Motor-Driven Pivot Frame for Leaning Vehicle Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting systems for vehicles that lean or change position, such as motorcycles, are complex, costly, and cumbersome to fit or retrofit, failing to effectively illuminate the road as the vehicle tilts, impacting safety.
Innovation Solution
A lighting system with a pivot frame, motor, and controller that adjusts the light emitting or reflective device's angle based on the vehicle's leaning angle, using a mount to secure to the vehicle's light fitting and a motor to rotate the pivot frame relative to the mount, ensuring consistent illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lighting system is designed to adapt to vehicle leaning angle, then illumination effectiveness is improved, but device complexity increases
Solution Approach 1:
The lighting system employs a motor-driven pivot frame that dynamically adjusts the light emitting device's angle in response to vehicle leaning angle changes. The controller receives leaning angle data from sensors and actuates the motor to rotate the pivot frame, maintaining optimal illumination orientation relative to the road surface despite vehicle banking.
Solution Approach 2:
The system incorporates sensors that continuously monitor the vehicle's leaning angle and feed this information to the controller. The controller processes this feedback and adjusts the pivot frame angle accordingly, creating a closed-loop control system that maintains effective illumination under varying vehicle positions.
2Reliability
If existing lighting systems adapt to vehicle position changes, then safety is improved, but manufacturing cost increases
Solution Approach 1:
The lighting system is divided into modular components: a mount that attaches to the vehicle, a motor, a pivot frame, and a light emitting device. This segmentation allows for standardized mass production of individual components and facilitates selective assembly, reducing overall manufacturing complexity and cost while maintaining adaptive functionality.
Solution Approach 2:
The mount is designed with universal mounting capabilities that can accommodate various headlight assembly types found in modern motorcycles. The standardized interface and adaptable mounting structure enable the same lighting system to be installed across different vehicle models, achieving economies of scale in production.
3Adaptability or versatility
If lighting system is designed for modern compact headlight assemblies, then adaptability is improved, but installation difficulty increases
Solution Approach 1:
The pivot frame provides dynamic positioning capability that allows the light emitting device to adjust its orientation within a range of angles. This dynamic adjustment compensates for variations in mounting positions across different headlight assemblies, enabling universal fitment while maintaining optimal light projection geometry.
Solution Approach 2:
The separation of the mount from the light emitting device allows for independent optimization of each component. The mount can be designed specifically for easy attachment to various headlight assemblies, while the light emitting device remains a standardized module, simplifying the overall installation process despite the need to accommodate diverse vehicle platforms.

AI summary
A lighting system for a leaning vehicle includes a pivot frame configured to be fixed to a light emitting and/or light reflective device, a mount configured to be fixed to a light fitting, and a motor attached to the pivot frame and the mount. The motor is configured to provide rotational movement of the pivot frame relative to the mount. A controller in electrical communication with the motor is configured to receive sensor data of a leaning angle of the leaning vehicle and control the motor to rotate the pivot frame to a desired angle relative to the mount based on the leaning angle.
