Rotatable Connection Stop Mechanism for Adjustable Angle Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotatable connections in stand apparatuses for medical technology devices in operating rooms lack flexibility in setting rotational angles, often limiting the action radius and requiring complex adjustments to achieve desired positional arrangements.
Innovation Solution
A rotatable connection with an adaptable stop mechanism that allows for the definition of multiple rotational angles or ranges by using a stop device with counter-stops, which can be axially displaced and rotated to set different rotational positions, eliminating the need for radial locking pins and enabling rotational ranges greater than 360°.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed stop mechanism is used to limit rotational angle, then the maximum rotational angle is controlled, but the freedom of movement and adaptability of the stand is reduced
Solution Approach 1:
The stop mechanism is designed to be adjustable rather than fixed. The stop can be positioned at different angular locations around the rotational path, allowing the rotational limit to be dynamically changed based on spatial requirements. This enables the stand to adapt its action radius while maintaining reliable angular control when needed.
Solution Approach 2:
The system allows changing the parameter of rotational angle limitation by repositioning the stop mechanism. The stop can be adjusted to different angular positions, effectively changing the maximum rotational angle parameter from a fixed value to an adjustable one, thus resolving the contradiction between control and adaptability.
2Measurement precision
If a radial locking pin is used to define rotational positions, then precise angular positioning is achieved, but the adjustment complexity and device complexity increase
Solution Approach 1:
The invention extracts the locking function from a complex radial locking pin mechanism and replaces it with a simpler stop mechanism that defines angular positions through axial placement. The stop mechanism achieves precise angular positioning without requiring radial insertion and locking operations, thereby reducing adjustment complexity while maintaining positioning precision.
Solution Approach 2:
The stop mechanism acts as an intermediary element between the rotational components, defining angular positions through its axial position rather than through complex radial locking. This intermediary approach simplifies the interaction between components while achieving the same positioning function.
3Ease of manufacture
If the stop mechanism is fixed during manufacturing, then the rotational angle limitation is predetermined, but the ability to adapt to different spatial situations is lost
Solution Approach 1:
The stop mechanism is designed with adjustability, allowing it to be repositioned after manufacturing. This dynamic capability enables the stand to adapt to different spatial situations in the operating room without requiring complex custom manufacturing for each application scenario.
Solution Approach 2:
The stop mechanism can be preliminarily positioned during manufacturing for standard applications, but retains the capability for subsequent adjustment. This preliminary positioning simplifies initial setup while preserving adaptability for non-standard situations.
