Rotating Bushing for Tubular Feed-Throughs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing feedthrough solutions for guiding tubular elements through sloping roofs are costly and require individual, specially adapted components for different roof inclinations, limiting their versatility and adaptability.
Innovation Solution
A three-part bushing system where the lower bearing surface of the intermediate piece rotates on the upper bearing surface of the base element, allowing for infinite adjustment to various inclinations, with the intermediate and end pieces capable of independent rotation to align the common axis, enabling precise alignment and adaptation to different roof pitches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If individual, specially adapted components are produced for different roof inclinations, then the alignment precision for specific roof pitches is improved, but the manufacturing cost and device complexity increase
Solution Approach 1:
The bushing is divided into multiple independently rotatable segments (base element, intermediate pieces, end piece) that can be adjusted relative to each other. This segmentation allows each part to contribute to the overall alignment adjustment, enabling a single standardized bushing design to adapt to various roof inclinations without requiring multiple specialized components.
Solution Approach 2:
The bushing incorporates rotatable elements with bearing surfaces that can be dynamically adjusted to different angular positions. The intermediate pieces and end piece can rotate independently on their bearing surfaces, allowing the bushing to dynamically adapt its orientation to match different roof pitches while maintaining precise alignment of the common axis.
2Adaptability or versatility
If a single standardized bushing is used for different areas, then the ease of manufacture and adaptability are improved, but the alignment precision for specific inclinations may be compromised
Solution Approach 1:
The rotatable intermediate pieces and end piece allow the standardized bushing to dynamically adjust its orientation. By rotating these elements to specific angles, the bushing can precisely align with different roof inclinations while maintaining a common vertical axis, thus achieving both versatility and precision.
Solution Approach 2:
The bushing allows for parameter changes in the angular orientation of its components. The bearing surfaces are designed with specific inclination angles that can be combined through rotation to achieve the desired overall alignment for different roof pitches, maintaining precision across various applications.
3Adaptability or versatility
If multiple rotatable elements are introduced for adjustment, then the adaptability to different roof pitches is improved, but the device complexity increases
Solution Approach 1:
The bushing is segmented into modular components (base element, intermediate pieces, end piece) that can be independently manufactured and assembled. This segmentation enables each component to be optimized for its specific function while contributing to the overall adaptability, balancing complexity with functionality.
Solution Approach 2:
Each rotatable element serves multiple functions: providing structural support, enabling angular adjustment, and facilitating rotation. This multi-functionality reduces the need for additional specialized components, thereby limiting the increase in device complexity while maintaining high adaptability.
