Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional web setting devices are used to join webs and rotor blade shells, then the joining process can be completed, but the process is lengthy and complex with low precision and poor reproducibility
Solution Approach 1:
The alignment system is segmented into multiple alignment elements distributed on both the web and the web setting device. These alignment elements work in combination to achieve precise positioning through cumulative geometric constraints, breaking down the complex alignment task into manageable geometric relationships between multiple discrete elements.
Solution Approach 2:
The alignment elements are designed to automatically engage with each other when the web is placed on the web setting device. The complementary geometric shapes self-align through their inherent form, eliminating the need for complex adjustment mechanisms or operator intervention to achieve precise positioning.
2Productivity
If conventional web setting devices are used to join webs and rotor blade shells, then the joining process can be completed, but the process time is excessive
Solution Approach 1:
The alignment elements are pre-configured on both the web and the web setting device before the joining operation. The geometric shapes are designed in advance to automatically guide the web into the correct position upon contact, eliminating time-consuming adjustment and alignment operations during the actual joining process.
3Stability of the object's composition
If conventional web setting devices are used to join webs and rotor blade shells, then the joining can be performed, but the positioning is unstable and mechanically weak
Solution Approach 1:
The alignment system combines multiple alignment elements in a composite arrangement, where the web's alignment elements work together with the web setting device's alignment elements. This composite geometric constraint system provides both stable positioning and mechanical strength through the combined effect of multiple complementary shapes engaging simultaneously.
