Controller With Removable Control Unit for Display Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing controller configurations for display devices require cumbersome removal of the board box to replace the control board, leading to poor maintainability.
Innovation Solution
A controller design with a housing that includes slots for easy insertion and removal of the control unit, a backboard connected to the control unit, and connectors for establishing connections between the backboard and the display device, allowing for simple replacement and maintenance of the control unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the control board is housed in a board box that must be removed for replacement, then the control board is protected and integrated with the display device, but the replacement process becomes troublesome and maintainability deteriorates
Solution Approach 1:
The controller is divided into separate functional modules: the control unit (control board) is made independently replaceable from the housing and backboard. The control unit can be removed and replaced without affecting other components, enabling easy maintenance while keeping the overall system integrated.
Solution Approach 2:
The control unit is extracted as a separate, independently replaceable component from the housing assembly. This allows the control board to be taken out for replacement without removing the entire housing or affecting other components, directly improving maintainability.
2Ease of repair
If the control unit is made easily replaceable through simple insertion and removal, then maintainability improves, but the connection stability between the control unit and display device may be compromised
Solution Approach 1:
The backboard is pre-equipped with connectors that automatically establish electrical connections when the control unit is inserted into the housing. This preliminary preparation of connection interfaces ensures stable connectivity is achieved automatically through the simple act of insertion, without requiring additional steps that would complicate replacement.

AI summary
A controller is attached to a back face of a display device. The controller includes: a housing; a control unit removably accommodated in a slot formed in the housing and configured to control the display device; a backboard provided inside the housing on the interior side with respect to the direction of insertion of the control unit and connected to the control unit; and a second connector connected to a first connector provided for the display device to establish connection between the backboard and the display device.
