Two-piece distribution cabinet inner body for modular repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Distribution cabinets face challenges in rapid repair and maintenance without deactivating the system, due to varied operator requirements and high storage and repair costs, as well as the risk of damage from collisions which often necessitates complete deactivation for minor issues.
Innovation Solution
The distribution cabinet is designed with a two-part body frame, where the mounting frame is attached to the lower part, allowing the upper part to be easily removed and repaired or replaced without interrupting operations, using a modular design with transverse bolts and form-fitting connections for quick assembly and disassembly, and temporary support for internal components during replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the distribution cabinet is designed as a single integrated body, then structural stability is improved, but repair time increases and system deactivation is required
Solution Approach 1:
The distribution cabinet is divided into a lower body and an upper body that can be separated from each other. The mounting frame with electrical components is attached to the lower body, while the upper body can be removed independently for repair without affecting the lower body and its components.
2Ease of manufacture
If the distribution cabinet is designed as a single integrated body, then manufacturing simplicity is improved, but storage costs increase due to need for multiple variants
Solution Approach 1:
The cabinet is segmented into modular upper and lower bodies that can be produced separately and stored independently. This modularity allows manufacturers to produce a base lower body once and create different upper body variants as needed, reducing the need to store complete assembled cabinets for each variant.
Solution Approach 2:
The lower body with the mounting frame is designed as a universal base that can accommodate different upper bodies for various network operators' requirements. This allows a single lower body to serve multiple configurations, reducing the number of variants that need to be manufactured and stored.
3Stability of the object's composition
If the mounting frame is attached to the entire body frame, then structural stability is improved, but repair complexity increases when damage occurs
Solution Approach 1:
The mounting frame is attached only to the lower body, separating it from the upper body. This segmentation ensures that damage to the upper body does not affect the mounting frame or electrical components, simplifying repair procedures by isolating the damage to a removable upper body section.
4Productivity
If the upper body is designed to be easily removable, then repair speed is improved, but structural stability decreases
Solution Approach 1:
The upper body is designed as a separate removable module that can be quickly detached from the lower body using simple fastening elements. This segmentation allows rapid removal for repair while maintaining the structural integrity of the lower body and its mounting frame.
Solution Approach 2:
The upper body is pre-designed with connection interfaces and fastening elements that enable quick attachment and detachment. This preliminary preparation of the connection system allows repair personnel to rapidly remove or replace the upper body without complex disassembly procedures.
