Solution Overview
Problem
Existing additive manufacturing systems face challenges in aligning and maintaining the alignment of various modules, leading to operational faults and inefficiencies during the layer-by-layer construction of three-dimensional components.
Innovation Solution
The implementation of an attachment structure that aligns and supports the feed, take-up, and build modules through alignment pads and frames, ensuring precise positioning and tension control of the resin support, thereby minimizing misalignment and operational issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If modules are provided as separate components for additive manufacturing, then the system becomes more modular and easier to maintain, but alignment precision between modules deteriorates
Solution Approach 1:
Alignment pads serve as intermediary elements between separate modules (build module, feed module, take-up module). These pads provide standardized attachment surfaces that ensure precise relative positioning when modules are assembled, resolving the alignment precision issue while maintaining modularity
Solution Approach 2:
The attachment structure with alignment pads serves multiple functions: it provides mechanical support for modules, ensures precise alignment between modules, and maintains consistent spacing. This multi-functional design allows separate modules to be assembled with high precision without requiring custom-fit connections
2Area of stationary object
If modules are closely positioned for efficient space utilization, then the apparatus footprint is reduced, but alignment stability deteriorates
Solution Approach 1:
Alignment pads are pre-configured with specific geometric features and positioning tolerances before module assembly. This preliminary preparation ensures that when modules are installed, they automatically achieve stable alignment even in compact configurations, preventing alignment drift during operation
3Manufacturing precision
If rigid attachment structures are used to maintain module alignment, then alignment precision is improved, but adaptability for different configurations deteriorates
Solution Approach 1:
The attachment structure uses adjustable mounting mechanisms that allow the rigid alignment pads to be positioned and secured at different locations. This enables the system to maintain precise alignment through rigid connections while adapting to different module configurations and sizes
