Snap-Fit Waterproof Cover Structure to Eliminate Screw Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor monitor covers require screws for sealing, leading to increased assembly costs, time, and risk of lost screws, as well as additional components like hanging-preventing lines, which complicates usage and production.
Innovation Solution
A waterproof cover structure featuring a cover body with a ring-shaped rib and a detachable waterproof sealing ring, integrated hanging-preventing portion, and locking mechanism, allowing for screwless assembly and enhanced convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to seal the cover body with the main body, then the waterproof function is improved, but the assembly cost and time increase
Solution Approach 1:
The patent extracts and eliminates the screws from the sealing mechanism. Instead of using traditional screw-based sealing, the invention employs a snap-fit structure where the cover body directly engages with the main body through elastic deformation of the sealing ring, removing the need for separate fastening components and reducing assembly steps.
Solution Approach 2:
The patent replaces the mechanical screw-fastening system with an elastic deformation-based sealing system. The sealing ring utilizes its own elasticity to create the sealing effect, substituting complex mechanical fastening with a simpler elastic constraint mechanism that achieves both sealing and fixation simultaneously.
2Reliability
If screws are used to fix the cover body, then the sealing is improved, but the assembly cost increases due to screws being dropped or lost
Solution Approach 1:
The invention removes screws entirely from the assembly process, extracting the fastening function from the sealing mechanism. This eliminates the risk of screw loss and the associated costs of replacement and reassembly, while maintaining effective sealing through the elastic snap-fit structure.
Solution Approach 2:
The patent merges the sealing function and the fixation function into a single integrated mechanism. The sealing ring simultaneously provides both the waterproof seal and the mechanical fixation through its elastic deformation, eliminating the need for separate screws and reducing overall assembly cost.
3Reliability
If a hanging-preventing line is added to prevent the cover body from dropping, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The invention merges the hanging-prevention function with the sealing structure itself. The sealing ring's elastic deformation mechanism inherently provides both sealing and mechanical retention, preventing the cover from dropping without requiring an additional separate hanging-preventing line, thus reducing structural complexity.
4Reliability
If multiple screws and additional components are used, then the waterproof function is ensured, but the ease of operation deteriorates
Solution Approach 1:
The invention extracts all unnecessary fastening components (screws, hanging lines) from the design, leaving only the essential snap-fit sealing mechanism. This simplifies the user operation to a single action of pressing the cover onto the main body, significantly improving ease of operation while maintaining waterproof functionality.
Solution Approach 2:
The sealing ring performs self-service by using its own elastic properties to simultaneously achieve sealing, fixation, and hanging prevention. The structure is self-sufficient, requiring no external tools or additional components, which greatly enhances user convenience.
