Bicycle Control Lever with Integrated Luminous Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle control levers with luminous indicators are not effectively integrated, making them impractical for providing both cyclist and external visibility of operational status and direction changes.
Innovation Solution
A bicycle control lever design featuring a luminous indicator positioned between an inner and outer half-shell, with the outer half-shell having a transparent region to house the indicator, allowing for irremovable association and providing visual feedback to the cyclist and external parties through LEDs or OLEDs, powered by an integrated or separate power source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If luminous indicator means are integrated into the control lever, then visibility and cyclist awareness are improved, but device complexity increases
Solution Approach 1:
The patent merges the luminous indicator means with the control lever body by integrating the indicator into the lever structure itself. The control lever (10) incorporates luminous indicator means (40) that are fixed to the lever body, combining the functions of control and visual indication into a single integrated component. This reduces the need for separate indicator devices and simplifies the overall system while maintaining improved visibility.
Solution Approach 2:
The control lever serves multiple functions: it acts as both a control mechanism for brake/derailleur operation and as a visual indication device through its integrated luminous indicator means. The lever body itself becomes a multi-functional element that provides mechanical control and optical signaling, eliminating the need for separate dedicated indicator components.
2Illumination intensity
If outer half-shell is made transparent to house luminous indicator, then visibility is improved, but structural strength may be reduced
Solution Approach 1:
The outer half-shell is designed with differentiated properties: a transparent region (28) is created specifically at the location where luminous indicator visibility is needed, while the rest of the half-shell maintains its original material properties and structural strength. This localized transparency approach allows the shell to provide both visual access to the indicator and adequate mechanical protection where required.
