Tool-Free Display Module Mounting for Intelligent Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intelligent electronic devices, such as power meters, require the use of tools to attach or detach the display module, which is inconvenient and may lead to increased complexity and potential errors.
Innovation Solution
The intelligent electronic device features a housing with a protuberance structure that includes elongate protrusions and hexagonal protrusions, allowing for easy attachment and detachment of the display module without the need for tools, and enabling optional connection to a DIN rail or display module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to secure the display module to the power meter, then the connection is strong and reliable, but tools are required and the operation becomes complex
Solution Approach 1:
The connection mechanism is segmented into a mounting clip with engagement portions and corresponding engagement features on the housing and display module. The mounting clip acts as a separate component that provides both secure connection and easy operation through its specific geometry, resolving the contradiction between reliable connection and ease of operation.
Solution Approach 2:
The mounting clip serves as an intermediary element between the housing and the display module. It mediates the connection by providing engagement portions that interact with engagement features, enabling both strong connection and tool-free operation without requiring direct screw-fastening between components.
2Reliability
If multiple parts are used to attach the display module, then the connection is secure, but the number of parts increases and complexity increases
Solution Approach 1:
The mounting clip combines multiple functions into a single component: it provides structural support, creates secure engagement through its engagement portions, and enables easy installation/removal through its geometry. This merging of functions reduces the total number of parts while maintaining connection security.
Solution Approach 2:
The mounting clip is designed as a multi-functional component that serves as both a structural element and a fastening mechanism. It simultaneously provides mechanical support and secure attachment through its engagement portions, eliminating the need for separate screws, washers, and other fastening components.
3Reliability
If tools are required to attach or detach the display module, then the connection is secure, but user convenience decreases and potential errors increase
Solution Approach 1:
The mounting clip is designed to be self-servicing through its specific geometry. The engagement portions and corresponding features create a self-locking mechanism that secures the display module without requiring tools. The user can simply snap the components together and apart, making the system self-serviceable while maintaining secure connection.

AI summary
An intelligent electronic device that can be optionally connected to a DIN rail or a display module without requiring the use of tools. An intelligent electronic device for measuring a characteristic of electricity is provided, which is enclosed in a housing that has a front and a rear. The housing defines an interior volume and includes a sensor configured to sense a characteristic of electricity. The rear of the housing includes a first protuberance structure disposed on a first outer surface. The first protuberance structure contains elongate protrusions and at least one hexagonal protrusion on a second outer surface. The elongate protrusions include upper protrusions and lower protrusions. The lower protrusions include left protrusions and right protrusions, and the at least one hexagonal protrusion is disposed between the left protrusions and right protrusions.
