Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-dimensional modeling apparatuses face challenges in achieving uniform heating of the modeling material on the stage, which affects the accuracy of the modeled object.
Innovation Solution
An attitude adjustment method is employed to adjust the position and orientation of a heating unit in the apparatus, involving fixing, measuring flatness, determining a planar position, and bringing the heating surface into contact with a parallel modeling surface to ensure uniform heating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the heating unit is fixed in position without attitude adjustment, then the device complexity is reduced, but the heating uniformity deteriorates
Solution Approach 1:
The heating unit is equipped with an attitude adjustment mechanism that allows dynamic modification of its orientation relative to the stage. This enables the heating unit to adapt its angle and position to compensate for surface irregularities and achieve uniform heating across the modeling material, resolving the contradiction between heating uniformity and device complexity.
Solution Approach 2:
The attitude adjustment mechanism changes the angular parameters (inclination and orientation) of the heating unit to optimize heating distribution. By adjusting these parameters, the system achieves uniform heating while maintaining a relatively simple overall device structure.
2Manufacturing precision
If the heating surface is kept parallel to the stage, then the device operation is simplified, but the manufacturing precision of the modeled object deteriorates
Solution Approach 1:
The heating unit incorporates adjustable attitude mechanisms that allow operators to easily modify the heating surface's orientation. This dynamic adjustment capability enables precise control over heating distribution to achieve high manufacturing precision while keeping the operation simple through intuitive positioning controls.
Solution Approach 2:
The system includes a detection unit that provides feedback on the relative position and orientation of the heating unit and stage. This feedback enables automatic or semi-automatic adjustment of the heating unit's attitude to achieve optimal heating conditions, thereby improving manufacturing precision without complicating the operation.
3Power
If the heating unit is positioned far from the stage, then the ease of operation is improved, but the heating efficiency deteriorates
Solution Approach 1:
The attitude adjustment mechanism allows the heating unit to be positioned close to the stage while maintaining operational ease through automated or semi-automated positioning controls. This dynamic positioning enables high heating efficiency through close proximity while keeping the operation simple through integrated control systems.

AI summary
An attitude adjustment method includes (a) fixing an attitude of a first heating unit by an attitude changing portion with a heating surface and a modeling surface or a jig provided in parallel to the modeling surface in contact in a first planar position, (b) measuring flatness of the heating surface by a planar sensor for measuring the flatness of the heating surface, (c) determining a second planar position where the heating surface and the modeling surface are brought into contact based on the measured flatness, and (d) bringing the heating surface and the modeling surface or the jig provided in parallel to the modeling surface into contact and fixing the attitude of the first heating unit by the attitude changing portion in the determined second planar position with a change of the attitude by the attitude changing portion allowed.
