Saddle Vehicle Stand Bracket Nested Pivot Block
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In saddle riding vehicles, existing stand support structures occupy a large space and increase weight due to the thick pivot block and stand-supporting bracket configuration, which is not optimized for space reduction and weight minimization.
Innovation Solution
A stand support structure with a pivot block formed by coupling two plates, where the stand-supporting bracket is attached to a protrusion on one plate without overlapping the second plate, featuring a semi-circular notch and support wall configuration to reduce space occupancy and weight, and a hollow section between the plates for further weight reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the stand-supporting bracket is fixed to an outer side-surface of the pivot block having a relatively large thickness in a vehicle width direction through welding, then the joining strength is improved, but the occupied space in the vehicle width direction increases and the vehicle weight increases
Solution Approach 1:
The stand-supporting bracket is repositioned from the outer side-surface to the inner surface of the protrusion of the first plate. This spatial reconfiguration in the vehicle width direction allows the bracket to utilize the hollow section space, reducing the overall occupied volume while maintaining the welding connection for joining strength.
Solution Approach 2:
The stand-supporting bracket is positioned within the hollow section of the pivot block structure. The bracket fits into the space between the first plate and second plate, effectively nesting the bracket within the existing multi-layered structure, thereby reducing the external dimensions while preserving structural integrity.

This spatial reconfiguration in the vehicle width direction allows the bracket to utilize the hollow section space, reducing the overall occupied volume while maintaining the welding connection for joining strength.
3Weight of moving object
If a hollow structure is employed in the pivot block to reduce weight, then the vehicle weight is reduced, but the structural complexity increases
Solution Approach 1:
The pivot block is divided into multiple plate members (first plate and second plate) coupled together to form a hollow section. This segmentation allows the structure to achieve weight reduction through the hollow configuration while maintaining structural integrity through the multi-plate construction.
Solution Approach 2:
The first plate is designed with a protrusion that extends farther downward than the second plate, creating an asymmetric configuration. This asymmetry enables the stand-supporting bracket to be positioned on the inner surface of the protrusion, optimizing space utilization and simplifying the overall structural arrangement.
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 reduces the occupied space and weight of the vehicle by minimizing the thickness and size of the stand-supporting bracket, enhancing joining strength, and allowing for easier manufacturing while maintaining structural integrity.
Implementation Method 1
a structure in which a hollow section is secured between both of the plate members is known
Implementation Method 2
the stand-supporting bracket has a base wall overlapping an inner surface of the protrusion of the first plate in a vehicle width direction and fixed to the protrusion through welding

AI summary
A stand support structure of a saddle riding vehicle has a main frame (14), a pivot block (17) configured to swingably support a rear wheel-supporting swing arm, and a stand-supporting bracket (27). The pivot block (17) has a first plate (17A) and a second plate (17B) attached to the main frame (14). The first plate (17A) and the second plate (17B) are coupled to each other. The first plate (17A) has a protrusion (17A-1) protruding outward farther than an extension end (17B-1) of the second plate (17B). The stand-supporting bracket (27) is coupled to a surface of the protrusion (17A-1) facing in a vehicle width direction.
