Solution Overview

Problem

Conventional flashlights and lanterns fail to provide a balanced lighting solution, as flashlights offer intense directional light but little ambient illumination, while lanterns provide ambient light but not at a distance, and neither is suitable for comprehensive area illumination or user safety.

Innovation Solution

A multi-section portable electric torch with independently controllable light emitting diodes (LEDs) in four quadrants, allowing for selective emission of light in various directions, controlled via a multi-function button or mobile device, and featuring a rechargeable design that can power other devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a flashlight is used to provide directional light, then illumination intensity at a distance is improved, but ambient light coverage deteriorates

Engineering Contradiction:

Improveillumination intensity at distanceVSAvoidambient light coverage

Core Design Contradiction:

Illumination intensityVSAdaptability or versatility

Solution Approach 1:

The torch is divided into multiple independently controllable light sections (first light section and second light section), allowing selective activation of different light groups to provide both focused directional illumination and broader ambient lighting coverage simultaneously

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The lighting system dynamically adjusts between different lighting modes (first lighting mode for directional light, second lighting mode for ambient light) based on user needs, enabling the same device to adapt to different environmental requirements

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If a lantern is used to provide ambient light, then area illumination is improved, but light focus capability deteriorates

Engineering Contradiction:

Improvearea illuminationVSAvoidlight focus capability

Core Design Contradiction:

Adaptability or versatilityVSIllumination intensity

Solution Approach 1:

The lantern function is segmented into controllable light sections that can be selectively activated, allowing the user to engage only the necessary light groups for area illumination while maintaining the option to focus light when needed

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The device combines both flashlight and lantern functionalities in a single unit, with the ability to switch between focused directional lighting and broad ambient lighting modes, making it universally applicable to both scenarios

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If light is emitted in all directions (lantern mode), then ambient light coverage is improved, but eye strain increases

Engineering Contradiction:

Improveambient light coverageVSAvoideye strain

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The lighting system dynamically switches between full 360-degree ambient lighting mode and directional lighting mode, allowing users to minimize eye strain by selecting directional lighting when ambient light is sufficient, while still providing comprehensive ambient coverage when needed

Inventive Principle:

Principle #15Dynamics

4Illumination intensity

If conventional torches are used with combustible material, then light emission is improved, but safety hazards worsen

Engineering Contradiction:

Improvelight emissionVSAvoidsafety hazards

Core Design Contradiction:

Illumination intensityVSObject-generated harmful factors

Solution Approach 1:

The mechanical/chemical combustion system is replaced with an electrical lighting system using batteries and LED bulbs, eliminating the generation of burning debris and associated safety hazards while maintaining effective light emission

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The invention eliminates the harmful aspect of combustible material by using electricity, which provides the same light emission function without the negative side effects of fire, smoke, and burning debris

Inventive Principle:

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