Solution Overview

Problem

Conventional rainwater collection systems, such as large water butts, are complex and costly to manufacture, difficult to transport and store, pose safety hazards, and have inconvenient single outlet taps and ineffective wicking arrangements for irrigation, which are further compromised by high water pressures and aesthetic issues.

Innovation Solution

A stackable water storage system comprising modular base and lid portions with independent water reservoirs, allowing for overflow between modules, facilitating easy assembly, reduced manufacturing complexity, and providing multiple outlets for convenient watering, while minimizing drowning risks and enhancing aesthetics through foliage masking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of stationary object

If a large water butt is used to store rainwater, then the storage capacity is increased, but the manufacturing complexity and cost increase due to high water pressure requirements

Engineering Contradiction:
Improvestorage capacityVSAvoidmanufacturing complexity
Core Design Contradiction:
Volume of stationary objectVSDevice complexity

Solution Approach 1:

The water storage system is divided into multiple separate water butts stacked vertically, with each butt storing a portion of the total water volume. This segmentation allows each individual butt to be manufactured with lower pressure requirements, reducing manufacturing complexity while maintaining high overall storage capacity.

Inventive Principle:
Principle #1Segmentation

2Volume of stationary object

If a large water butt is used to store rainwater, then the storage capacity is increased, but the transport and storage difficulty increases

Engineering Contradiction:
Improvestorage capacityVSAvoidtransport and storage ease
Core Design Contradiction:
Volume of stationary objectVSEase of manufacture

Solution Approach 1:

The system uses multiple smaller water butts instead of one large butt. These smaller units are easier to transport and store when not in use. The modular design allows for flexible arrangement and easier handling during installation and maintenance while achieving the same total storage capacity.

Inventive Principle:
Principle #1Segmentation

3Volume of stationary object

If a large water butt is used to store rainwater, then the storage capacity is increased, but the safety hazard increases due to drowning risk

Engineering Contradiction:
Improvestorage capacityVSAvoiddrowning risk
Core Design Contradiction:
Volume of stationary objectVSObject-affected harmful factors

Solution Approach 1:

By dividing the total water volume into multiple separate butts, the depth of water in each individual container is reduced. This segmentation eliminates the drowning hazard associated with deep water bodies while preserving the overall water storage capacity needed for rainwater harvesting.

Inventive Principle:
Principle #1Segmentation

4Device complexity

If a conventional water butt with single outlet tap is used, then the manufacturing is simplified, but the convenience of use decreases due to single outlet location

Engineering Contradiction:
Improveoutlet configurationVSAvoidconvenience of use
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

Each water butt in the stacked system is equipped with its own outlet tap positioned at convenient heights. This segmentation of outlet functions allows multiple access points at different locations, significantly improving convenience for users while maintaining simple individual butt designs.

Inventive Principle:
Principle #1Segmentation

5Extent of automation

If a wicking arrangement is used for plant irrigation, then the automated watering function is provided, but the system reliability decreases when water level drops

Engineering Contradiction:
Improveautomated irrigationVSAvoidirrigation reliability
Core Design Contradiction:
Extent of automationVSReliability

Solution Approach 1:

The irrigation system is segmented so that each water butt has its own independent wicking arrangement connected to planters on that specific butt. This ensures that if the water level drops in one butt, the wicking system in that butt simply stops operating while other butts continue to provide irrigation, maintaining overall system reliability.

Inventive Principle:
Principle #1Segmentation

6Device complexity

If a single large water butt is used, then the structure is simplified, but the aesthetic appeal decreases

Engineering Contradiction:
Improvestructural simplicityVSAvoidaesthetic appeal
Core Design Contradiction:
Device complexityVSShape

Solution Approach 1:

The stacked arrangement of multiple water butts creates a visually interesting vertical structure that can be aesthetically pleasing in garden settings. The segmentation allows for creative configurations and the addition of planters on each level, enhancing aesthetic appeal while maintaining relatively simple individual butt structures.

Inventive Principle:
Principle #1Segmentation
