Bicycle Trailer Push Handle Integrated Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multifunction bicycle trailers face issues with lighting devices that increase air resistance, interfere with folding mechanisms, are vulnerable to impact, and are easily lost due to separate component handling.
Innovation Solution
Integrating the lighting device into the push handle or its coupling, ensuring it is firmly attached and positioned, thus eliminating the need for additional attachments and reducing the risk of loss or damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lighting device is attached to the passenger compartment, then the lighting function is provided, but the air resistance increases and the folding mechanism is interfered with
Solution Approach 1:
The lighting device is merged with the push handle assembly, combining two separate functions (lighting and pushing) into a single integrated component. This eliminates the need for separate mounting on the passenger compartment, thereby reducing air resistance while maintaining lighting functionality.
2Reliability
If the lighting device is attached to the passenger compartment, then the lighting function is provided, but the device is vulnerable to impact during folding
Solution Approach 1:
By integrating the lighting device into the push handle assembly rather than mounting it on the passenger compartment, the lighting device is positioned in a location that experiences less impact stress during folding operations, thereby improving impact resistance while maintaining lighting function.
3Reliability
If the lighting device is provided as a separate component, then the lighting function is provided, but the device is easily lost
Solution Approach 1:
The lighting device is permanently integrated into the push handle assembly, eliminating the need for separate handling, attachment, or storage of the lighting component. This integration prevents loss while maintaining full lighting functionality.
4Reliability
If a pennant pole with light is used, then the lighting function is provided, but the structure becomes bulky and creates safety hazards
Solution Approach 1:
Instead of using a separate pennant pole structure, the lighting device is integrated directly into the existing push handle assembly. This eliminates the need for additional bulky components while maintaining the lighting function, thereby reducing structural complexity.

AI summary
The invention relates to a bicycle trailer, in particular for transporting children, comprising a chassis (1, 23) and a frame which is connected to the chassis for a passenger compartment. The trailer has at least two wheels (2, 21) and can be provided with a towbar (3, 22) for hitching to a bicycle and at least one third wheel in order to use the bicycle trailer as a stroller or as a jogger. The trailer has a lighting device (14, 35) and a push handle (6, 25). The aim of the invention is to provide such a bicycle trailer in which the handling of the lighting device is simplified. According to the invention, this is achieved in that at least one lighting device is integrated into the push handle or into a coupling for securing the push handle to the frame.
