Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional connection methods are used between electrical connection box and connection unit, then the connection work can be completed, but the workability and efficiency of connection work is insufficient
Solution Approach 1:
The protrusion is preliminarily formed on the connection unit and the pocket portion is preliminarily formed on the electrical connection box before connection work. These positioning portions are prepared in advance to guide the alignment and facilitate the connection process, improving workability without requiring complex adjustment operations during assembly.
Solution Approach 2:
The protrusion and pocket portion act as intermediary positioning elements between the connection unit and electrical connection box. The protrusion fits into the pocket portion to provide precise alignment, while the bolt serves as an intermediary fastening element that passes through both components to secure the connection, thereby improving ease of operation.
2Reliability
If precise alignment of connectors is required for reliable electrical connection, then connection reliability is improved, but the complexity of alignment operation increases
Solution Approach 1:
The protrusion and pocket portion are preliminarily formed with precise dimensions and positions before assembly. This preliminary precision work ensures that during connection, the alignment is achieved automatically through the fitting of these positioning portions, maintaining high reliability without requiring complex alignment operations or additional alignment devices.
Solution Approach 2:
The protrusion and pocket portion are designed to automatically align the connection unit and electrical connection box when brought together. The geometric fit of the protrusion into the pocket portion provides self-aligning functionality, ensuring precise connector alignment and reliable electrical connection without requiring external alignment tools or complex adjustment mechanisms.
3Stability of the object's composition
If temporary fixation during connection work is implemented, then connection stability is improved, but the number of components and assembly steps increases
Solution Approach 1:
The positioning function and fixation function are merged into a single integrated structure. The protrusion and pocket portion simultaneously provide alignment guidance and temporary fixation during connection work. The bolt that passes through both components serves dual purposes of securing the connection and maintaining stability, thereby achieving connection stability without significantly increasing component quantity or assembly complexity.
Solution Approach 2:
The bolt acts as an intermediary element that provides temporary fixation during connection work. It passes through the protrusion and pocket portion to secure the connection unit and electrical connection box in place, ensuring connection stability. This single intermediary fastening element achieves the fixation function without requiring multiple separate components or complex assembly steps.
