Straddle-Type Vehicle Operation Pedal With Detachable Tread Surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing operation pedal systems in straddle-type vehicles, such as brake pedals, require complex adjustments for height and tread surface modifications, which are time-consuming and inconvenient, especially when driving on varying terrain, as they necessitate tools and stable workspaces, and involve replacing entire pedals for form changes.
Innovation Solution
An operation pedal system with a detachable tread surface forming member that can be easily attached or detached using a tool-free mechanism, allowing for adjustable height and shape changes without the need for tools, enabling quick adjustments on the go and preventing interference during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the height position of the brake pedal is adjusted by changing the yoke position on the push rod, then the tread surface height can be raised or lowered, but the adjustment process becomes complicated and time-consuming requiring tools like spanners
Solution Approach 1:
The brake pedal assembly is divided into separate components: the pedal body, the yoke, and the push rod. The yoke can be independently positioned at multiple discrete locations along the push rod, allowing height adjustment without complex fastening operations. Each yoke position corresponds to a specific tread surface height, enabling quick selection without tools.
Solution Approach 2:
The yoke position is made adjustable along the push rod to dynamically change the tread surface height according to driving conditions. The system transitions from a fixed height design to a variable height design, where the yoke can be repositioned between different locations on the push rod to optimize pedal height for different terrain and riding postures.
2Adaptability or versatility
If the yoke position is changed to adjust the tread surface height, then the height can be modified, but the adjustment work takes time and requires securing a flat work space
Solution Approach 1:
The adjustment mechanism is segmented into discrete, pre-defined yoke positions along the push rod. Each position can be quickly engaged without complex procedures, reducing adjustment time from minutes to seconds. The segmented design allows riders to make rapid adjustments while traveling without needing to stop in a controlled workspace.
3Adaptability or versatility
If the entire brake pedal is replaced to change the tread surface form, then the shape can be changed, but the work becomes complicated and difficult to perform while traveling
Solution Approach 1:
The brake pedal system is segmented into the pedal body and the tread surface forming member as separate components. The tread surface forming member can be independently attached or detached from the pedal body, allowing riders to change the tread form without replacing the entire pedal assembly. This modular design simplifies the change process from complex replacement to simple attachment/detachment operations.
Solution Approach 2:
The pedal body is designed as a universal base that can accommodate different tread surface forming members. The standardized interface allows various tread configurations to be mounted on the same pedal body, enabling form changes while maintaining the core pedal structure and reducing the complexity of replacements.

AI summary
An operation pedal system that is installed in a straddle-type vehicle includes an operation pedal having an arm portion and a pedal portion, and a tread surface forming member that is attached to the pedal portion to form a first tread surface above the pedal portion that receives a stepping force when a stepping operation is performed on the operation pedal. In the operation pedal system, the tread surface forming member is separate from the operation pedal, and the tread surface forming member has a body portion having a tread surface forming surface forming the first tread surface on an upper surface, and an attachment mechanism provided on the body portion for detachably attaching the tread surface forming member to the pedal portion.
