Hinged Housing Assembly with Adjustable Stop for Electrical Boxes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing articulated assemblies for electrical equipment boxes cannot limit the opening angle of a shutter to less than 90 degrees, which fails to meet standards in some countries requiring a maximum opening angle of 90 degrees, leading to increased product references and manufacturing costs.
Innovation Solution
An articulated assembly with an intermediate element featuring a rounded surface for pivoting and a stop mechanism to limit the opening angle, allowing the shutter to open beyond 90 degrees while easily restricting it to 90 degrees when necessary, using a rib and abutment surface configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional articulated assembly with a shutter pivotally mounted on an intermediate element is used, then the shutter can open to 180 degrees, but it cannot limit the opening angle to 90 degrees or less
Solution Approach 1:
The intermediate element incorporates both a rounded surface for free pivoting motion and a stop means that can be positioned to dynamically limit the opening angle. This dynamic design allows the same assembly to provide both unrestricted 180-degree opening and limited 90-degree opening by simply adjusting the stop position, rather than requiring different articulation systems for different standards.
Solution Approach 2:
The intermediate element is designed with multi-functionality, serving both as a pivot support (via the rounded surface) and as an angle limiter (via the stop means). This universal design allows a single product reference to comply with different country standards by adjusting the stop position, eliminating the need for multiple product variants.
2Adaptability or versatility
If different articulation systems are provided to meet standards requiring maximum 90 degree opening, then compliance with standards is achieved, but product references and manufacturing costs increase
Solution Approach 1:
The intermediate element integrates both the rounded surface for pivoting and the stop means for angle limitation into a single component. This universal design allows one product reference to serve multiple standards by simply repositioning the stop, rather than manufacturing different articulation systems for different markets.
Solution Approach 2:
The opening angle parameter can be changed by adjusting the position of the stop means on the intermediate element. This parameter adjustment allows the same physical assembly to comply with different standards (180 degrees or 90 degrees maximum) without changing the fundamental design or creating new product references.
3Adaptability or versatility
If different articulation systems are provided to meet standards requiring maximum 90 degree opening, then compliance with standards is achieved, but manufacturing costs increase
Solution Approach 1:
The intermediate element serves multiple functions (pivoting support and angle limitation) in a single component design. This reduces manufacturing complexity and costs by eliminating the need to produce different articulation systems for different markets, while still allowing compliance with various standards through simple stop position adjustment.
Solution Approach 2:
The rounded surface and stop means are merged into a single intermediate element rather than being separate components requiring different assemblies. This merging simplifies manufacturing by reducing part count and assembly steps, while maintaining the capability to meet different standards through stop position variation.

AI summary
The invention relates to an articulated assembly of a housing (100) for electrical equipment, comprising a frame (120) which delimits a central recess and a cover (140) which, pivotally mounted on the frame by means of a joint, is adapted to close this central recess, said joint comprising an intermediate element (150) pivotally mounted on the frame about a first axis (155) and cooperating with said cover (140) about a second axis (156) parallel to said first axis.According to the invention, the intermediate element has, near the second axis, on the one hand, a rounded surface (151B) intended to cooperate with said cover to allow the pivoting of said cover around the second axis, and, on the other hand, a stop means (151A) intended to cooperate with said cover to prevent the pivoting of said cover around the second axis, and said intermediate element is adapted to be attached to the frame in two different configurations oriented at 180 degrees to each other, namely, a first configuration in which the cover cooperates with said rounded surface and a second configuration in which the cover cooperates with said stop means.
