Solution Overview

Problem

Conventional guide lamps on vehicles fail to effectively communicate the vehicle's direction changes to drivers in adjacent or rear vehicles, particularly in dead zones, leading to potential accidents due to inadequate light distribution and pattern recognition.

Innovation Solution

A guide lamp apparatus that divides light from a single source into multiple beams using a prism lens and convex lenses to form patterned images on the road surface, improving visibility of the vehicle's direction and intention to other drivers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If light from a single source is simply illuminated outside through a lens, then the structure is simple, but the light distribution pattern is insufficient to convey directional information to drivers in dead zones

Engineering Contradiction:
Improvedirectional informationVSAvoidlens structure
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent divides a single light beam into multiple separate light beams using a light division lens (prism), creating distinct light paths that project directional information. This segmentation of light enables drivers in dead zones to perceive the vehicle's intended direction through multiple separated light patterns on the road surface, resolving the information loss problem while maintaining reasonable structural complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a light division lens (prism) as an intermediary optical element between the light source and the road surface. This intermediary component transforms the single light beam into multiple directed beams, serving as a mediator that encodes directional information into the light distribution pattern, thereby preventing information loss without requiring complex electronic or mechanical systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Illumination intensity

If light is simply illuminated through a lens without division, then the device complexity is low, but the visibility of vehicle direction and intention to other drivers is insufficient

Engineering Contradiction:
Improvepatterned image visibilityVSAvoidoptical system
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The light division lens segments the illumination into multiple distinct beams that form recognizable patterns on the road surface. This segmentation enhances visibility by creating spatially separated light patterns that clearly indicate directional information, making the vehicle's intention more visible to drivers in dead zones while using a relatively simple optical configuration.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

While the patent primarily uses spatial separation rather than color changes, the light division lens creates distinct spatial patterns that serve a similar information-encoding function. The separated light beams form recognizable patterns on the road surface that convey directional information, enhancing visibility without requiring complex multi-color systems.

Inventive Principle:
Principle #32Color changes

3Loss of information

If multiple light sources are used to create patterned images, then the directional information is clear, but the device complexity and cost increase

Engineering Contradiction:
Improvedirectional informationVSAvoidnumber of light sources
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

Instead of using multiple light sources, the patent segments the light from a single source using a light division lens (prism). This approach achieves the same directional information transmission as multiple light sources would provide, but with reduced complexity and cost by using one light source combined with an optical segmentation element rather than multiple independent light sources.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The light division lens creates multiple copies of the single light beam, directing them along different paths to form patterns on the road surface. This optical copying approach achieves the effect of multiple light sources using a single source, reducing device complexity and cost while maintaining clear directional information transmission.

Inventive Principle:
Principle #26Copying

4Loss of information

If a light division lens is used to divide light into multiple beams, then directional information is conveyed, but the light efficiency may be reduced due to multiple optical interfaces

Engineering Contradiction:
Improvedirectional informationVSAvoidlight efficiency
Core Design Contradiction:
Loss of informationVSLoss of energy

Solution Approach 1:

The patent optimizes the optical parameters of the light division lens (prism), including its geometry, material properties, and surface angles, to minimize light loss at each interface. By carefully designing these parameters, the system achieves effective light division for directional information transmission while minimizing energy loss through reflection and refraction at multiple optical interfaces.

Inventive Principle:
Principle #35Parameter changes
