like member is designed to automatically perform the necessary rotational and translational movements through its own geometry and interaction with the tyre bead, without requiring complex external control linkages or skilled operator intervention.
Solution Approach 2:
The tool utilizes dynamic roto-translational movement where the plate-like member naturally rotates and translates as it engages and moves the tyre bead, allowing precise control through motion dynamics rather than mechanical linkages.
3Productivity
If the tool is driven and held firmly in position by control linkage, then the tyre bead can be moved beyond the wheel rim edge, but the risk of damaging the wheel rim or tyre increases
Solution Approach 1:
The tool uses changes in the geometric parameters and orientation of the plate-like member during its roto-translational movement to smoothly guide the tyre bead over the wheel rim edge, reducing impact forces and damage risk.
Solution Approach 2:
The design inherently cushions the engagement by allowing the plate-like member to gradually rotate and translate into position, preventing sudden impacts that could damage the wheel rim or tyre during the assembling-disassembling operation.
4Extent of automation
If automated control is implemented, then skilled operators are not needed and manual errors are eliminated, but the device complexity increases
Solution Approach 1:
The need for complex automated control systems is extracted and eliminated by designing a tool that achieves its function through simple roto-translational movement, allowing automation with minimal complexity.
Solution Approach 2:
The tool design simplifies the complex articulated mechanisms of prior art by copying only the essential functional elements (the plate-like member with hook-shaped end) while eliminating unnecessary complexity through the roto-translational movement approach.
