Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional cabinets are assembled with side brace members using screws with planar contact, then assembly is simple, but load capacity and stability are low
Solution Approach 1:
The side brace member is divided into multiple segments with connecting structures that can flexibly connect to the frame. This segmentation allows the side brace member to better adapt to the frame structure while maintaining connection strength, resolving the contradiction between assembly simplicity and load capacity.
Solution Approach 2:
The connecting structure employs an elastic fastening mechanism that allows dynamic adjustment and absorption of forces. The elastic component enables the connection to accommodate movements and loads, significantly improving both the load capacity and stability while maintaining ease of assembly through the same connecting structure.
2Reliability
If side panels are installed between cabinets using modified custom structures, then airflow control is improved, but versatility and flexibility are reduced
Solution Approach 1:
The connecting structure serves multiple functions: it provides structural connection, enables elastic fastening for stability, and facilitates easy installation and removal of side panels. This multi-functionality allows the same structure to achieve reliable airflow control through side panels while maintaining versatility for different application scenarios and easy cabinet reconfiguration.
3Adaptability or versatility
If additional accessories are installed for power distribution and cable management, then functionality is improved, but workload and costs increase
Solution Approach 1:
The connecting structure is integrated with power distribution and cable management functions. The same connecting components that provide structural attachment also incorporate pathways for cable routing and power distribution, eliminating the need for separate accessories and reducing both workload and costs while maintaining enhanced functionality.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The modular frame structure significantly enhances the stability and load capacity of the enclosure system, providing improved resistance to external loads and facilitating efficient cable management and power distribution, thus addressing the limitations of conventional systems while reducing costs and complexity.
Implementation Method 1
the fastening surface is distanced from the end edges of the side brace members, the fastening distance and thus the fastening force are adaptable. This elastic fastening structure along with frictional contact between surfaces behaves like a viscoelastic system which offers excellent resistance to impact forces or dynamic loads by absorbing energy
Implementation Method 2
This elastic fastening structure along with frictional contact between surfaces behaves like a viscoelastic system which offers excellent resistance to impact forces or dynamic loads by absorbing energy
Implementation Method 3
tightening the fastener results in higher internal tension force inside the fastener, and the fastener in return applies a higher contacting force on the fastening surface
Implementation Method 4
Because the side brace member has a fastening structure on both ends, it is under high compressional forces. These compressional forces reinforce the attachment of side brace member to the pillars of the frames
