Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wires are gathered into a twist to protect them during strong pendulum swing, then robustness of electrical connection is improved, but mass and dimensions of the flow valve increase
Solution Approach 1:
The patent transforms the traditional linear or planar wire arrangement into a three-dimensional conical spiral structure. This spatial transformation allows the wires to be distributed along the conical surface, maximizing the use of available space while minimizing the overall dimensions and mass of the protection structure.
Solution Approach 2:
The wires are nested within the conical spiral structure, with each wire following the spiral path. This nesting approach allows multiple wires to be organized in a compact manner, reducing the overall volume occupied by the wire bundle while maintaining robustness during pendulum swing.
2Reliability
If wires are gathered into a twist to protect them during strong pendulum swing, then robustness of electrical connection is improved, but dimensions of the flow valve increase
Solution Approach 1:
The conical spiral structure utilizes three-dimensional space efficiently, arranging wires along a conical surface rather than in a linear or planar configuration. This dimensional approach minimizes the bounding box dimensions while accommodating the necessary wire length and protection requirements.
Solution Approach 2:
The conical spiral introduces curvature to the wire arrangement, allowing the wires to follow a smooth spiral path along the cone surface. This curved configuration reduces sharp angles and stress concentrations while compacting the overall structure, thereby reducing dimensions without compromising robustness.
3Reliability
If a traditional twist structure is used, then electrical connection is protected, but interference between turns of the cone may occur during large displacement
Solution Approach 1:
The conical spiral structure provides different local characteristics along its length. The spacing between successive turns varies along the cone surface, with greater separation in regions where large displacement might cause interference. This local variation in spacing prevents turn-to-turn contact while maintaining the protective twist structure.
Solution Approach 2:
The conical spiral geometry is designed in advance to accommodate the expected range of pendulum displacement. By pre-configuring the wire paths along the cone surface with appropriate spacing, the structure prevents interference before it can occur during operation, eliminating the need for additional clearance mechanisms.
