Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional bus bar constructions with multiple separate components are used, then field distribution and component connection can be achieved, but the construction becomes complicated and manufacturing is difficult
Solution Approach 1:
The patent combines multiple separate components (bus bar sections, shield sections, and connecting elements) into a single integrated current conductor that can be produced by extrusion in one piece. This merging eliminates the need for complex assembly of multiple parts while maintaining the required field distribution and connection capabilities through the integrated design of the extruded structure.
Solution Approach 2:
The extruded current conductor performs multiple functions simultaneously: it provides current conduction through the central section, electromagnetic shielding through the shield sections, and component fixation through integrated fixing elements. This multi-functionality reduces the need for separate components and simplifies the overall construction while maintaining reliability.
2Reliability
If multiple separate components are assembled to form the current conductor, then field control and component fixation are achieved, but the manufacturing process becomes complicated
Solution Approach 1:
The patent merges the manufacturing of the central section, shield sections, and fixing elements into a single extrusion process. This one-step manufacturing approach produces the complete current conductor with all functional features integrated, eliminating complex assembly operations while ensuring consistent quality and reliability of field control and component fixation.
Solution Approach 2:
The extrusion process allows for precise control of the conductor's geometric parameters and material properties during manufacturing. By adjusting extrusion parameters, the design optimizes the cross-sectional shape, wall thickness, and fixing element geometry to achieve the required field control and mechanical fixation without requiring post-manufacturing adjustments or assembly.
3Reliability
If traditional multi-component bus bar systems are used, then electrical functionality is achieved, but production time and manufacturing complexity increase
Solution Approach 1:
The patent combines multiple manufacturing operations into a single extrusion process that produces the complete current conductor with all functional features. This eliminates the need for separate manufacturing and assembly steps for different components, significantly reducing production time while maintaining the required electrical functionality through the integrated design.
Solution Approach 2:
The extrusion process creates the final integrated product in one operation, with all features (conduction paths, shield sections, fixing elements) formed during the initial manufacturing step. This preliminary formation of all features eliminates subsequent assembly operations and reduces overall production time while ensuring the electrical functionality is built-in from the start.
