Ceiling Flange Mounting for Adjustable Operating Theatre Stand Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting devices for tripods in operating rooms require costly structural adjustments and lack simplicity in height adjustment, especially when the exact height of the ceiling is unknown, and they often struggle with high load-bearing capacity and flexibility.
Innovation Solution
A mounting device with a tubular design featuring radially protruding fastening sections that can be coupled to a ceiling flange at various points, allowing for adjustable height positions without penetrating the tubular body, ensuring robustness and high load-bearing capacity, and enabling easy assembly and adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the ceiling flange is rigidly fixed at a single mounting position, then the structural stability and load-bearing capacity are improved, but the adaptability to different ceiling heights is worsened
Solution Approach 1:
The mounting device is divided into two main components: a ceiling flange and a mounting device body connected via a connecting component (spindle). The ceiling flange can be mounted at different positions along the mounting axis by adjusting the length of the connecting component, allowing the system to adapt to various ceiling heights while maintaining structural integrity through the rigid connection between components
Solution Approach 2:
The mounting device incorporates an adjustable connecting component (spindle) that allows dynamic adjustment of the distance between the ceiling flange and the mounting device body. This enables the system to adapt to different ceiling heights by changing the effective length of the connecting component, while the rigid fixed connections at each end maintain the required load-bearing capacity
2Adaptability or versatility
If the mounting device is designed with multiple adjustment mechanisms, then the adaptability to different heights is improved, but the device complexity increases
Solution Approach 1:
The height adjustment function is extracted from the main mounting device body and implemented through a separate, adjustable connecting component (spindle). This allows the mounting device body to remain simple and rigid while the adjustment capability is provided by the removable connecting component, reducing the overall device complexity
Solution Approach 2:
The connecting component serves multiple functions: it connects the ceiling flange to the mounting device body, provides height adjustment capability, and maintains structural rigidity for load-bearing. This multi-functionality reduces the need for separate adjustment mechanisms, keeping the device design simple
3Manufacturing precision
If the mounting device requires precise drilling for bolt holes at specific positions, then the manufacturing precision is improved, but the ease of manufacture and installation is worsened
Solution Approach 1:
The connecting component is designed with pre-defined hole positions and geometries that accommodate standard mounting requirements. This preliminary design allows installers to use standard drilling and mounting procedures without requiring precise custom hole positioning, simplifying the installation process while maintaining adequate manufacturing precision
