Motorcycle Frame Cover Cable Concealment and Leg Shield Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motorcycles with exposed body frame cables have a monotonous appearance and rigidity issues due to cable exposure, and existing leg shield designs suffer from decreased rigidity and deformation under wind pressure.
Innovation Solution
A frame cover with a band-plate-shaped cable crossing portion and a cable covering portion that extends along the body frame cables, along with a leg shield design featuring an opening for wind cooling supported by a rigid frame cover to maintain stiffness and prevent cable exposure, and engaging mechanisms to secure the leg shield in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If an opening is formed on the leg shield for engine cooling, then cooling efficiency is improved, but rigidity of the leg shield decreases causing deformation or fluttering
Solution Approach 1:
A support member is introduced as an intermediary element between the opening in the leg shield and the frame. This support member bridges the gap created by the opening, providing structural reinforcement to prevent deformation and fluttering while allowing the opening to remain functional for engine cooling.
Solution Approach 2:
The leg shield is designed with non-uniform structural properties - the areas around the opening are reinforced with support members to maintain rigidity where needed, while the opening itself remains open for cooling. This local reinforcement approach allows different parts of the leg shield to have different structural characteristics optimized for their specific functions.
2Ease of manufacture
If the body frame is exposed by removing the side cover, then assembly simplicity is improved, but external appearance becomes monotonous and cables are exposed
Solution Approach 1:
The frame cover is designed to integrate multiple functions into a single component: it covers the body frame for aesthetic purposes, conceals the cables that would otherwise be exposed, and provides structural support. By merging these functions, the design achieves an improved external appearance without significantly complicating the assembly process.
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 solution enhances the motorcycle's external appearance by concealing cables, maintains the rigidity of the leg shield under wind pressure, and improves cooling efficiency while preventing cable exposure and deformation.
Implementation Method 1
an opening that leads travel wind to a neighborhood of an engine is formed on a leg shield that covers the front of a driver's legs, thus cooling the engine

AI summary
A motorcycle has a frame cover that covers at least a part of a body frame. A body cover is disposed on left and right sides of the body frame. A front cover covers a region below a steering handle. A leg shield is attached to the front cover and is formed with an opening that opens toward a front part of the motorcycle to allow wind in to cool the engine. The frame cover has a cable crossing portion that extends in a direction crossing an extension direction of a cable extending along the body frame, in order to prevent exposure and projection of cables toward the outside. The frame cover also has a forwardly extending support member that is inserted into the opening of the leg shield and supports the leg shield.
