Bushing with Integrated Spirit Level for Vertical Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for routing lines through concrete floor slabs lack effective alignment and stabilization, leading to potential misalignment and instability of the bushing, which can affect the accuracy and durability of the feedthrough.
Innovation Solution
A bushing system with a spirit level attachment, specifically a bubble level, is used to motivate installers to achieve optimal vertical alignment and stability by repeatedly checking and solidifying the bulk material around the bushing, combined with a multi-part structure and adjustable ground spike for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a spirit level is attached to the bushing, then the alignment precision and stability of the bushing during concreting is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The spirit level is integrated directly into the bushing structure, merging the alignment function with the feedthrough structure. This combination ensures that the alignment indicator is always available during installation and concreting processes, improving alignment precision without requiring separate alignment tools or procedures.
Solution Approach 2:
The spirit level is pre-attached to the bushing before installation, allowing alignment checks to be performed immediately during the concreting process. This preliminary preparation enables real-time monitoring and adjustment of bushing alignment, ensuring precision before the concrete sets.
2Reliability
If the spirit level is attached to the bushing, then the stability and alignment accuracy are improved, but additional costs and redundancy are introduced
Solution Approach 1:
The bushing structure itself provides the alignment function through the integrated spirit level, making the system self-sufficient. Installers can perform alignment checks directly on the bushing without needing separate alignment tools, improving reliability while actually reducing overall costs by eliminating the need for additional equipment.
3Manufacturing precision
If bulk material is repeatedly solidified around the floor duct, then the alignment and stability of the bushing are improved, but the installation time increases
Solution Approach 1:
The spirit level provides immediate visual feedback on bushing alignment status during the concreting process. This real-time feedback allows installers to make quick adjustments and know when alignment is achieved, reducing the number of iterative solidification cycles needed and optimizing installation time while maintaining precision.
