Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to fix the fan frame, then the fan frame can be securely fixed, but the fixing process becomes time-consuming and laborious
Solution Approach 1:
The fixing mechanism is segmented into modular components: a fixing base with through-holes, locking elements, and positioning troughs. This segmentation allows for rapid assembly without requiring multiple screws, as each component has a specific function that enables quick attachment while maintaining fixing strength.
Solution Approach 2:
The traditional screw-based mechanical fastening system is replaced with a locking element system that engages with positioning troughs. This substitution eliminates the need for screwdrivers and complex screw assembly, significantly reducing fixing time while maintaining secure attachment through the locking mechanism.
2Strength
If screws are used to fix the fan frame, then the fan frame can be securely fixed, but special tools are required for the fixing process
Solution Approach 1:
The screw-based fastening system requiring screwdrivers is replaced with a locking element system that can be manually inserted and engaged. This substitution eliminates the requirement for special tools, making the assembly process more accessible to users without specialized equipment while maintaining secure fixing strength.
Solution Approach 2:
The locking elements are designed to be self-contained and self-engaging with the positioning troughs. The fixing base with through-holes allows the locking elements to be inserted and secured without requiring external tools, enabling users to perform the assembly themselves easily while maintaining reliable fixing strength.
3Strength
If screws are used to fix the fan frame, then the fan frame can be securely fixed, but the screws and metallic parts generate noise due to vibration
Solution Approach 1:
Vibration-absorbing materials are introduced as intermediary elements between the locking elements and the positioning troughs. These materials act as dampers that absorb vibration and prevent the transmission of noise, while still allowing the locking mechanism to maintain secure fixing strength. The vibration-absorbing materials serve as a mediator that decouples the mechanical connection from noise generation.
4Loss of time
If the number of screws is reduced to shorten fixing time, then the fixing process becomes faster, but the fixing strength decreases causing fan vibration
Solution Approach 1:
The fixing system is segmented into multiple locking elements that can be independently engaged with the positioning troughs. This segmentation allows for distributed fixing points that collectively provide sufficient fixing strength without requiring a large number of screws, thereby reducing assembly time while maintaining security.
Solution Approach 2:
The screw-based fastening system is replaced with a locking element system that provides more efficient fixing per element. The locking elements engage directly with the positioning troughs, providing stronger and more reliable fixation with fewer components, thus reducing both fixing time and the total number of fastening elements required.
5Strength
If screws are used to fix the fan frame, then the fan frame can be securely fixed, but the screws have to be removed one by one for fan replacement which is inconvenient
Solution Approach 1:
The fixing system is segmented into removable locking elements that can be independently extracted from the positioning troughs. This segmentation allows for quick and easy fan replacement by simply removing the locking elements one by one, without requiring the removal of multiple screws, thereby improving user convenience while maintaining secure fixing strength during operation.
