Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses face challenges in accessing and detachably mounting circuit cases from cabinets, particularly when multiple display modules are tiled in various directions, necessitating improved structural design for easy maintenance and installation.
Innovation Solution
The display apparatus features a detachable circuit case that can be accessed from both the front and rear, utilizing magnetic attraction and fastening mechanisms for secure mounting and detachment, allowing for easy installation and maintenance of display modules and circuit cases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the circuit case is fixed to the cabinet for stable operation, then reliability is improved, but ease of repair deteriorates
Solution Approach 1:
The circuit case is divided into separate detachable modules that can be independently accessed from the front of the cabinet. Each circuit case is segmented into removable units connected via connection brackets, allowing maintenance personnel to access and repair circuit components without dismantling the entire cabinet structure.
Solution Approach 2:
Connection brackets serve as intermediary components between the cabinet and circuit cases. These brackets provide a detachable coupling mechanism that maintains stable operation when connected but allows easy separation for repair. The brackets act as mediators that enable both reliable connection and convenient disconnection.
2Ease of repair
If the circuit case is made detachable for easy maintenance, then ease of repair is improved, but device complexity increases
Solution Approach 1:
The connection brackets are designed with universal functionality to serve multiple purposes: providing structural support, enabling detachable connection, and facilitating alignment during assembly. This multi-functionality reduces the need for separate specialized components, thereby limiting the increase in device complexity.
Solution Approach 2:
The circuit cases are nested within the cabinet structure through the connection brackets, which are themselves nested between the cabinet frame and the circuit case assemblies. This nesting arrangement allows the detachable components to be integrated into the existing cabinet architecture without requiring entirely separate mounting systems.
3Ease of operation
If multiple access points are provided for circuit case detachment, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The connection brackets are asymmetrically designed with different engagement features at the front and rear of the cabinet. The front access utilizes quick-release latches that can be operated from the front side, while the rear access employs corresponding engagement slots. This asymmetric design enables multi-directional access without requiring identical complex mechanisms at both ends.
