Movable Hand Protection Shield for Motorcycles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand protection devices for vehicles either solely provide protection or offer comfort features like wind and weather protection, which are not adjustable and may be excessive in certain conditions, failing to combine both functions effectively.
Innovation Solution
A hand protection device with a rigid protective bar connected to the handlebar and a movable extension element that can be adjusted in multiple positions without tools, allowing for variable aeration or protection of the hands from the slipstream or rain, enhancing both protective and comfort functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hand protection devices are designed as rigid bars with only protective function, then protection reliability is improved, but comfort function deteriorates
Solution Approach 1:
The hand protection device is divided into a protective bar and a separate shield element. The protective bar provides reliable structural protection, while the shield element can be independently positioned to provide comfort protection against wind and weather. This segmentation allows each component to fulfill its specific function without compromising the other.
Solution Approach 2:
The shield element is designed to be movable relative to the protective bar, allowing the rider to dynamically adjust the level of comfort protection based on weather conditions and personal preference. The shield can be positioned in different locations or removed entirely, providing adaptability while maintaining the reliable protective function of the bar.
2Adaptability or versatility
If hand protection devices include comfort functions for wind and weather protection, then adaptability is improved, but device complexity increases
Solution Approach 1:
The shield element serves multiple functions: it provides protection against wind and weather when positioned in front of the rider's hand, and can be moved out of the way when not needed. This multi-functionality allows a single component to address both comfort and protective needs without requiring separate dedicated elements for each function.
Solution Approach 2:
The comfort function is extracted as a separate shield element that can be independently positioned or removed, rather than being integrated into the main protective bar structure. This extraction allows the comfort feature to be added without fundamentally complicating the core protective structure.
3Reliability
If shield is fixed rigidly to handlebar, then protection reliability is improved, but rider safety deteriorates due to hand trapping risk
Solution Approach 1:
The shield element is designed with movable connections that allow it to move away from the rider's hand in the event of a crash or sudden movement. This dynamic design eliminates the hand trapping risk associated with rigidly fixed shields while maintaining the protective function during normal riding conditions.

AI summary
A hand protection device for a handlebar of a vehicle is provided. The hand protection device includes a protective bracket that can be rigidly connected to the handlebar of the vehicle, and an extension element that is movably arranged relative to the protective bracket. The extension element can be fixed relative to the protective bracket in at least a first position and in a second position which is different from the first position. More than one extension element may be provided, and the extension element second positions may be above or below the handlebar. The vehicle may be a motorbike or a scooter.
