Bicycle Handgrip with Integrated Downward Light
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bicycle lights are heavy, affect maneuverability, and provide limited rear visibility, while traditional handgrips restrict gripping angles and positions, causing discomfort during riding.
Innovation Solution
A bicycle handgrip device with integrated lighting that allows adjustable gripping directions and positions, featuring a first handgrip mounted around the handlebar and a second handgrip with a light projecting downward, providing illumination to both front and rear, thus enhancing safety and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional bicycle light is clamped on the head or handlebar, then the lighting function is provided, but the weight of the light and clamp affects the maneuverability of the bicycle
Solution Approach 1:
The patent combines the bicycle light with the handgrip structure, integrating the lighting function into the existing handgrip rather than adding a separate clamped light. This merging eliminates the additional clamp weight and improves maneuverability while maintaining the lighting function.
Solution Approach 2:
The light is positioned on the handgrip and configured to project light in multiple directions (front, rear, and downward), adding dimensional versatility to the lighting function. This resolves the contradiction by providing comprehensive illumination without requiring additional clamped devices.
2Illumination intensity
If a conventional bicycle light is installed on the head or handlebar, then the lighting function is provided, but the light is directly exposed to the environment and vulnerable to wind and rain
Solution Approach 1:
The light is nested within or integrated into the handgrip structure, which provides a protective enclosure. The handgrip acts as a housing that shields the light from direct exposure to wind and rain, improving reliability while maintaining the lighting function.
3Illumination intensity
If a conventional bicycle light projects light beam only forward, then the rider can identify road conditions, but the vehicles behind cannot be notified to slow down
Solution Approach 1:
The light is configured to perform multiple functions: illuminating the road forward, warning vehicles behind, and providing downward illumination. This multi-functionality resolves the contradiction by providing both forward visibility and rear warning without requiring separate devices.
Solution Approach 2:
The light projects in multiple dimensions (forward, rearward, and downward) simultaneously, creating a comprehensive lighting pattern that addresses both forward road identification and rear vehicle warning needs.
4Device complexity
If a conventional handgrip is shaped in a circular tube, then the structure is simple, but the riders can only hold the handgrip in a single direction and cannot adjust gripping angle
Solution Approach 1:
The handgrip incorporates a rotatable joint that allows the second handgrip to rotate relative to the first handgrip, enabling dynamic adjustment of gripping angle and direction. This maintains structural simplicity while adding adaptability for different riding positions and habits.

AI summary
A bicycle handgrip device includes a first handgrip, a second handgrip, and a light. The first handgrip defines a first axis, with a first connection end and a second connection end disposed on two ends thereof. The first handgrip is mounted around the handlebar of a bicycle through the first connection end. The second handgrip is removably combined to the second connection end. The second handgrip defines a second axis perpendicular to the first axis and pointing at the ground surface. The light is disposed on the second handgrip for projecting light beam on the ground surface. Therefore, the light provides illumination and a warning light signal at different distances. Also, the handgrip device can be gripped in different directions, so that the user is allowed to adjust the gripping position for lowering habitual motion fatigue.
