Motorcycle Headlight Carrier Layout for Stable Light Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing headlight designs for single-track vehicles, particularly motorcycles, suffer from high component count, reduced mechanical stability, and difficulty in replacing defective light elements due to separate filaments or semiconductor elements for position lights, which also limit light distribution adjustment.
Innovation Solution
The positioning of at least one low beam and one high beam light elements behind at least two position light elements on a light element carrier, combined with a transmissive and reflective optical element system, allows for adjustable and symmetrical light distribution, improved heat dissipation, and reduced heat transfer between elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate filament lamps or semiconductor light elements are used for position light, then position light function is achieved, but component count increases and mechanical stability decreases
Solution Approach 1:
The patent combines multiple light elements (low beam, high beam, and position light) onto a single lighting element carrier. This merging of previously separate components into one integrated unit reduces the overall component count, improves mechanical stability, and enhances the tightness of the headlight assembly while maintaining all required lighting functions.
Solution Approach 2:
The lighting element carrier serves as a universal platform that accommodates multiple types of light elements for different lighting functions (low beam, high beam, position light). This multi-functional design eliminates the need for separate mounting structures for each light element, thereby reducing component count and improving mechanical stability.
2Ease of repair
If multiple separate light elements are used, then all lighting functions are achieved, but replacing defective light elements becomes more difficult
Solution Approach 1:
By merging multiple light elements onto a single carrier unit, the patent creates a modular assembly that can be replaced as one unit. This significantly simplifies maintenance and repair operations, as technicians no longer need to handle and replace individual light elements separately, thereby improving ease of repair while maintaining all lighting functions.
3Adaptability or versatility
If position light element is arranged in reflector area, then position light is achieved, but light distribution adjustment is limited
Solution Approach 1:
The patent positions the position light element on the front end region of the lighting element carrier, extending in the longitudinal direction, rather than arranging it within the reflector area. This spatial reconfiguration in a different dimension allows for flexible light distribution adjustment while simplifying the reflector design and eliminating the need for special reflector configurations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enables flexible light distribution, enhanced mechanical stability, easier maintenance, and reduced energy consumption by allowing independent adjustment of light elements and effective heat dissipation.
Implementation Method 1
a transmissive optical element is arranged around the at least two position light elements in the end region, by which the light distribution of the at least two position light elements can be influenced
Implementation Method 2
a reflective optical element is arranged around the at least two position light elements in the end region, by which the light distribution of the at least two position light elements can be influenced
Implementation Method 3
the at least one low beam light element and the at least one high beam light element are arranged behind the at least two position light elements, in relation to the longitudinal direction, so that heat dissipation is improved and heat transfer between the light elements is reduced
