Solution Overview

Problem

A significant amount of water is wasted daily in households and businesses during activities such as waiting for warm water, rinsing, and brushing teeth, which not only harms the environment but also incurs substantial costs.

Innovation Solution

A water-saving siphon device with a tap system is installed under sinks, showers, or bathtubs, allowing collected water to be reused by redirecting it into a reservoir, which can be used for various purposes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If the original siphon is used without modification, then the drainage system remains simple and easy to operate, but water is wasted during waiting periods and rinsing activities

Engineering Contradiction:
Improvewater wasteVSAvoiddrainage system complexity
Core Design Contradiction:
Loss of substanceVSDevice complexity

Solution Approach 1:

The drainage system is segmented into two separate pathways: a primary drainage path for waste water and a secondary recycling path for clean water. The siphon device is divided into functional sections including a reservoir, tap system, and directional control mechanisms, allowing independent operation of water collection and drainage functions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A twist lock mechanism serves as an intermediary device to control water direction. This simple mechanical mediator redirects water flow between the reservoir and drainage system based on operational needs, enabling water recycling without complex automation or multiple manual operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If a water recycling system is implemented, then water can be reused for various purposes, but installation requires modifications to the drainage system

Engineering Contradiction:
Improvewater reusabilityVSAvoidinstallation ease
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The siphon device is designed with universal applicability across different drainage systems (sink, shower, bathtub). The standardized tap system and reservoir integration allow the same basic design to serve multiple functions: water collection, direction control, and recycling, reducing the need for custom installations.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The twist lock mechanism provides self-service operation for water direction control. Users can independently redirect water flow by simply twisting the lock mechanism, without requiring professional installation assistance or complex control systems. The device is designed for DIY installation and operation.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the tap system is always open, then water is readily available for use, but contaminated water may enter the reservoir

Engineering Contradiction:
Improvewater accessibilityVSAvoidcontaminated water entry
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The tap system transitions from a static always-open state to a dynamic controllable state. The twist lock mechanism allows the tap to be opened or closed based on operational needs, enabling users to control water flow and prevent contaminated water from entering the reservoir while maintaining ease of operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The directional control mechanism provides feedback to the user about water flow status. The twist lock position indicates whether water is being directed to the reservoir or drainage system, allowing users to monitor and adjust operation to prevent contamination while maintaining accessibility.

Inventive Principle:
Principle #23Feedback
