Diving Watch Assembly with Integrated Pressure Gauges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional diving watches have a larger volume and heavier weight due to separate water pressure and air pressure gauges, making them less portable and prone to misjudgment as divers need to switch between different display surfaces for information.
Innovation Solution
A diving watch assembly with an airtight and waterproof housing containing both air pressure and water pressure watch cores, with scales displayed on a single dial disc, reducing the overall volume and weight while enhancing readability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate water pressure gauge and air pressure gauge are used, then each gauge can be optimized for its specific function, but the overall volume and weight of the diving watch assembly increases
Solution Approach 1:
The patent combines the water pressure gauge and air pressure gauge into a single integrated housing, with both gauges sharing a common dial disc and housing structure. This merging reduces the overall volume and weight of the diving watch assembly while maintaining the functional independence and measurement precision of both pressure sensing systems.
Solution Approach 2:
The single housing structure serves multiple functions by accommodating both the water pressure gauge and air pressure gauge, along with their respective sensing mechanisms and display systems. This multi-functional design eliminates the need for separate housings, thereby reducing overall volume while preserving specialized measurement capabilities.

3Measurement precision
If separate display surfaces for water pressure and air pressure are used, then each display can be optimized for its data, but the diver needs to switch between different positions increasing misjudgment risk
Solution Approach 1:
The patent merges the display surfaces of both gauges onto a single dial disc, allowing the diver to view water pressure and air pressure information simultaneously from one position. This eliminates the need to switch between different display surfaces, reducing misjudgment risk while maintaining clear and accurate data presentation for both parameters.
Solution Approach 2:
The patent arranges the two pressure scales on different dimensional zones of the same dial disc - the water pressure scale occupies the outer annular region while the air pressure scale occupies the inner circular region. This spatial differentiation on a two-dimensional surface allows both datasets to be clearly distinguished and read simultaneously without positional switching.
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 simplifies the watch components, reduces volume and weight, and allows easy reading of diving information from a single surface, improving portability and reducing the risk of misjudgment.
Implementation Method 1
A water pressure film is provided between the lower cover and the lower opening of the housing. The water pressure film and the water pressure holes allow the water pressure watch core to sense the water pressure.
Implementation Method 2
The air pressure gauge is connected to a gas cylinder via an air pressure tube, and senses the air pressure of the gas cylinder to display air residual in the gas cylinder.

AI summary
A diving watch assembly includes an internal airtight and waterproof space formed by a housing, an upper cover, a transparent plate and a lower cover, and an air pressure watch core, a water pressure watch core and a dial disc installed in the internal airtight and waterproof space. The air pressure watch core is adapted to drive a first pointer, and the water pressure watch core is adapted to drive the second pointer. The air pressure (air amount) scale and the water pressure (water amount) scale are respectively indicated by the first pointer and the second pointer on the same dial disc.
