Parking Lever Lengthening Without Grip Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing saddle type vehicles face challenges in reducing the operating force required for the parking brake while maintaining a compact design, as lengthening the parking lever to reduce this force interferes with surrounding components and limits space for other members.
Innovation Solution
A parking operator system that includes a lever bracket with a holding section for the parking lever, a switch box, a lever lock mechanism, and a knuckle visor, allowing the parking lever to be extended without interfering with the grip section or other components, and featuring a parking switch and indicator on the meter case for improved usability and assembly efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the parking lever is lengthened to reduce operating force, then the operating force is reduced, but the space for surrounding members is reduced
Solution Approach 1:
The parking lever is repositioned from a location near the grip section to a location forward of the handle bar, utilizing the longitudinal dimension of the vehicle. This dimensional relocation allows the lever to be lengthened in the lateral direction without encroaching on the space near the grip section, thus reducing operating force while preserving space for surrounding members.
2Force
If the parking lever is lengthened to reduce operating force, then the operating force is reduced, but the arrangement space for other members is reduced
Solution Approach 1:
By relocating the parking lever forward of the handle bar, the patent creates additional spatial separation between the lever and other members such as the grip section, switch box, and knuckle visor. This dimensional redistribution of space allows for a longer lever arm while maintaining adequate clearance and arrangement space for other vehicle components.
3Ease of operation
If the parking lever is positioned closer to the grip section, then it is easier to operate, but it interferes with the gripping operation
Solution Approach 1:
The patent resolves this contradiction by positioning the parking lever in a different spatial location (forward of the handle bar) rather than optimizing for proximity to the grip section. This relocation eliminates interference with gripping operations while the lever remains accessible for operation, though perhaps requiring slight hand movement forward to reach.
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
Enables the parking lever to be lengthened without affecting surrounding members, reducing operating force while maintaining space for other components, and providing improved ease of use and assembly efficiency, along with enhanced visibility of the parking brake status.
Implementation Method 1
A lever lock mechanism is provided between the parking lever and the lever bracket to restrict the return of the parking lever when the parking brake is activated. The lever lock mechanism includes a lock lever and a stopper member. The lock lever is provided on the parking lever in a swingable manner. The stopper member is provided on the lever bracket to engage with the lock lever.

AI summary
A saddle type vehicle includes a parking operator for allowing the lever to be lengthened without affecting the surrounding members. A parking lever is arranged more forward than the tip of a first finger of an operator when the first finger is fully extended forward. Therefore, there is no concern that the hand holding the left grip section may touch the parking lever. Thus, the lever can be sufficiently lengthened. In addition, the parking lever is sufficiently far from the grip section toward the vehicle front. As a result, there is no concern that the parking lever may interfere with a normal gripping operation. In addition, a handle switch or other part can be readily arranged on a switch box on the base portion of the grip section without being affected by the parking lever.
