Hollow Section Extrusion Chassis for Rigid Equipment Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic racks and mounting chassis for sensitive equipment lack sufficient rigidity and secure fastening mechanisms, leading to potential movement and instability during transportation and use.
Innovation Solution
A modular electronic rack and mounting chassis system utilizing hollow section extrusions for chassis members and interlocking connections, combined with anti-vibration mounts and blind fasteners, provides a self-supporting structure that maintains rigidity and secure fastening, preventing movement except along the longitudinal axis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional mounting chassis are used, then the structure is simple, but the rigidity and stability are insufficient
Solution Approach 1:
The chassis members utilize composite construction combining hollow section extrusions with internal reinforcement structures. The hollow sections provide structural rigidity while incorporating internal mounting channels and features that add functional complexity without compromising the overall rigidity-strength ratio.
Solution Approach 2:
The mounting chassis is divided into modular chassis members that can be individually assembled. Each member is a hollow section extrusion with specific structural features, allowing the overall structure to achieve high rigidity through precise modular assembly rather than requiring a monolithic complex structure.
2Reliability
If simple fastening mechanisms are used, then the device complexity is low, but the security and stability during transportation deteriorates
Solution Approach 1:
The hollow section chassis members are pre-formed with integrated mounting channels, recesses, and attachment features during the extrusion process. This preliminary structuring eliminates the need for complex secondary fastening mechanisms, as the security features are built into the base structure itself.
Solution Approach 2:
The hollow section structure acts as an intermediary element between the mounting equipment and the chassis members. The internal channels and recesses of the hollow sections provide intermediate attachment points that secure equipment without requiring complex external fastening systems.
3Ease of operation
If rigid fixed mounting is used, then the stability is high, but the ease of access and modification deteriorates
Solution Approach 1:
The mounting system incorporates dynamic characteristics through the hollow section design, which allows for controlled movement and adjustment along the longitudinal axis while maintaining stability in other directions. The internal channels enable equipment to be slid in and out along the axis while the external structure remains rigid.
Solution Approach 2:
Different regions of the hollow section chassis members have different structural qualities optimized for specific functions. The external surfaces provide rigid mounting surfaces for stability, while internal channels and recesses provide access pathways and adjustment features, creating local variations in structural properties.
