Solution Overview

Problem

Existing vehicles require large-sized headlights to provide sufficient illumination, leading to increased weight and design challenges.

Innovation Solution

The vehicle design incorporates a dual-headlight system with elongated first front lights and downsized second front lights, where the first lights are positioned higher and more prominent, and the second lights are located lower, allowing for effective illumination while reducing the vehicle's weight by utilizing both lights to mimic the effect of a single large headlight.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If large-sized headlights are used to provide sufficient illumination, then the illumination intensity is improved, but the weight of the vehicle increases

Engineering Contradiction:

ImproveilluminationVSAvoidvehicle weight

Core Design Contradiction:

Illumination intensityVSWeight of moving object

Solution Approach 1:

The headlight system is divided into two separate components: first front lights positioned higher and second front lights positioned lower. This segmentation allows each light to be smaller in size while collectively providing sufficient illumination, thereby reducing the overall weight compared to a single large headlight

Inventive Principle:

Principle #1Segmentation

2Illumination intensity

If large-sized headlights are used to provide sufficient illumination, then the illumination intensity is improved, but the device complexity increases

Engineering Contradiction:

ImproveilluminationVSAvoidheadlight structure

Core Design Contradiction:

Illumination intensityVSDevice complexity

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The first front lights and second front lights work together as a unified illumination system. By combining the light output from both positions (higher and lower), the system achieves the illumination effect of a large headlight while using smaller, simpler components

Inventive Principle:

Principle #5Merging (Combining)

3Weight of moving object

If the second front lights are downsized, then the vehicle weight is reduced, but the illumination intensity may be insufficient

Engineering Contradiction:

Improvevehicle weightVSAvoidillumination

Core Design Contradiction:

Weight of moving objectVSIllumination intensity

Solution Approach 1:

The illumination problem is solved by adding a vertical dimension to the light arrangement. First front lights are positioned higher and second front lights are positioned lower, creating a multi-level illumination system that provides sufficient total light output while allowing each individual light to be smaller and lighter

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A vehicle includes a vehicle body frame, a front wheel, a handle, a pair of left and right first front lights, and a pair of left and right second front lights. The front wheel is supported by the vehicle body frame. The handle is located farther to the rear than a rotation axis of the front wheel, and is operated by an occupant to turn the front wheel. The pair of left and right first front lights extend linearly in the left-right direction, and are located farther to the rear than a front end of the front wheel and farther to the front than the handle. The pair of left and right second front lights are provided separately from the first front lights.
