Solution Overview

Problem

Conventional safety helmet lighting devices primarily focus on forward lighting, failing to adequately indicate a user's location and requiring users to carry a separate laser pointer, which can be inconvenient and increase the risk of accidents, especially in dark environments.

Innovation Solution

A ring-shaped safety helmet lighting device with light-emitting portions on its entire circumference and front surface, powered by a portable battery, featuring a controller for brightness and color control, a laser pointer, and elastic close contact means for secure mounting, along with a vibration and flickering alert for low battery, and a motion sensor to conserve power.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If conventional lighting devices are provided only for forward lighting, then the user can keep eyes looking forward, but the user's location cannot be adequately indicated causing collisions with vehicles

Engineering Contradiction:
Improveforward lightingVSAvoidlocation indication
Core Design Contradiction:
Illumination intensityVSReliability

Solution Approach 1:

The lighting device is segmented into multiple independent light sources positioned at different locations on the helmet (front, rear, sides). Each light source can be controlled independently to serve different functions: forward illumination for visibility and position lights for location indication, resolving the contradiction between focused forward lighting and comprehensive location marking.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention merges multiple lighting functions into a single integrated helmet-mounted device. By combining forward-facing lights for illumination with rear and side lights for position indication, the system simultaneously achieves both forward lighting capability and comprehensive location visibility, eliminating the need for separate devices.

Inventive Principle:
Principle #5Merging (Combining)

2Loss of information

If users carry a laser pointer to indicate distant objects, then distant objects can be indicated, but users cannot freely use hands for tools and the device is inconvenient to carry

Engineering Contradiction:
Improvedistant object indicationVSAvoidhand freedom
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The laser pointer function is merged with the helmet lighting device, integrating three functions (forward lighting, position indication, and distant object pointing) into a single helmet-mounted system. This eliminates the need to carry a separate laser pointer and frees both hands for tool operation while maintaining all indication capabilities.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The helmet-mounted laser pointer provides self-service for distant object indication without requiring manual operation. The device is automatically positioned on the helmet, providing hands-free operation where the laser can be directed by head movement alone, eliminating the need for hand-held carrying and operation.

Inventive Principle:
Principle #25Self-service

3Reliability

If a ring-shaped frame with light-emitting portions on the entire circumference is mounted on the safety helmet, then the user's location can be indicated from all directions, but the device must be compatible with various helmet sizes and forms

Engineering Contradiction:
Improvelocation indicationVSAvoidhelmet compatibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The mounting mechanism incorporates elastic members that provide dynamic adaptability to different helmet shapes and sizes. The elastic components can deform and conform to various helmet contours, allowing the rigid ring-shaped frame with light-emitting portions to be securely mounted on diverse helmet forms while maintaining the complete circumferential light emission for comprehensive location indication.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The mounting system utilizes elastic members that change their physical parameters (shape, position) to adapt to different helmet geometries. By allowing the mounting mechanism to dynamically adjust its configuration through elastic deformation, the device achieves universal compatibility across various helmet sizes and forms while maintaining the integrity of the circumferential light-emitting structure.

Inventive Principle:
Principle #35Parameter changes
