Solution Overview

Problem

Current DIN-mounted devices require tools and two hands for installation and removal, are difficult for larger devices, and lack sturdy flat-surface mounting options.

Innovation Solution

A mounting enclosure assembly with a locking mechanism that includes a release handle and hinged armature, allowing single-handed operation and tool-free installation/removal, and enabling secure mounting to both DIN rails and flat surfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional DIN clips are used for mounting, then the device can be secured to the DIN rail, but tool and two hands are required for installation and removal

Engineering Contradiction:
Improveease of installation and removalVSAvoidcomplexity of mounting mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The mounting bracket is designed to self-latch onto the DIN rail through spring-loaded arms that automatically engage with the rail's flanges when the bracket is inserted, eliminating the need for tools or manual manipulation of separate clips

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The mounting bracket integrates multiple functions into a single component: it combines the mounting clip functionality with the structural support bracket, allowing the entire assembly to be mounted to the DIN rail as one unit rather than requiring separate clips for each function

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If multiple DIN clips are used for larger devices, then the device can be securely mounted, but removal becomes difficult and time consuming

Engineering Contradiction:
Improvesecurity of mountingVSAvoidtime for installation and removal
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The spring-loaded mounting arms automatically engage and disengage from the DIN rail flanges through a single pushing motion on the release mechanism, eliminating the need for multiple manual operations to release each clip individually

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The mounting arms are designed with spring mechanisms that provide dynamic engagement - they automatically snap into the locked position during installation and can be quickly released by overcoming the spring force, enabling rapid mounting and dismounting

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If traditional mounting options are used for flat surfaces, then mounting is possible, but the mounting is not sturdy or requires difficult installation

Engineering Contradiction:
Improvemounting surface flexibilityVSAvoidsturdiness of mounting
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The mounting bracket is designed with dual functionality - it can be mounted to DIN rails using the spring-loaded arms, or alternatively mounted to flat surfaces using the protruding mounting plate with holes, allowing the same device to be installed in different environments without requiring different mounting hardware

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A mounting enclosure assembly is configured to mount an electronic component onto a Deutsches Institut für Normung (DIN) rail. The mounting enclosure includes a mounting bracket including a body having a slot configured to receive the DIN rail therein. A locking mechanism is operatively connected to the body of the mounting bracket to selectively engage and disengage the mounting enclosure assembly to the DIN rail. There is also a position for mounting the mounting bracket to a flat surface, e.g. where there is no DIN rail.
