Pre-assembled Mounting Plate for Layer-wise Pattern Production
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for manufacturing patterns in layers, such as those used in rapid prototyping, face challenges with accuracy, cost, and time-intensive mounting and adjustment processes, particularly due to the deformation of mounting plates under weight stress and the need for extensive machining.
Innovation Solution
A device featuring a mounting plate with pre-mounted process-relevant positioning units and conveying devices, which is designed to minimize deformation and ensure accuracy by using a fully machined aluminum plate with cut-outs for the build platform and powder supply, along with a vertically displaceable and exchangeable build platform, and a guide system to manage weight forces and friction, allowing for easy assembly and reduced production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a mounting plate is used to support all process-relevant positioning units and conveying devices, then the device structure is simplified and assembly is easier, but the mounting plate deforms under weight stress causing accuracy loss
Solution Approach 1:
The device is divided into a permanent mounting plate and exchangeable mounting modules. Each module contains specific positioning units or conveying devices that can be independently mounted and removed. This segmentation allows the mounting plate structure to be optimized for rigidity while enabling flexible configuration of process units without reworking the entire plate.
Solution Approach 2:
The mounting plate is designed with specific structural parameters including thickness of 5-20mm, material selection (aluminum, steel, or composite), and reinforcement elements strategically positioned to withstand the weight of particulate material and equipment while maintaining surface flatness within narrow margins.
2Manufacturing precision
If the mounting plate is fully machined to ensure accuracy, then application precision is improved, but production cost and manufacturing time increase
Solution Approach 1:
The mounting plate is pre-machined only to the extent necessary to provide a stable, accurate base surface and precise mounting locations for the exchangeable modules. The full machining is not performed on the entire plate surface, but only on critical areas where positioning accuracy is required, reducing manufacturing cost while maintaining application precision.
Solution Approach 2:
The exchangeable mounting modules are designed with self-aligning and self-positioning features that allow them to be mounted on the pre-machined plate without requiring extensive machining of the entire plate. The modules themselves contain the precision machining needed for their specific functions, distributing the machining requirements across separate components.
3Stability of the object's composition
If guide elements are added to manage weight forces and friction, then structural stability is improved, but device complexity increases
Solution Approach 1:
The guide elements for managing weight forces and friction are integrated directly into the mounting plate structure rather than being separate components. The plate incorporates guide rails, support surfaces, and friction-reducing features as part of its basic structure, eliminating the need for additional standalone guide systems and reducing overall device complexity.
