Solution Overview

Problem

Existing float configurations in liquids often result in overlapping floating bodies, leading to incomplete surface coverage and increased evaporation due to higher contact area with air.

Innovation Solution

A float with a regular hexagonal shape viewed from one direction, featuring a spherical body with shifted center of gravity and magnet powder on its surface, allowing non-overlapping arrangement in a honeycomb geometry to minimize air-liquid contact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If multiple hexagonal floating bodies are placed in a tank, then the liquid surface coverage is improved, but the floating bodies overlap vertically causing incomplete coverage and requiring extra units

Engineering Contradiction:
Improveliquid surface coverageVSAvoidvertical arrangement stability
Core Design Contradiction:
Area of stationary objectVSStability of the object's composition

Solution Approach 1:

The float employs asymmetric geometry with a hexagonal prism body combined with a spherical upper portion. This asymmetric shape creates stable horizontal floating orientation that prevents vertical stacking, allowing multiple floats to be arranged closely on the liquid surface without overlapping, thereby improving surface coverage efficiency

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The spherical upper portion of the float prevents interlocking between adjacent floats and eliminates vertical stacking tendency. The curved spherical shape allows floats to be positioned close together on the liquid surface without nesting, maximizing the covered area while maintaining stable horizontal arrangement

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Loss of energy

If extra floating bodies are added to reduce contact area between liquid and air, then evaporation suppression is improved, but device complexity and cost increase

Engineering Contradiction:
Improveevaporation lossVSAvoidnumber of floating bodies
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The float design integrates multiple functions into a single unit: evaporation suppression through surface coverage, magnetic particle collection on the spherical surface, and stable horizontal arrangement prevention of overlapping. This multi-functionality allows effective evaporation suppression with fewer units, reducing overall system complexity

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

Solution Approach 2:

The spherical upper portion extends the float's functionality into a new dimension by providing a collection surface for magnetic particles. This additional functional dimension allows the same float structure to simultaneously suppress evaporation and collect contaminants, eliminating the need for separate collection devices

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

AI summary

A float (10) floating in a liquid has a spherical body (12) having a spherical shape from which parts are cut off so as to form a regular hexagonal shape when viewed from one direction. In addition, the float (10) is shaped so as to form a regular hexagonal shape when viewed from the above-mentioned one direction, and the floats (10) are arranged in a honeycomb geometry to thereby reduce the contact area between the liquid and air.
