Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing three-dimensional shaping systems face issues with shaping accuracy due to unsuitable execution of commands at specific positions on the shaping path, leading to deteriorated performance in forming three-dimensional shaped objects.
Innovation Solution
An information processing apparatus generates three-dimensional shaping data by acquiring and adjusting execution command information based on line segment length and direction information, ensuring precise command execution at optimal positions on the shaping path, thereby improving the shaping accuracy of the three-dimensional shaped object.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If commands are executed at standard positions on the shaping path, then the control process is simple, but the shaping accuracy deteriorates
Solution Approach 1:
The patent changes the parameter of command execution positioning from fixed standard positions to dynamically determined optimal positions based on shaping path geometry (line segment lengths and directions). This allows the system to adapt command execution positions to specific shaping requirements, improving shaping accuracy without requiring complex additional hardware or mechanisms.
Solution Approach 2:
The patent performs preliminary analysis of the shaping path geometry (calculating line segment lengths and directions) before generating the final execution commands. This preliminary action enables the system to pre-determine optimal command execution positions, ensuring high shaping accuracy while maintaining a relatively simple control structure by avoiding real-time complex calculations during execution.
2Manufacturing precision
If commands are executed at non-optimal positions, then the control process is simple, but the material deposition precision deteriorates
Solution Approach 1:
The patent modifies the command generation process to incorporate geometric parameters (line segment length and direction) into the determination of command execution positions. This parameter-based approach enables precise material deposition by aligning command execution with the geometric characteristics of the shaping path, while keeping the overall system structure relatively simple.
Solution Approach 2:
The patent implements a feedback mechanism where the shaping path geometry (line segment lengths and directions) is analyzed and used to adjust command execution positions. This feedback loop ensures that commands are executed at optimal positions that account for the specific geometric requirements of each segment, improving material deposition precision without requiring complex additional hardware.
3Manufacturing precision
If standard command execution positions are used, then the processing speed is high, but the shaping quality deteriorates
Solution Approach 1:
The patent performs preliminary analysis of the shaping path geometry (line segment lengths and directions) before generating execution commands. This advance preparation enables the system to determine optimal command execution positions in advance, ensuring high shaping quality while avoiding the need for complex real-time calculations during the actual shaping process, thus maintaining processing efficiency.
Solution Approach 2:
The patent transforms the command execution position determination from using fixed standard positions to using dynamically calculated optimal positions based on shaping path parameters. This parameter-based approach improves shaping quality by adapting to geometric requirements while keeping the data processing complexity manageable through efficient algorithms.
