Adjustable Stop Mechanism for Rotatable Joint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stop mechanisms in rotatable connections or pivot joints are fixed and do not allow for adjustable range of rotational movement, limiting their adaptability to specific spatial or application requirements.
Innovation Solution
An adjustable stop mechanism comprising a first and second part with abutment members that can be selectively positioned around the joint members to define and set the range of rotation, utilizing detent mechanisms for registered interconnection to fix the stops at various positions, allowing for flexible adjustment of the rotational limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed stops are used in a rotatable connection, then the structure is simple and reliable, but the adaptability to different spatial parameters and application requirements is limited
Solution Approach 1:
The stop mechanism is divided into multiple independent stops (first stop, second stop, third stop) that can be selectively positioned along the shaft. Each stop can be independently adjusted to define different limits of rotation, allowing the system to adapt to various spatial requirements without requiring a completely different mechanism for each application.
Solution Approach 2:
The stop mechanism transitions from a fixed configuration to a dynamically adjustable one. The stops can be selectively positioned at different locations along the shaft and fixed in place, enabling the range of rotation to be modified based on specific installation requirements while maintaining structural reliability.
2Ease of operation
If fixed stops are used in a pivot connection, then the manufacturing is simple, but the ease of operation for adjusting range of movement is poor
Solution Approach 1:
The stop mechanism uses multiple separable stops that can be independently positioned and fixed. This segmentation allows for easy adjustment of the rotation range by simply repositioning individual stops along the shaft, significantly improving ease of operation while maintaining relatively simple manufacturing processes.
Solution Approach 2:
Multiple stop positions are pre-configured along the shaft during manufacturing, allowing the user to easily select and fix the appropriate stop position during installation or adjustment. This preliminary preparation of multiple possible positions simplifies the adjustment process without complicating the overall manufacturing.
