Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation process of connecting elements in electrical junction boxes is complex and lacks guidance, leading to difficulties in accurately positioning and securing electrical lines during connection.
Innovation Solution
An electrical junction box design featuring a housing base with a guide device and elongated holes in the fastening section, allowing the connecting element to be guided and fixed using a screw or pin, ensuring precise installation and providing a metal fastening mechanism for secure attachment to a wall, even if the housing is damaged in a fire.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connecting element is freely movable during installation, then it is easy to position, but it lacks guidance leading to inaccurate positioning
Solution Approach 1:
The guide device acts as an intermediary between the connecting element and the housing base. It provides guided movement through the elongated hole, allowing the connecting element to be easily positioned while ensuring accurate alignment with the housing base during installation.
2Reliability
If the connecting element is securely fixed, then connection reliability is improved, but installation complexity increases
Solution Approach 1:
The guide device enables the connecting element to guide itself into the correct position during installation. The elongated hole allows the connecting element to be inserted and positioned without complex alignment procedures, while the guide device ensures secure fixation once in place.
3Ease of manufacture
If the housing is made of combustible material, then manufacturing cost is reduced, but functionality is lost during fires
Solution Approach 1:
The patent employs a composite construction where the housing base is made of non-combustible material (such as metal) to ensure fire resistance, while other parts of the housing may use combustible materials. This composite approach maintains manufacturing feasibility while ensuring the critical housing base remains functional during fires.
