Threaded Sealed Enclosure for Compact Waterproof Communication Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication equipment cases face challenges with multiple screws requiring assembly and disassembly, space for screws, and the need for washers or sealants to achieve waterproofing, making maintenance inconvenient and increasing size.
Innovation Solution
A case design with internal and external screw threads on an upper and bottom cover, respectively, forming a sealed accommodating space without the need for screws, washers, or sealants, using a washer for additional sealing and anti-loose glue for enhanced security and assembly ease.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple screws are used to lock the covers during assembly, then the waterproof effect is ensured, but the device complexity and assembly/disassembly inconvenience increase
Solution Approach 1:
The patent merges the fastening function and sealing function into a single integrated screw thread structure. The screw thread is formed directly on the cover edges, eliminating the need for separate screws and washers. This integration reduces the number of components while maintaining both the waterproof effect and simplifying assembly/disassembly operations.
Solution Approach 2:
The patent extracts the sealing function from separate sealing components (washers, sealants) and integrates it directly into the screw thread structure itself. The screw thread design includes sealing features built-in, such as the thread profile and engagement mechanism that create a sealed connection between covers without requiring additional sealing elements.
2Reliability
If multiple screws and sealing components are used, then the waterproof effect is achieved, but the device size increases due to space requirements for these components
Solution Approach 1:
The patent combines multiple functions (fastening, sealing, waterproofing) into a single screw thread structure, eliminating the need for separate screws, washers, and sealants. This integration significantly reduces the space required for these components, thereby minimizing the overall device size while maintaining effective waterproofing.
3Reliability
If washers or sealants are used with screws to ensure waterproofing, then the sealing effect is improved, but the ease of manufacture and assembly is reduced
Solution Approach 1:
The patent integrates the sealing function directly into the screw thread structure, eliminating the need for separate washers or sealants. The screw thread is designed with built-in sealing features that create a waterproof seal through the thread engagement itself, simplifying both manufacturing and assembly processes while maintaining effective sealing.

AI summary
A case with screw thread in a sealed manner for communication equipment includes an upper cover and a bottom cover. The inner surface of the upper cover has an internal screw thread. The outer surface of the bottom cover has an external screw thread. When the external screw thread is fixed with the internal screw thread, the inner surface of the upper cover is in contact with the outer surface of the bottom cover in a sealed state, and the upper cover and the bottom cover form a receiving space. The case provides the following advantages: quickly and repeated assembly and disassembly; no need for any space for bolts so as to minimizes the size; without bolt, no need for washers or sealant; good sealing properties and good waterproof effect so as to prevent water from entering the case.
