Movable Motorcycle Headlamp Grid for Impact Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective grids for motorcycle headlamps reduce lighting capacity due to partial screening of the light beam, posing type-approval issues as they do not meet light engineering standards in some countries.
Innovation Solution
A protective grid for motorcycle headlamps with movable grid elements that can be switched between a work configuration to intercept impacts and a rest configuration to avoid obstructing the light beam, using rotating and locking mechanisms to maintain light beam integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective grid is associated with a motorcycle headlamp, then the headlamp is protected from impacts with external bodies, but the light beam is narrowed or partially screened, reducing the lighting capacity
Solution Approach 1:
The protective grid is designed with movable grid elements that can dynamically change their position between a protective configuration (intercepting impacts) and a retracted configuration (avoiding obstruction of light). This dynamic adaptability allows the system to resolve the contradiction by providing protection only when needed, thereby maintaining lighting capacity during normal operation.
2Reliability
If a protective grid is fitted with a headlamp, then the headlamp is protected from damage, but the headlamp does not meet type-approval conditions for light engineering
Solution Approach 1:
The movable grid elements enable the protective grid to adapt its configuration based on operational requirements. When in the retracted position, the grid does not obstruct the light beam, allowing the headlamp to meet type-approval conditions. When in the protective position, it provides damage protection. This adaptability resolves the contradiction between protection and regulatory compliance.

AI summary
Protective grid (20) adapted and configured to be coupled to a vehicle headlamp (10), wherein the vehicle headlamp (10) is adapted and configured to emit a light beam, the protective grid (20) comprising: - at least one grid element (21); and - coupling means (22,23) for operatively coupling the grid element (21), directly or indirectly, to said vehicle headlamp (10). The coupling means, when the protective grid (20) is operatively coupled to said vehicle headlamp, are adapted and configured for allowing the grid element to be moved such that the grid element can be displaced from a work configuration to a rest configuration, wherein in the work configuration the grid element is such to intercept the light beam and wherein in the rest configuration the grid element is placed so that it does not intercept the light beam. The protective grid (20) comprises locking means configured to keep said at least one grid element (21) in said rest and/or work configuration during motion of the motorcycle.
