Bicycle Light Controls for Fast Mode and Brightness Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern bicycle lights lack improved usability and adjustability, especially in challenging conditions, such as those encountered during sports cycling.
Innovation Solution
A bicycle light device with two separate control means, a first control means for switching between lighting modes and a second control means for adjusting light intensity, allowing quick and ergonomic mode changes through rotation, is provided.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single switch is used to control multiple lighting modes, then the device complexity is reduced, but the ease of operation deteriorates because the user must cycle through all modes to reach the intended setting
Solution Approach 1:
The control function is segmented into two separate control means: a first control means for switching between lighting modes and a second control means for adjusting light intensity. This segmentation allows each control means to perform its specific function independently, enabling the user to quickly switch between modes without cycling through all intensity levels, thereby improving ease of operation while maintaining acceptable device complexity
Solution Approach 2:
The control interface is expanded from a single-dimensional switch to a two-dimensional control system with separate controls for mode selection and intensity adjustment. This dimensional separation allows users to independently adjust each parameter, significantly improving operational efficiency and ease of use
2Productivity
If a button switch is used for mode selection, then the device complexity is low, but the ease of operation deteriorates because pressing the button repeatedly to cycle through modes is time-consuming
Solution Approach 1:
The second control means is designed to be rotatable, providing dynamic control for intensity adjustment. This rotational mechanism allows users to quickly adjust intensity without repeated pressing actions, improving both productivity and ease of operation. The rotational control enables intuitive adjustment in any direction, making the system more responsive to user needs
3Ease of operation
If the longitudinal axis of the light device is parallel to the handlebar axis, then the mounting is simple, but the usability deteriorates because the control means are harder to access and manipulate
Solution Approach 1:
The light device is mounted with its longitudinal axis perpendicular to the handlebar axis, creating an asymmetric orientation that positions the control means in more accessible locations. This asymmetric mounting configuration allows users to easily access and manipulate the control means while riding, significantly improving usability. The perpendicular orientation ensures that controls are within the natural reach and visibility of the rider

AI summary
A bicycle light device is provided. The bicycle light device comprises a light arranged at a front side of a housing of the bicycle light device. The bicycle light device further comprises a first control means configured for switching the light between a plurality of lighting modes, and a second control means configured for being rotated around a rotational axis of the second control means, thereby changing an intensity of light to be emitted by the light. The second control means is arranged at a surface of the at least one surface such that the rotational axis of the second control means is substantially perpendicular to the longitudinal axis of the light device.
