Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting devices in operating rooms lack flexibility in setting rotational angles, often requiring fixed stops that limit movement and are difficult to adjust, especially in uncertain spatial situations.
Innovation Solution
A rotatable connection with an adjustable stop mechanism comprising a first part mounted torsion-proof on a spindle and a second part on a sleeve, featuring stop devices with counterstops that can be axially displaced and rotated to define various rotational angles, allowing for flexible positioning without the need for radial pins or screws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed stop is installed on the carrier to limit rotational angle, then the maximum rotational angle is controlled, but the freedom of movement of the mount is limited and the operating range 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 operating range to be dynamically adapted to different spatial situations while still maintaining reliable rotational angle control. This transforms a static limitation into a flexible control system.
Solution Approach 2:
The rotational parameters (angular position of stops) can be changed to adapt to different operating requirements. By modifying the position of the stop along the rotational path, the system can control the maximum rotational angle while preserving freedom of movement within the desired operating range, thus changing the parameter of angular limitation from fixed to variable.
2Reliability
If a stop is fixedly installed on the carrier, then rotational angle limitation is ensured, but the correct design and positioning of the stop causes difficulties in production when the usage location is not clarified
Solution Approach 1:
The stop mechanism allows for post-installation adjustment of the rotational angle limitation. Instead of requiring the stop position to be predetermined during manufacturing, the system enables the stop to be positioned at different angular locations after installation, based on the actual spatial situation. This eliminates the need for different stop positions for different locations.
Solution Approach 2:
The stop mechanism is pre-designed with the capability to be adjusted to different positions, but the actual positioning is performed later based on the specific application requirements. This preliminary preparation of adjustability allows the system to be manufactured in a standardized way while still accommodating location-specific requirements through subsequent adjustment.
3Adaptability or versatility
If the stop mechanism is made adjustable to adapt to different spatial situations, then the operating range is improved, but the device complexity increases
Solution Approach 1:
The stop mechanism is divided into separate components: a stop element that can be independently positioned and a mounting structure that allows for angular adjustment. This segmentation enables the stop position to be adjusted without redesigning the entire mechanism, achieving adaptability while keeping each individual component relatively simple.
Solution Approach 2:
The stop mechanism is designed with universal adjustability, allowing the same basic structure to serve multiple spatial configurations. By incorporating features that enable angular adjustment and repositioning, a single mechanism design can adapt to various operating ranges and spatial situations, reducing the need for multiple specialized designs.
