Watch Cover Display Screen Sealing Ring Waterproofing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing watches face challenges in achieving effective waterproofing between the watch case and the display screen, leading to moisture ingress and potential damage to the circuit module.
Innovation Solution
A waterproof structure for a watch is implemented, featuring a first sealing ring between the watch cover and the display screen, which enhances the airtightness and overall waterproof performance by preventing moisture entry through the connection position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If adhesive bonding is used to fix the display screen, then the display screen can be secured to the watch case, but the waterproof performance between the watch cover and display screen deteriorates
Solution Approach 1:
A first sealing ring is introduced as an intermediary component between the watch cover and the display screen. The sealing ring has a first sealing surface that contacts the watch cover and a second sealing surface that contacts the display screen, creating a dedicated waterproof barrier that separates the bonding function from the sealing function. This resolves the contradiction by providing both mechanical attachment and waterproofing through a specialized intermediary component rather than relying on adhesive alone.
2Device complexity
If structural fit alone is used for waterproofing, then the structure remains simple, but moisture easily enters the interior of the watch from connection positions
Solution Approach 1:
The first sealing ring is made from elastic sealing material, providing a flexible waterproof barrier that can deform to accommodate manufacturing tolerances and assembly variations. This flexible sealing approach maintains relative structural simplicity while significantly improving waterproof performance compared to rigid structural fit alone, as the elastic material can conform to the mating surfaces and maintain reliable sealing.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution significantly improves the waterproof performance of the watch by creating a robust seal between the watch cover and the display screen, while also providing shock absorption and buffering when the watch falls, thereby protecting the internal components.
Implementation Method 1
a first sealing ring is provided between the watch cover and the display screen; the first sealing ring is fixedly provided on the watch cover and abuts against the display screen
Implementation Method 2
a connection structure between the watch cover and the display screen is transitioned through the first sealing ring, which renders a soft elasticity of the first sealing ring play serve as a buffer and shock absorbing role when the watch falls

AI summary
A waterproof structure for watch is provided, which includes a watch case, a watch cover, a bottom case, and a circuit module. The watch cover is fixedly provided on one side of the watch case, the bottom case is fixedly provided on the other side of the watch case, and the circuit module is provided within the watch case. A display screen is provided between the watch case and the watch cover, and a first sealing ring is provided between the watch cover and the display screen. The first sealing ring is fixedly provided on the watch cover and abuts against the display screen, rendering it difficult for moisture to enter an interior of the watch and damage the circuit module through a connection position between the watch cover and the display screen, thereby improving a connection sealing between the water cover and the display screen.
