Solution Overview
Problem
Existing fluidic installations with anti-rotation elements struggle to adapt to various installation situations due to fixed configurations, which limits their versatility in different positions and shapes of flow channels.
Innovation Solution
A one-piece plate with pre-weakened bending lines allows for adjustable angular positions of its parts, enabling the anti-rotation element to be bent and configured to fit different positions and shapes of flow channels, ensuring secure attachment of the drive housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed configuration anti-rotation element is used, then the structure is simple and easy to manufacture, but it cannot adapt to different mounting situations and flow channel geometries
Solution Approach 1:
The anti-rotation element incorporates pre-weakened bending lines that allow the plate to be dynamically adjusted into different angular positions during installation. This enables the same component to adapt to various mounting situations and flow channel geometries without requiring multiple different parts, thus improving adaptability while maintaining structural simplicity.
Solution Approach 2:
The plate geometry is designed with pre-defined bending lines that allow changing the angular position of plate sections relative to each other. By varying the bending angle at these pre-weakened lines, the anti-rotation element can be configured to match different installation scenarios, including different drive positions and flow channel shapes, without increasing device complexity.
2Adaptability or versatility
If the anti-rotation element is made adjustable for different positions, then versatility improves, but manufacturing complexity increases
Solution Approach 1:
The plate is divided into sections by pre-weakened bending lines, creating distinct zones that can be independently positioned relative to each other. This segmentation allows the plate to be manufactured as a single piece with pre-formed features, while still enabling post-manufacturing adjustment through simple bending operations, thus maintaining ease of manufacture while achieving adjustability.
Solution Approach 2:
The bending lines are pre-formed during manufacturing, preparing the plate for future adjustment. This preliminary action during fabrication creates predetermined flexible zones that will later allow the plate to be bent into different configurations during installation, separating the manufacturing simplicity from the installation flexibility.
3Adaptability or versatility
If the plate sections are rigidly fixed, then structural strength is maintained, but adaptability to different geometries is lost
Solution Approach 1:
The plate transitions from a completely rigid structure to a semi-rigid structure with controlled flexibility at the bending lines. The pre-weakened bending lines provide localized flexibility for adjustment while the rest of the plate sections maintain their rigidity to ensure structural strength during operation, achieving both adaptability and strength.
Solution Approach 2:
Different parts of the plate have different mechanical properties: the bending lines are locally weakened to allow flexibility and adjustment, while the main plate sections remain rigid to provide structural strength. This local differentiation of quality allows the plate to be both adaptable during installation and strong during operation.
