Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stack manufacturing systems lack the necessary accuracy and productivity to efficiently integrate and shape multiple materials in a stacked state, particularly in arranging machining directions at right angles for enhanced precision and efficiency.
Innovation Solution
A stack manufacturing system with a stage unit, a vertically movable sandwiching member, and a press member that simultaneously presses and stamps out materials in a stacked state, where the machining units perform non-separating indentation machining with the material locked to scrap portions, and the machining directions are arranged at right angles or radially about the stage unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional progressive feeding stacking is used, then manufacturing process is simple, but manufacturing precision and productivity are insufficient
Solution Approach 1:
The patent combines multiple machining units (first machining unit and second machining unit) and stacking functions into a single integrated manufacturing system. The press member simultaneously presses and integrally stamps out multiple materials in a stacked state, merging cutting, shaping, and stacking operations into one coordinated process, thereby improving manufacturing precision while maintaining reasonable system complexity.
Solution Approach 2:
The patent introduces orthogonal arrangement of machining directions (first machining unit and second machining unit at right angles) to add spatial dimensionality to the manufacturing process. This multi-directional machining approach enables higher precision stacking by processing materials from different orientations simultaneously, resolving the contradiction between precision and complexity.
2Productivity
If simultaneous pressing and integral stamping is implemented, then productivity increases, but device complexity increases
Solution Approach 1:
The press member is designed to simultaneously perform pressing and integral stamping of multiple materials in a stacked state. By combining these operations into a single pressing action rather than sequential steps, the system achieves higher productivity without proportionally increasing device complexity.
Solution Approach 2:
The materials to be stacked are pre-positioned and locked to scrap portions before the pressing operation. This preliminary arrangement ensures that when the press member stamps out the components, they are already in the correct positions and orientations, enabling simultaneous processing without requiring complex real-time control mechanisms.
3Manufacturing precision
If orthogonal machining directions are used, then manufacturing precision improves, but space requirements increase
Solution Approach 1:
The patent utilizes three-dimensional space by arranging the first and second machining units at right angles to each other. This orthogonal configuration allows both machining directions to operate within a compact footprint by exploiting vertical and horizontal dimensions simultaneously, achieving high precision without excessive space consumption.
Solution Approach 2:
The machining units and material flow paths are arranged in a nested or overlapping configuration where the first and second machining operations share common space around the stage unit. This compact arrangement enables orthogonal machining directions while minimizing the overall machine footprint.
