Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing electric saddled vehicles face design flexibility limitations due to the placement of lights around non-rectangular lid members, which restricts aesthetic and functional enhancements.

Innovation Solution

The electric saddled vehicle incorporates a front cowl with an inclined aperture and a lid that allows for closer positioning of lights to the lid, featuring adjustable edge configurations and remote operation, enhancing design flexibility and functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If ordinary lights are positioned on the right and left of the narrower portion of the lid member, then the light placement follows conventional design, but the design flexibility is limited

Engineering Contradiction:

Improvedesign flexibilityVSAvoidlight positioning complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The light-emitting surface is configured with an outer shape that surrounds the lid member laterally and underneath, transitioning from conventional side-only placement to a multi-dimensional arrangement that includes lateral and inferior positioning. This allows the light to illuminate the lid from multiple angles, enhancing design flexibility while maintaining straightforward implementation through integrated front cowl positioning

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If the light-emitting surface is positioned closer to the lid, then design flexibility is improved, but the risk of light exposure when the lid is open increases

Engineering Contradiction:

Improvedesign flexibilityVSAvoidlight exposure to driver

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The light-emitting surface is strategically positioned closer to the lid member to enhance aesthetic integration and design flexibility, while the optical system is configured to direct illumination primarily toward the front and lateral directions. This localized positioning approach allows the light to serve both aesthetic and functional purposes without creating harmful exposure to the driver when the lid is open

AI summary

A pair of outer edges (46) are spaced in a vehicle width direction with the aperture (38) closed. The pair of outer edges (46) include a pair of separated outer ends (48) farthest in the vehicle width direction. A pair of outer lower inclined sections (52) are closer to each other at respective points lower from the pair of separated outer ends (48). A pair of inner edges (58) are opposed to the pair of outer edges (46). The pair of inner edges (58) include a pair of separated inner ends (60) farthest in the vehicle width direction. A pair of inner lower inclined sections (64) are closer to each other at respective points lower from the pair of separated inner ends (60).
