Horn Positioning Above Fork Opening for Saddle Riding Vehicle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional saddle riding type vehicles face issues with durability of the horn due to foreign substances entering through the horn bores, which also reduces the effectiveness of the warning sound transmission.
Innovation Solution
The vehicle design features a horn positioned above an opening in the body cover with a horn axis extending downward and forward, allowing the warning sound to be transmitted through a linear path and reflected onto the traveling surface, while minimizing the size of the horn bores to prevent foreign substances from entering and damaging the horn.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If horn bores are made smaller or closed to prevent foreign substances from entering, then horn durability is improved, but warning sound transmission is hampered
Solution Approach 1:
The patent extracts the horn from its traditional enclosed position and places it above the opening for receiving the front fork, allowing the horn to be visible through the opening. This extraction eliminates the need for horn bores in the front cover portion, preventing foreign substance entry while maintaining sound transmission through the open space above the opening.
Solution Approach 2:
The horn is positioned in a different spatial dimension - above the opening rather than behind the front cover portion. The horn axis extends downward and forward, creating a new spatial arrangement that allows sound to propagate forward through the opening without requiring bores through the front cover, thus resolving the contradiction between protection and sound transmission.
2Reliability
If horn bores are made smaller or closed to prevent foreign substances from entering, then horn durability is improved, but warning sound volume forward of the vehicle is reduced
Solution Approach 1:
By extracting the horn to a position above the opening and making it visible through the opening, the invention eliminates the need for sound to pass through restricted horn bores. The horn sound can now propagate directly forward through the open space, maintaining or even enhancing sound volume while preventing foreign substance contamination.
Solution Approach 2:
The opening for receiving the front fork serves as an intermediary space that allows both the front fork to pass through and the horn sound to propagate forward. This intermediary opening provides a clear path for sound transmission without requiring additional horn bores, thus maintaining sound volume while protecting the horn.
3Manufacturing precision
If the horn is positioned to allow sound transmission through horn bores, then warning sound transmission is achieved, but foreign substances can enter and damage the horn
Solution Approach 1:
The horn is extracted from the enclosed space behind the front cover portion and repositioned above the opening. This extraction removes the horn from the path of foreign substances while maintaining its sound transmission function through the open space, eliminating the need for protective horn bores that would compromise sound quality.
Solution Approach 2:
Instead of protecting the horn by adding protective structures (horn bores) that compromise sound transmission, the invention inverts the approach by positioning the horn where it is naturally protected - above the opening where it is visible through the opening. This inversion eliminates the need for protective bores while maintaining both protection and sound transmission.
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 design ensures effective transmission of the warning sound forward while protecting the horn from contamination, maintaining its durability and allowing for a compact body cover construction.
Implementation Method 1
the warning sound conveniently reflects on a traveling surface, and the warning sound after the reflection proceeds further forward

AI summary
A saddle riding type vehicle includes a head tube (33), a front fork (15), a front wheel (11), a body cover (21) having a front cover portion (41)disposed forward of the head tube and a rear cover portion (43) disposed rearward of the head tube (33) and connected to the front cover portion (41), and a horn (61) disposed between the front cover portion (41) and the rear cover portion (43). The body cover (21) has an opening (A) formed therein for receiving the front fork (15). The horn (61) is disposed above the opening (A). The horn (61) is disposed to have a horn axis (H) perpendicular to a front face (61a) thereof and extending downward and forward. At least part of the horn (61) is exposed from the opening (A) as seen from the direction of the horn axis (H).
