Solution Overview
Problem
Conventional wrist watches are vulnerable to water exposure, which can short circuit the electronic components, and existing liquid-powered devices lack effective protection against environmental moisture and their own water-based power sources.
Innovation Solution
A liquid-powered wrist watch design featuring a housing assembly with a liquid tank and power assembly that are separately sealed, utilizing an electrolyte solution to generate electricity and a mechanical clock mechanism without an external power source, with a pressure relief assembly to manage gas buildup and prevent water leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the electronic components are exposed to the water-based power source, then the device can be simpler in structure, but the electronic components will be short-circuited by water exposure
Solution Approach 1:
The device is divided into separate compartments: a liquid reservoir containing the electrolyte solution and a separate electronic component housing. This segmentation allows the electronic components to be isolated from direct contact with water while still enabling power transmission through the electrolyte medium, thus resolving the contradiction between structural simplicity and component protection.
Solution Approach 2:
The electrolyte solution acts as an intermediary medium that enables electrical power transmission from the liquid reservoir to the electronic components without requiring direct exposure. The solution conducts electricity while the sealed compartments prevent harmful water contact, allowing power transfer without the short-circuit risk that would otherwise necessitate complex protection mechanisms.
2Adaptability or versatility
If the device uses a water-based power source, then it can operate without external power, but it becomes vulnerable to environmental moisture and gas buildup
Solution Approach 1:
The device incorporates preventive measures against harmful effects before they occur: sealed compartments are designed to prevent environmental moisture ingress, and pressure relief mechanisms are pre-configured to release gas buildup before it causes damage. This preliminary protection allows the device to maintain water-based power independence while mitigating vulnerability to moisture and pressure.
Solution Approach 2:
The device utilizes sealed membranes and flexible sealing structures that isolate the electrolyte reservoir from the external environment. These seals prevent environmental moisture from contaminating the power source while allowing the system to maintain its water-based power functionality, thus enabling external power independence without exposure to harmful environmental factors.
3Device complexity
If the liquid tank and power assembly are integrated, then the device structure is simpler, but water can leak and short circuit the electronics
Solution Approach 1:
The liquid tank assembly and power assembly are segmented into separate sealed units. The liquid tank contains the electrolyte solution while the power assembly houses the electronic components in a separate sealed compartment. This segmentation maintains relative structural simplicity while effectively preventing water leakage and short circuits through physical isolation of the liquid and electronic systems.
