Wall Distributor Housing Lock Protection Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall distributor housings lack robustness against external influences and secure separation of installation and user areas, with locks often requiring IP65 compliance and being vulnerable to dust and dirt ingress.
Innovation Solution
A wall distributor housing design with a base part featuring separate chambers for installation and user areas, where the first lock is arranged in a sub-chamber, allowing for better protection against dust and dirt without demanding IP65 compliance, and the second cover is fixed with a snap-in closure or lockable by a second lock, enhancing security and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lock is arranged in the main chamber, then the lock is easily accessible, but the chamber interior is vulnerable to dust and dirt ingress
Solution Approach 1:
The patent divides the housing into a main chamber and a separate sub-chamber, placing the lock in the sub-chamber. This segmentation isolates the lock from the main chamber environment while maintaining accessibility through a dedicated access opening, resolving the contradiction between lock accessibility and protection from dust/dirt.
Solution Approach 2:
The sub-chamber acts as an intermediary space between the lock and the main chamber. It provides a protected environment for the lock while allowing controlled access through a separate opening, preventing direct exposure to dust and dirt in the main chamber.
2Object-affected harmful factors
If the first cover completely covers the base part, then maximum protection is provided, but material usage increases
Solution Approach 1:
The first cover is divided into two functional sections: a first section that overlaps with the second cover for protection, and a second section that provides access to the sub-chamber. This segmentation reduces material usage compared to a completely enclosing cover while maintaining necessary protection.
Solution Approach 2:
Instead of complete coverage, the first cover provides partial coverage through overlapping sections. The overlap area provides sufficient protection for the lock and critical components, eliminating the need for excessive material while maintaining adequate protection.
3Object-affected harmful factors
If the second cover completely covers the first cover, then maximum protection is provided, but material usage and complexity increase
Solution Approach 1:
The second cover is segmented into a first section that overlaps the first cover for protection and a second section that provides access to the main chamber. This segmentation reduces material usage while maintaining protection where needed.
Solution Approach 2:
The second cover provides partial coverage by overlapping only the critical first cover section. This eliminates the need for complete coverage, reducing material usage while providing sufficient protection for the lock and installation connections.
4Object-affected harmful factors
If separate sub-chamber is introduced for the lock, then lock protection is improved, but device complexity increases
Solution Approach 1:
The housing is segmented into a main chamber and a sub-chamber, with the sub-chamber serving the specific function of housing the lock. This segmentation provides protection without requiring complex separate mechanisms, as the sub-chamber is integrated into the overall housing structure.
