Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protection boxes for electric connections are not adequately safe, easy to manufacture, or cost-effective in preventing water sprays or liquids from reaching electric connectors.
Innovation Solution
A protection box design featuring two half-shells with internal compartments and a hinge mechanism, combined with U-shaped extensions and cable clamps, provides a secure and adaptable enclosure for electric connections, ensuring effective sealing against liquids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a protection box is designed with simple structure, then manufacturing cost is reduced, but protection reliability against water sprays deteriorates
Solution Approach 1:
The protection box is divided into two separate half-shells that can be assembled together, allowing each half to be manufactured independently using simple injection molding processes. This segmentation maintains low manufacturing costs while enabling the creation of a complete sealed enclosure when the halves are joined with overlapping edges and gaskets.
Solution Approach 2:
A flexible gasket or sealing film is introduced between the two half-shells to ensure water-tight sealing. This thin film element provides reliable protection against water sprays without requiring complex structural features, maintaining simplicity while achieving high protection reliability.
2Object-affected harmful factors
If a protection box uses complex sealing mechanisms, then protection against liquids is improved, but device complexity increases
Solution Approach 1:
The patent employs a flexible gasket or sealing film positioned between the overlapping edges of the two half-shells. This simple yet effective sealing mechanism provides robust protection against liquid penetration without introducing complex mechanical systems, maintaining device simplicity while achieving high liquid resistance.
Solution Approach 2:
Instead of using complex active sealing mechanisms that move or adjust, the patent uses a passive sealing approach where the gasket is compressed between the overlapping edges of the half-shells. This inverted approach simplifies the device by eliminating complex sealing mechanisms while maintaining effective liquid protection.
3Adaptability or versatility
If cable clamps are made adjustable, then adaptability to different cables is improved, but ease of manufacture deteriorates
Solution Approach 1:
The cable clamps are designed with an adjustable mechanism that allows them to be positioned at different locations along the half-shell and to accommodate cables of various diameters. This dynamic adjustability provides versatility for different cable types while maintaining relatively simple manufacturing through basic mechanical adjustment features rather than multiple specialized clamp designs.

AI summary
Protection box for electric connections comprising a first and a second half shell (1,2) which can be hooked to each other and overlapped onto each other so as to form a box shaped body with a seat for an electric block terminal or terminal junction box (M). The said seat is provided by the overlapping of two compartments (12, 22) each of which is centrally provided by a corresponding half shell (1,2) and the sides which delimit one of said compartments surmount and cover the sides which delimit the other compartment.
