Shock absorption bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Equipment cabinets used for rack-mounted electronics face challenges in maintaining stability and reducing relative movement when subjected to shock and vibration, particularly in moving environments, leading to stress on equipment and fasteners.
Innovation Solution
A shock absorption bracket is designed with an absorption leg and damping pads attached to a support leg, configured to absorb and dampen shock and vibration energy by positioning damping pads to face support surfaces within the equipment cabinet, thereby reducing relative movement between the equipment and the cabinet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If damping pads are added to the bracket, then shock absorption capability is improved, but device complexity increases
Solution Approach 1:
The bracket is divided into distinct functional segments: the absorption leg with damping pads for shock absorption, and the support leg for structural support. This segmentation allows each part to perform its specific function efficiently while maintaining overall system simplicity.
Solution Approach 2:
The damping pads act as an intermediary element between the rack equipment and the bracket structure. They mediate the shock transmission by absorbing energy through deformation, protecting both the equipment and the bracket while adding minimal complexity to the overall system.
2Stability of the object's composition
If the bracket structure is made more robust to reduce relative movement, then stability is improved, but weight increases
Solution Approach 1:
The bracket utilizes the damping pads' material properties and deformation characteristics as a variable parameter to achieve stability. Instead of increasing structural mass, the system changes the mechanical parameters of the damping pads (viscoelastic properties, thickness, hardness) to optimize shock absorption while maintaining lightweight construction.

Function Achieved in This Case
The solution effectively reduces stress on equipment and fasteners by absorbing kinetic energy and damping vibrations, maintaining stability and minimizing damage from mechanical shocks and vibrations.
Implementation Method 1
The damping pads may be configured to absorb and/or dampen shock impulses and/or vibrations transmitted from racked equipment within or around the equipment cabinet to the shock absorption bracket
Implementation Method 2
configured to absorb and dampen shock impulses and/or vibrations transmitted to one or more damping pads

AI summary
In some examples, a shock absorption bracket includes one or more damping pads coupled to a facing surface of an absorption leg. The absorption leg is attached to a support leg and defines an internal corner with the support leg. The support leg is configured to attach to an equipment cabinet. The shock absorption bracket may be configured to define a gap between the damping pads and one or more support surfaces of the equipment cabinet. The shock absorption bracket may be configured to attach to a rear section of an equipment cabinet having an equipment access in a front section of the equipment cabinet.
