Solution Overview

Problem

There is a lack of effective methods and equipment to improve the physiological state of domesticated animals, particularly in enhancing brain function and overall well-being, leading to increased medical care costs and reduced quality of life for pets like cats and dogs.

Innovation Solution

Irradiating domesticated animals with light of a specific wavelength region, such as violet light, continuously or in pulses at a specific frequency, using a light irradiating apparatus controlled by a controller to enhance physiological state.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If supplements are used to improve brain function of aged cats and dogs, then physiological state is improved, but device complexity and cost increase

Engineering Contradiction:
Improvephysiological stateVSAvoidequipment complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical/electronic brain stimulation equipment with a simple light irradiation system. Instead of using sophisticated devices to stimulate brain activity, the invention uses violet light irradiation apparatus that can be integrated into everyday items like glasses or headbands, dramatically simplifying the system while maintaining effectiveness in improving physiological state of aged animals

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The light irradiation apparatus is designed to serve multiple functions: it can be worn as eyeglasses, headbands, or integrated into existing accessories, allowing it to work for different animals and different durations. This universal design reduces the need for multiple specialized devices, thereby reducing overall system complexity and cost

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

2Reliability

If medical care is provided to aged pets, then quality of life is maintained, but cost increases

Engineering Contradiction:
Improvequality of lifeVSAvoidmedical care cost
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent applies preliminary action by using light irradiation to proactively improve brain function and physiological state before serious health issues develop. By regularly irradiating aged animals with violet light, the system prevents cognitive decline and age-related conditions, reducing the need for expensive medical interventions later

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention converts the harmful effects of aging (brain function decline, cognitive impairment) into a beneficial outcome through light irradiation. By targeting the root cause of age-related deterioration, the system transforms a problematic state into an improved physiological condition, reducing reliance on costly medical care

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)
