Separable Control Unit Panel Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional indicator controllers require high-precision rectangular openings on panels for attachment, which is difficult to process and limits the size of the opening, compromising water proofing and dust proofing functions, especially during close contact mounting.
Innovation Solution
A control device with a separable display and operating unit and main unit, allowing the connecting part to pass through a panel opening, with packing gripped and pressed by the unit and panel, enabling a simpler, smaller opening that does not match the main unit's shape, ensuring water proofing and dust proofing even in close contact mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the opening shape is matched to the main unit shape to ensure water proofing and dust proofing, then sealing reliability is improved, but manufacturing precision requirements increase and device complexity increases
Solution Approach 1:
The control device is divided into two separate parts: the display and operating unit that attaches to the panel, and the main unit that connects separately. This segmentation allows the opening to be sized and shaped for the display unit only, rather than matching the entire main unit dimensions, reducing manufacturing precision requirements while maintaining sealing effectiveness.
Solution Approach 2:
A connecting part (connector cable or connector) is introduced as an intermediary between the display and operating unit and the main unit. This intermediary allows the opening to be sized for the display unit while the main unit connects through this intermediate element, eliminating the need for the opening to match the main unit's shape and reducing precision requirements.
2Ease of manufacture
If the opening size is reduced to simplify processing, then ease of manufacture is improved, but the main unit cannot be properly mounted
Solution Approach 1:
The mounting process is segmented into two independent steps: first attaching the display and operating unit to the panel through a small opening, and then separately mounting the main unit. This segmentation allows the opening to be small and simple to form, while the main unit mounting is handled separately without requiring the opening to accommodate it.
Solution Approach 2:
The connecting part serves as an intermediary that passes through the small opening, enabling the main unit to be mounted separately. The connector cable or connector allows the main unit to connect to the display and operating unit without requiring the opening to be large enough for the main unit itself, thus simplifying opening formation while maintaining ease of main unit mounting.
3Device complexity
If the display and operating unit and main unit are integrated, then device complexity is reduced, but the opening must match the main unit shape increasing manufacturing difficulty
Solution Approach 1:
The control device is segmented into the display and operating unit and the main unit as separate components. This segmentation allows the opening to be designed and formed based on the smaller display unit dimensions rather than the larger main unit dimensions, significantly reducing opening shape precision requirements while the separate components are connected via the connecting part.

Function Achieved in This Case
Eliminates the need for high-precision opening formation and allows for smaller openings, guaranteeing water proofing and dust proofing functions without limiting the opening shape to the main unit's dimensions, facilitating easier attachment and reduced manufacturing complexity.
Implementation Method 1
packing positioned so as to enclose the periphery of the opening with the panel

AI summary
A display and operating unit and a main unit are connected with the ability to be separated. In a state with the connection with the main unit separated, the display and operating unit is attached to the front surface side of a panel. In this case, the connector cable is passed through an opening formed on the panel and positioned at the back surface side of the panel, and packing is positioned so as to enclose the periphery of the opening, and the display and operating unit is attached to the front surface side of the panel. Then, the main unit is fixed to the back surface side of the panel, a connector CN1 of the tip end of the connector cable is engaged with a connector of the main unit, and the display and operating unit and the main unit are connected.
