Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transportation of server racks without proper shock absorption and anti-vibration means leads to resonance and potential damage due to vibrations and impacts caused by road conditions.
Innovation Solution
A transport mechanism featuring a carrier plate with supporting assemblies that include cushion members with lower stiffness than the carrier plate, allowing for adjustable stiffness through filling members, and abutting members for enhanced support and wear resistance, effectively reducing vibrations and impacts during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid support structure is used for transporting server racks, then structural strength and stability are improved, but vibration and impact resistance deteriorate
Solution Approach 1:
The supporting assembly combines a rigid support plate with elastic cushion members, creating a composite structure that integrates both strength and vibration absorption capabilities. The support plate provides structural strength while the cushion members absorb vibrations and impacts, resolving the contradiction between rigidity and shock resistance.
Solution Approach 2:
The cushion members are strategically positioned at specific locations on the support plate where vibration and impact forces are most significant. This localized placement of elastic materials provides targeted shock absorption while maintaining overall structural integrity, addressing the contradiction between strength and vibration resistance.
2Object-affected harmful factors
If cushion members with low stiffness are used, then vibration absorption is improved, but load-bearing capacity deteriorates
Solution Approach 1:
The composite structure of rigid support plate and elastic cushion members allows the system to bear heavy loads through the rigid plate while simultaneously absorbing vibrations through the elastic cushions. The rigid component handles the load-bearing requirement while the elastic component addresses vibration absorption, resolving the contradiction between these two opposing requirements.
3Stability of the object's composition
If fixed stiffness support is used, then structural stability is improved, but adaptability to different server rack weights deteriorates
Solution Approach 1:
The elastic cushion members provide dynamic characteristics to the supporting assembly, allowing it to adapt its stiffness and vibration absorption characteristics based on the load. When server racks of different weights are placed on the support plate, the cushion members deform accordingly, maintaining structural stability while adapting to varying weight conditions.
Solution Approach 2:
The stiffness and vibration absorption properties of the supporting assembly change dynamically based on the applied load. The elastic cushion members exhibit different deformation characteristics under different weights, allowing the structure to maintain optimal performance across a range of server rack weights without requiring fixed, predetermined stiffness settings.
