Swing Arm Housing Layout for Compact Saddle-Ride Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing saddle-ride type vehicles face an increase in size when protective measures for housing structures like canisters are implemented, leading to undesirable bulkiness.
Innovation Solution
The canister and reservoir tank are positioned between the pivot shaft and rear wheel, overlapping the swing arm, utilizing the existing space efficiently and protected by the swing arm, eliminating the need for additional covering and reducing the vehicle's overall size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the housing structure is disposed in a dedicated space covered with a cover to protect it, then the housing structure is protected from foreign matter, but the size of the saddle-ride type vehicle increases
Solution Approach 1:
The swing arm serves multiple functions: it connects the rear wheel to the vehicle body frame, enables rear suspension movement, and simultaneously acts as a protective cover for the housing structure (canister and reservoir tank). By making the swing arm universal, the patent eliminates the need for separate protective covers, thereby preventing vehicle size increase while maintaining protection reliability.
2Reliability
If protective covers are added for the housing structure, then foreign matter protection is improved, but device complexity increases
Solution Approach 1:
The swing arm is designed to perform multiple functions including structural support, suspension movement, and protective covering. This multi-functionality reduces the total number of components needed, thereby simplifying the overall device structure while maintaining adequate protection for the housing structure against foreign matter.
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 prevents size increase while effectively protecting the housing structures, enhances stability by lowering the center of gravity, reduces weight, and simplifies the design by integrating the canister and reservoir tank with the vehicle's frame, improving appearance and safety.
Implementation Method 1
The housing structure is disposed between the pivot shaft and the rear wheel and at a position overlapping the swing arm in a side view of the saddle-ride type vehicle
