Centering Element Form-Locking Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing construction kits face difficulties in disassembling centering rings without damaging components, as the remaining ring in the recess is too small for secure removal by disassembly tools.
Innovation Solution
Incorporating a centering element with a form-locking means on its outer surface, such as orthogonal bores or a groove, allowing for easy extraction using a disassembly tool like a wedge, ensuring the centering element and recess remain undamaged.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If centering rings with small thickness are used to ensure high fit precision in assembly, then precise positional fixation is attained, but the remaining centering ring in the recess is too small to be securely picked up by a disassembly tool, making removal difficult and causing damage to components
Solution Approach 1:
The centering ring is segmented into two functional parts: a thin portion embedded in the recess for precise positional fixation, and a thicker outer portion extending beyond the recess for easy removal. This segmentation allows each part to fulfill its specific function optimally - the thin portion ensures precision while the thicker portion provides a secure grip for disassembly tools.
Solution Approach 2:
The thicker outer portion of the centering ring acts as an intermediary element that bridges the gap between the recess and the disassembly tool. It provides a sufficient engagement surface for the disassembly tool to securely pick up and remove the centering ring, while the thin embedded portion maintains the precise positional fixation function.
2Volume of moving object
If centering rings with small thickness are used to achieve compact design, then space efficiency is improved, but the remaining centering ring in the recess is too small to be securely picked up by a disassembly tool
Solution Approach 1:
The centering ring is segmented into a thin embedded portion for compact integration in the recess and a thicker outer portion for easy removal. This segmentation resolves the contradiction by allowing the ring to be compact when installed while providing sufficient material for tool engagement during disassembly.
Solution Approach 2:
The solution transitions from a uniform thin-ring design to a non-uniform design with varying thickness in different radial dimensions. The outer portion extends further radially outward, creating a dimensional variation that provides both compactness in the recess and sufficient engagement for removal tools.
