Water dispenser
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water dispensers with cooling and heating functionalities violate Jewish Halacha restrictions during holy-days, particularly in the use of electrical appliances for on-demand cooling or heating, and lack integrated water filtration capabilities.
Innovation Solution
A water dispenser designed with both week-day and holy-day operation modes, utilizing electromechanical valves that switch to mechanical operation during holy-days to maintain Halacha compliance, featuring a mechanical delay mechanism to prevent water pressure buildup and a separate hot water reservoir pre-filled before holy-days, along with integrated water treatment and filtration systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electrical valves and heating/cooling functions are used during holy-days, then on-demand water dispensing is improved, but Jewish Halacha requirements are violated
Solution Approach 1:
The system dynamically switches between electrical and mechanical valve operation modes based on whether it is a holy-day or regular day. During holy-days, the electromechanical valves are configured to operate mechanically rather than electrically, while still enabling on-demand dispensing through mechanical actuation of the valves.
Solution Approach 2:
The water dispensing system is segmented into separate hot and cold water reservoirs with independent valve control. This allows selective operation of different components during holy-days - the cold water system can operate with mechanical valves while the hot water system prevents heating entirely, maintaining Halacha compliance while preserving functionality.
2Ease of operation
If a separate hot water heating device is used during holy-days, then hot water provision is improved, but kitchen counter space is increased
Solution Approach 1:
The patent merges the hot water storage and dispensing functionality into the existing water dispenser unit. The hot water reservoir is integrated within the dispenser housing, and the hot water dispensing nozzle is incorporated into the front panel, eliminating the need for a separate standing heating device on the kitchen counter.
Solution Approach 2:
The water dispenser is designed to perform multiple functions - it can dispense both cold and hot water, and it can operate in both electrical mode (regular days) and mechanical mode (holy-days). This multi-functionality eliminates the need for separate dedicated devices for different purposes.
3Ease of operation
If a separate hot water heating device is used during holy-days, then hot water provision is improved, but water filtration functionality is lost
Solution Approach 1:
The water treatment unit is merged into the main water line that supplies both the cold and hot water reservoirs. The filtration system processes water before it is distributed to different reservoirs, ensuring that both cold and hot dispensing outlets provide filtered water.
Solution Approach 2:
The integrated water treatment unit provides universal filtration service to all water dispensing functions - both cold and hot water outlets benefit from the same filtration system, maintaining versatility across all dispensing modes and functions.
4Productivity
If water pressure in the main feed line increases during holy-day mode, then cold water dispensing is improved, but water flows into the hot water reservoir causing boiling
Solution Approach 1:
A check valve is introduced as an intermediary component between the main water feed line and the hot water reservoir. This check valve allows water to flow into the cold water reservoir during holy-day mode while preventing reverse flow into the hot water reservoir, thereby eliminating the risk of water boiling while maintaining cold water dispensing functionality.
Solution Approach 2:
The system replaces electrical control mechanisms with mechanical valve operation during holy-days. The electromechanical valves are actuated mechanically rather than electrically, and the check valve uses mechanical pressure differential to control water flow direction, ensuring Halacha compliance while maintaining system functionality.
