Shock-Proof Cabinet Support Structure for Anti-Leaning Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical cabinets are prone to deformation and instability due to stress concentration at the connection between adjustable feet and the cabinet, leading to potential leaning or falling during heavy jarring events.
Innovation Solution
The implementation of shock-proof units, comprising a shock-proof member and a carrier with mounting grooves and locking holes, are integrated into the cabinet design to enhance shock resistance and prevent inclination by distributing the weight and providing additional support through connecting members and supporting members.

Engineering Contradiction Analysis
1Stability of the object's composition
If adjustable feet are installed at the bottom of the cabinet to prevent wheels from moving, then the cabinet stability is improved, but stress concentration occurs at the connection portion between the adjustable feet and the cabinet during heavy jarring, causing deformation or damage
Solution Approach 1:
The supporting structure is divided into multiple components: adjustable feet for height adjustment, shock-proof plates distributed at multiple locations to absorb impact, and reinforcing plates to strengthen the connection portions. This segmentation allows each component to perform its specific function, distributing the stress and preventing concentration at single points.
Solution Approach 2:
Shock-proof plates are installed at the bottom of the cabinet and at connection portions before heavy jarring occurs. These plates act as pre-positioned cushioning elements that absorb and distribute impact forces during sudden shocks, preventing stress concentration and deformation at critical connection points.
2Ease of manufacture
If the cabinet is designed with simple bottom support structure, then the manufacturing complexity is reduced, but the cabinet becomes vulnerable to leaning or falling over during heavy jarring events
Solution Approach 1:
The shock-proof cabinet merges multiple protective functions into a unified structure: the shock-proof plates are integrated with the cabinet bottom and connection portions, combining support, shock absorption, and reinforcement functions. This integrated approach enhances reliability without requiring complex separate systems, maintaining ease of manufacture while improving shock resistance.
Solution Approach 2:
Reinforcing plates are strategically placed at specific locations where stress concentration is most likely to occur during heavy jarring. This local reinforcement approach provides enhanced protection at critical points without requiring complete structural redesign, maintaining manufacturing simplicity while improving overall cabinet reliability under shock conditions.

AI summary
A cabinet for electronic components, which is resistant to shocks resulting in deformation of a housing and unsteady leaning of a cabinet casing, includes a cabinet body, a plurality of supporting units, and a plurality of shock-proof units. The plurality of supporting units is disposed on a bottom portion of the cabinet body, and each of the plurality of shock-proof units includes a shock-proof member and a carrier. An end of the shock-proof member rests on the floor or ground, and the other end is connected to the cabinet body. The carrier is connected to the cabinet body and supports the cabinet body, inclination of the cabinet body following heavy jarring and impacts is prevented.
