Motorcycle Brake Actuation Device Integrated Stopper Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing actuation devices for motorcycle brakes and clutches are costly, aesthetically unattractive, and require numerous separate components for assembly, which complicates maintenance and increases the risk of leakage and moisture ingress due to the use of separate screws or bolts for the tank stopper and attachment brackets.
Innovation Solution
An integrated actuation device design where the stopper and attachment brackets share threaded connection means, with a first attachment portion intercepting these connections to secure the stopper to the device body and handlebar, reducing the number of components and enhancing hermetic sealing, while a second detachable connection ensures secure attachment without affecting the hydraulic seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate screws or bolts are used to attach the stopper and attachment brackets, then the components can be independently assembled and disassembled, but the number of components increases, production and assembly costs increase, and aesthetic appeal deteriorates
Solution Approach 1:
The patent merges the stopper and attachment brackets into a single integrated component. The stopper includes an integrated attachment bracket that combines the sealing function and mounting function into one piece, eliminating the need for separate screws or bolts to attach the stopper to the housing. This reduces the total number of components and simplifies assembly while maintaining the ability to independently service the seal.
2Reliability
If separate screws or bolts are used for the stopper and attachment brackets, then each component can be secured independently, but the risk of leakage and moisture ingress increases due to multiple connection points
Solution Approach 1:
By integrating the attachment bracket into the stopper as a single piece, the patent eliminates multiple separate connection points where leaks could occur. The integrated design provides a continuous sealing surface that reduces the risk of moisture ingress and leakage compared to multiple discrete screw connections.
3Ease of repair
If multiple separate components are used for the stopper and brackets, then assembly and disassembly can be done independently, but maintenance complexity increases
Solution Approach 1:
The integrated stopper with built-in attachment bracket reduces the number of components that need to be tracked, stored, and reassembled during maintenance. While the bracket remains integrated, the design simplifies the maintenance process by reducing the total part count and eliminating the need for multiple fasteners.
4Shape
If separate attachment means are used for the stopper and brackets, then each connection can be optimized independently, but the aesthetic appeal deteriorates due to unrelated components
Solution Approach 1:
The patent creates a unified aesthetic appearance by integrating the attachment bracket into the stopper as a single molded or machined component. This eliminates the visual discontinuity caused by separate fasteners and creates a cleaner, more integrated appearance that is particularly important for visible motorcycle components.
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 reduces production and assembly costs, simplifies maintenance, and enhances the aesthetic appeal by integrating the stopper and brackets, ensuring secure attachment and hermetic sealing with fewer components, maintaining mechanical strength and preventing moisture ingress.
Implementation Method 1
the device 4 comprises a pair of threaded connection means 56, 60 connecting the attachment brackets 40 to each other so as to tighten the walls defining the housing seat 44 against the associable handlebar 16
Implementation Method 2
the stopper 36 comprises a first attachment portion 64 to constrain the stopper 36 to the device body 8, wherein the first attachment portion 64 intercepts one of the threaded connection means 56, 60 and/or the guide pin 54 to attach the stopper and hermetically seal the tank 28
Implementation Method 3
a tank of liquid 28 for the actuation of said device 4 and a pump suitable to pressurise said liquid
Implementation Method 4
an actuation lever 24 rotating around a guide pin 54 defining an actuation axis Y-Y so as to influence said pump
