Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If protective covers are made to cover the entireties of vertical buses, then insulation reliability is improved, but manufacturing complexity and assembly difficulty increase due to custom sizing and connection requirements
Solution Approach 1:
The protective cover is divided into a body portion and a connection portion as separate functional elements. The body portion covers the vertical bus, while the connection portion interfaces with the support. This segmentation allows the main protective function to be standardized while the connection interface adapts to different configurations.
Solution Approach 2:
The protective cover body is designed with a standardized structure that can accommodate different vertical bus lengths and configurations. The connection portion provides adaptive interfacing with the support, making the overall assembly universal rather than requiring custom-made covers for each specific application.
2Manufacturing precision
If protective covers are customized for different vertical bus lengths, then insulation precision is improved, but productivity decreases due to additional machining and assembly steps
Solution Approach 1:
The connection portion is designed to adapt to different positions and configurations of the vertical bus support. This dynamic adaptability allows a single standardized protective cover body to achieve precise insulation coverage regardless of the specific bus length or support position, eliminating the need for custom machining.
Solution Approach 2:
The design allows the effective coverage parameters of the protective cover to change based on the configuration of the vertical bus and support. The standardized body portion maintains consistent insulation precision while the connection portion adjusts to different dimensional parameters, achieving both precision and productivity.
3Strength
If connection portions are formed at distal ends of partition walls, then structural integrity is improved, but ease of manufacture deteriorates due to poor workability in connecting facing surfaces
Solution Approach 1:
The connection function is extracted from the main protective cover body and implemented through a separate connection portion. This allows the main body to focus on providing structural integrity and insulation, while the connection portion handles the interfacing function with simplified geometry that is easier to manufacture.
Solution Approach 2:
The connection portion acts as an intermediary element between the protective cover body and the support. It provides a dedicated interface that simplifies the connection process while maintaining the structural integrity of the overall assembly, resolving the conflict between strength and manufacturability.
