Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heat treatment devices face challenges in accurately conveying metal parts due to positional deviations of the tray and center of gravity, leading to improper alignment and conveyance in the intended linear direction.
Innovation Solution
A conveyance device with a cylinder mechanism featuring retractable rods and abutting members that contact different locations on the tray's outer peripheral surface, guided by rollers on a rail, ensuring accurate linear conveyance by adjusting for positional deviations through adjustable mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-point pressing mechanism is used to convey the tray, then the device structure is simple, but the conveyance precision deteriorates due to positional deviation of the tray and center of gravity
Solution Approach 1:
The single pressing point is segmented into multiple pressing points (first pressing point and second pressing point) positioned at different locations on the tray. This segmentation allows the system to compensate for positional deviations by distributing the pressing force across multiple points, thereby maintaining conveyance accuracy without significantly increasing structural complexity.
Solution Approach 2:
Different pressing points are strategically positioned at specific locations on the tray to address local variations in tray positioning and center of gravity. The first pressing point is positioned at a first location and the second pressing point at a second location, creating localized pressure zones that collectively ensure accurate conveyance despite deviations.
2Device complexity
If the tray is pressed at a fixed single location, then the mechanism is simple, but the conveyance stability deteriorates when center of gravity deviates from tray center
Solution Approach 1:
The pressing action is segmented into multiple discrete pressing points that can independently respond to tray positioning variations. This segmentation provides stability by distributing the mechanical load and creating multiple reference points for maintaining tray orientation during conveyance.
Solution Approach 2:
The system implicitly incorporates feedback through the geometric arrangement of multiple pressing points, where the relative positions of these points create a stable triangular or polygonal support structure that automatically compensates for center of gravity deviations without requiring active sensing or adjustment mechanisms.
