Solution Overview

Problem

Current vision improving devices are ineffective in addressing the near triad, which includes reduction of accommodation, pupillary response, and convergence response abnormalities, and do not adequately alleviate dry eye conditions caused by meibomian gland obstruction.

Innovation Solution

A heat and steam generator designed to apply heat and steam to a broad area including the eyes and its surroundings, using a holder with a heat and steam generating member that contains an oxidizable metal, allowing steam to permeate and warm the muscles and meibomian glands, thereby improving blood circulation and tear film formation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a vision improving device releases steam at controlled temperature, then accommodation muscle function is improved, but the device is ineffective for addressing the complete near triad and dry eye conditions

Engineering Contradiction:
Improveeffectiveness for near triad and dry eyeVSAvoidcomprehensive treatment capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The holder is designed with multiple functions: it generates heat through oxidizable metal oxidation, generates steam by heating water, allows steam permeation to treat dry eye, and maintains skin temperature for extended periods. This multi-functional design enables comprehensive treatment of near triad responses and dry eye conditions simultaneously

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

Solution Approach 2:

The device separates the steam generation function from the heat generation function, with the holder containing both oxidizable metal for heat generation and water for steam generation. The holder also incorporates a steam permeable portion that allows selective steam transmission to the eye area, enabling targeted treatment

Inventive Principle:
Principle #1Segmentation

2Duration of action of moving object

If steam generation duration is extended, then treatment effectiveness is improved, but energy consumption increases

Engineering Contradiction:
Improvesteam generation durationVSAvoidenergy consumption
Core Design Contradiction:
Duration of action of moving objectVSUse of energy by moving object

Solution Approach 1:

The device changes the physical state of water from liquid to vapor through controlled heating, extending steam generation duration by maintaining optimal temperature parameters. The oxidizable metal provides sustained heat generation, and the holder design maintains thermal efficiency to prolong steam generation without proportional energy increase

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The oxidizable metal automatically oxidizes to generate heat, which self-heats the water to produce steam. This self-sustaining system extends steam generation duration without requiring external energy input, as the chemical energy stored in the oxidizable metal is converted to thermal energy and then to steam

Inventive Principle:
Principle #25Self-service
