Solution Overview
Problem
Existing methods for producing bus ring plates for electrical conductor networks in aluminum production plants face limitations due to dimensional imprecision, internal stress, and material waste, which affect electrical conductivity and production costs.
Innovation Solution
A process involving the selection of a cast and annealed aluminum ingot of specific size, followed by precise sawing to produce panels with determined dimensions, and cutting according to a two-dimensional nested pattern to minimize waste and optimize planarity and thickness, ensuring high electrical conductivity and reduced stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If aluminium panels are made by rolling a massive cast block (ingot) in successive steps, then standard sizes can be produced, but dimensional imprecision in thickness and planarity occurs, and internal stress is imparted
Solution Approach 1:
The process segments the manufacturing steps: first casting a large ingot, then sawing it into multiple panels of precise dimensions, and finally cutting bus ring plates from these panels. This segmentation allows each step to be optimized independently, achieving both standardization and precision.
Solution Approach 2:
The ingot is sawn into panels with predetermined precise dimensions before the actual bus ring plate cutting operation. This preliminary action of creating precision panels first eliminates the dimensional imprecision that would otherwise be imparted during the final cutting stage.
2Ease of manufacture
If aluminium panels are made by rolling a massive cast block (ingot) in successive steps, then standard sizes can be produced, but internal stress is imparted which negatively affects later soldering
Solution Approach 1:
The manufacturing process is segmented into distinct stages: ingot casting, precision sawing into panels, and final plate cutting. This segmentation avoids the continuous rolling process that imparts internal stress, thereby improving soldering reliability.
Solution Approach 2:
The traditional mechanical rolling process is replaced with a sawing process to produce panels. Sawing does not impart the same level of internal stress as rolling, thus maintaining material integrity and soldering quality.
3Productivity
If nesting patterns are created for bus ring plates in standard-sized aluminium panels, then material utilization can be optimized, but aluminium loss occurs on unused edges of the panel
Solution Approach 1:
The process performs preliminary sawing of the ingot into panels with dimensions specifically calculated to minimize waste based on the nesting pattern requirements. This preliminary sizing action reduces the aluminium loss on unused edges compared to using fixed standard panel sizes.
Solution Approach 2:
The panel dimensions are changed from fixed standard sizes to customized sizes that precisely fit the nesting pattern of bus ring plates. This parameter change optimizes material utilization by eliminating excessive unused edges while maintaining production efficiency.
