Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If cylindrical segmental parts with length equal to brush core length are used, then the brush core can be manufactured as a single piece, but manufacturing precision must be very high to prevent fitting problems during mounting
Solution Approach 1:
The brush core is divided into multiple cylindrical segmental parts that can be manufactured separately and then assembled together. This segmentation allows each part to be manufactured with standard precision while the zigzag support surfaces ensure proper fitting and alignment during assembly, eliminating the need for very high manufacturing precision on single long pieces.
2Length of moving object
If a very long element has to be extruded to achieve desired length, then the brush core can be produced in desired length, but production efficiency decreases and manufacturing becomes more difficult
Solution Approach 1:
Instead of extruding one very long cylindrical piece, the brush core is manufactured as multiple shorter segmental parts that are then assembled. This segmentation makes extrusion and manufacturing much easier while the zigzag support surfaces on the connecting lips ensure proper alignment and connection between segments, achieving the desired overall length without the difficulties of long single-piece manufacturing.
3Stability of the object's composition
If straight bend-proof ribs are used to connect inner and outer walls, then structural stability is improved, but flexibility for mounting and adaptability are reduced
Solution Approach 1:
The connection between inner and outer walls is achieved through multiple straight ribs distributed around the circumference, creating segmental stability. The ribs provide structural stability while the overall segmented design with removable segmental parts allows for flexible mounting and disassembly, combining both stability and adaptability.
Solution Approach 2:
The straight ribs serve multiple functions: they provide structural stability connecting the inner and outer walls, and they create a modular structure that enables flexible assembly and disassembly of the segmental parts. This multi-functionality achieves both structural stability and mounting flexibility.
4Ease of operation
If block-shaped parts with zigzag support surfaces are used for connection, then assembly is simplified and mounting becomes easier, but structural complexity increases
Solution Approach 1:
The connection structure is segmented into lips with zigzag support surfaces that engage between adjacent segmental parts. This segmentation simplifies assembly by providing self-aligning features that guide the parts together, while the modular nature of the segmented design actually reduces overall structural complexity compared to a monolithic structure.
Solution Approach 2:
The zigzag support surfaces on the lips provide curved, self-aligning contact surfaces that facilitate easy assembly by guiding the segmental parts into proper alignment. These curved surfaces simplify the mounting operation while the overall structure remains relatively simple through the use of standard geometric forms.
