Innovation Solution

A kit comprising a filling funnel, filling pipe, ventilation pipe, and ventilation adapter that can be retrofitted into closed double-walled vessels, featuring a serrated crown, float basket, and airtight connections to enable independent watering and self-regulating irrigation, adaptable to various vessel sizes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If an integrated pipeline system is integrated into the double wall space, then self-regulating irrigation capability is achieved, but device complexity and production cost increase significantly

Engineering Contradiction:
Improveself-regulating irrigation capabilityVSAvoidproduction complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The irrigation system is divided into separate modular components: a filling funnel assembly with integrated float valve mechanism, a ventilation adapter, and a capillary wick system. These modules can be manufactured independently and assembled in the field, reducing production complexity while maintaining automation capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The complex integrated pipeline system is extracted and replaced with simpler discrete components. The filling funnel, ventilation adapter, and capillary wicks are separate elements that can be individually manufactured and then assembled together to achieve the same self-regulating irrigation function with reduced overall complexity.

Inventive Principle:
Principle #2Taking out (Extraction)

2Extent of automation

If a complete integrated solution is implemented, then self-regulating water delivery is achieved, but manufacturing cost increases

Engineering Contradiction:
Improveself-regulating water deliveryVSAvoidmanufacturing cost
Core Design Contradiction:
Extent of automationVSEase of manufacture

Solution Approach 1:

The solution uses inexpensive, easily manufactured components such as standard funnels, simple float valves, capillary wicks, and basic ventilation adapters. These components can be produced at low cost using conventional manufacturing processes, making the overall system economically viable while maintaining automated functionality.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Extent of automation

If pipeline systems are integrated within the double wall region, then automatic water regulation is achieved, but a large wall distance is required

Engineering Contradiction:
Improveautomatic water regulationVSAvoidwall distance
Core Design Contradiction:
Extent of automationVSLength of stationary object

Solution Approach 1:

The system transitions from horizontal integration within the double wall space to vertical arrangement. The filling funnel, float valve, and capillary wicks are arranged vertically, utilizing the height dimension rather than requiring extensive horizontal wall distance. This allows the system to function in vessels with limited wall thickness.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Adaptability or versatility

If existing double-walled vessels are retrofitted, then adaptability is improved, but system reliability may be compromised

Engineering Contradiction:
Improveretrofitting capabilityVSAvoidsystem reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system includes pre-assembled modules with pre-installed sealing elements, pre-positioned capillary wicks, and pre-configured float valve mechanisms. These pre-prepared components ensure proper installation and reliable operation when retrofitted into existing vessels, maintaining system integrity across different applications.

Inventive Principle:
Principle #10Preliminary action
