Solution Overview

Problem

Existing water containers suffer from water wastage due to gravity-fed valves and require both hands for operation, limiting access and efficiency.

Innovation Solution

An adapter system that connects an electric pump directly to water containers, allowing controlled water flow without leakage and enabling one-handed operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If gravity-fed valves are used in water containers, then water flow is enabled, but water wastage occurs due to constant flow before user can control it

Engineering Contradiction:

Improvewater accessVSAvoidwater wastage

Core Design Contradiction:

Ease of operationVSLoss of substance

Solution Approach 1:

The electric pump activates before the user needs water, priming the system and positioning water for immediate delivery. This eliminates the delay and wastage associated with gravity-fed valves where water flows continuously before the user can position themselves to receive it.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces the mechanical gravity-fed valve system with an electrically controlled pump system. This substitution allows for precise electronic control of water flow, eliminating the inherent wastage of gravity-based continuous flow systems.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If push button valves are used, then one handed operation is enabled, but water wastage still occurs due to constant flow

Engineering Contradiction:

Improveone handed operationVSAvoidwater wastage

Core Design Contradiction:

Ease of operationVSLoss of substance

Solution Approach 1:

The patent replaces the push button valve system with an electrically controlled pump. While both allow one-handed operation, the electric pump provides superior control over water flow, delivering water only when needed and in precise amounts, thereby eliminating the constant flow wastage inherent in valve-based systems.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The electric pump system can incorporate sensors that detect when water has reached the user or when the container is empty, providing feedback to stop the pumping action. This feedback mechanism prevents both over-pumping and wastage, something that cannot be achieved with simple push button valves.

Inventive Principle:

Principle #23Feedback
