Integrated Motorcycle Handlebar Guard and Mirror Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle upgrades for off-road and dual sport motorcycles, such as hand/control guards and mirrors, are typically stand-alone units that compete for limited mounting space on handlebars, offer limited adjustment and impact protection, and do not facilitate utility upgrades, compromising safety and functionality.
Innovation Solution
An integrated system that combines hand/control guards, mirrors, and accessory mounting provisions into a multi-function unit with adjustable components, including a shaped guard for enhanced impact coverage, a stowable and adjustable rear view mirror, and modular mounting provisions for various accessories, allowing for improved comfort, protection, and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple stand-alone control accessories are mounted on handlebars, then functionality is improved, but mounting space availability deteriorates
Solution Approach 1:
The patent combines multiple control accessories (hand guard, mirror, control protectors, accessory mounts) into a single integrated assembly that mounts to the handlebar as one unit. This merging eliminates the need for multiple separate mounting locations on the handlebar while providing all the desired functionalities, directly resolving the contradiction between improved functionality and limited mounting space.
Solution Approach 2:
The integrated assembly serves multiple functions simultaneously: hand protection, mirror mounting, control protection, and accessory mounting. This multi-functionality allows a single component to replace multiple stand-alone accessories, thereby improving overall functionality while consuming minimal handlebar mounting space.
2Strength
If rigid mounting provisions are used in guard designs, then structural strength is improved, but adjustment capability deteriorates
Solution Approach 1:
The integrated assembly incorporates adjustable mounting mechanisms that allow the rider to modify the position and orientation of components (such as mirror angle and hand guard positioning) while maintaining secure structural attachment. This dynamic adjustability resolves the contradiction by enabling both structural strength through secure mounting and adaptation to rider preference through positional adjustments.
3Loss of energy
If guards rotate freely on impact, then energy attenuation is improved, but protection reliability deteriorates
Solution Approach 1:
The hand guard incorporates a controlled rotation mechanism that allows limited rotational movement to absorb impact energy while including hard stops that prevent excessive rotation. This dynamic design enables the guard to attenuate energy from minor impacts through controlled movement while maintaining reliable protection by limiting rotation to safe thresholds, resolving the contradiction between energy attenuation and protection reliability.
4Ease of manufacture
If simple bar structures are used in guards, then manufacturing ease is improved, but impact coverage deteriorates
Solution Approach 1:
The hand guard employs curved and contoured bar structures rather than simple straight bars. These curved configurations provide enhanced impact coverage by wrapping around the handlebar and control areas, increasing the protective surface area. The curved design maintains manufacturability through standard forming processes while significantly improving the coverage area compared to simple linear bar structures.
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
The integrated system reduces clutter, weight, and parts count, providing enhanced protection and functionality by increasing impact coverage, improving mirror deployment, and enabling adjustable mounting for various handlebar widths, while maintaining essential protection and safety through limited energy attenuation and adjustable mounting options.
Implementation Method 1
The swivel boss and upper handlebar clamp incorporates a hard stop, which allows limited energy attenuation in event of impact while still offering essential protection by limiting overall rotation.
