Electrical Enclosure Lid Hinge via Through-Hole Connector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical mounting enclosures face issues where the lid can be lost during installation or obstructs the work area due to its rigid hinge structure, which is often made of plastic and tends to move back towards the opening, disrupting installation processes.
Innovation Solution
An electrical mounting enclosure design featuring a primary and secondary through hole system that allows for connection via an elongate connecting portion, enabling the lid to be easily attached and adjusted in angle, allowing for greater flexibility and avoiding obstruction during installation, with the option to use a cable tie or a built-in connecting portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lid is connected to the housing through a rigid hinge, then the lid remains safe without being lost, but the lid obstructs the work area and disrupts installation by moving back towards the opening
Solution Approach 1:
The connection between lid and housing is segmented into two separate through-holes (first and second) positioned at different locations, allowing the lid to be secured while enabling independent movement and positioning away from the housing during installation
Solution Approach 2:
An elongate connecting portion acts as an intermediary element that passes through both through-holes to connect the lid and housing, providing flexibility in positioning the lid away from the housing while maintaining secure attachment
2Ease of operation
If the lid is placed separately during installation, then it does not obstruct the work area, but the lid can be lost
Solution Approach 1:
The through-holes are pre-formed in the housing and lid, and the elongate connecting portion can be preliminarily inserted to temporarily secure the lid at a distance from the housing during installation, allowing easy access while preventing loss
Solution Approach 2:
The elongate connecting portion serves as a mediator that can be inserted through the through-holes to securely attach the lid to the housing while allowing the lid to be positioned away from the housing opening during installation work
3Ease of operation
If the lid is connected through multiple through-holes with an elongate connecting portion, then the lid can be securely attached and positioned away from the housing, but the device complexity increases
Solution Approach 1:
The elongate connecting portion serves multiple functions: it secures the lid to the housing, allows the lid to be positioned away from the housing during installation, and can be made from standard materials like cable ties, reducing the need for specialized components
Solution Approach 2:
The elongate connecting portion can be made from inexpensive materials such as cable ties, which are readily available and easy to replace, reducing the complexity and cost of the connection structure while achieving the desired functionality

AI summary
The invention relates to an electrical mounting enclosure (1) for surface-mounted electrical installation comprising a housing (2) and a lid (3) connectable to the housing (2) and arranged to close the opening (23) of the housing (2) for providing a closed electrical mounting enclosure (1) having an interior space (10). The electrical mounting enclosure (1) comprises a primary through hole (4) arranged to the housing (2), a secondary through hole (5) arranged to the lid (3), the primary through hole (4) of the housing (2) and the secondary through hole (5) of the lid (3) are adapted to receive a same elongate connecting portion (6) so that the elongate connecting portion (6) passes through the primary through hole (4) and the secondary through hole (5) to connect the housing (2) and the lid (3) to each other through the connecting portion (6).
