Saddled Vehicle Airbag Control Device Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In saddled vehicles, the airbag control device is vulnerable to impact and susceptible to water exposure, as existing configurations do not adequately protect it from both mechanical stress and environmental moisture.
Innovation Solution
The airbag control device is strategically positioned within the body frame's protective region, above the intake device's lower end, and housed in an L-shaped retainer with the inflator, ensuring it is compactly and securely fixed, while being elevated to avoid water ingress during operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a traditional chain drive or belt drive is used to transmit power from the drive wheel to the driven wheel, then the mechanical structure becomes complex and maintenance-intensive, but the patent seeks to eliminate these complex mechanical components
Solution Approach 1:
The patent replaces the traditional mechanical chain drive or belt drive system with a magnetic coupling system. The drive wheel includes a first permanent magnet array, and the driven wheel includes a second permanent magnet array, which magnetically couple to transmit power without direct mechanical contact. This eliminates chains, belts, and associated mechanical components while maintaining reliable power transmission through magnetic fields.
2Weight of moving object
If the saddled vehicle is designed to be lightweight for portability, then the structural strength and stability may be compromised, but the patent aims to achieve both lightweight design and structural integrity
Solution Approach 1:
The patent employs a modular frame structure where each component is optimized for its specific function and load requirements. The frame includes a handle assembly, seat assembly, and wheel assemblies connected through optimized joint designs. This localized optimization allows the overall structure to be lightweight while maintaining structural strength where needed, rather than uniformly strengthening the entire vehicle.
Solution Approach 2:
The patent utilizes composite material construction for the frame and components, combining materials with different properties to achieve both lightweight characteristics and structural strength. The modular design allows selection of appropriate materials for each component based on its specific mechanical requirements, optimizing the strength-to-weight ratio throughout the vehicle structure.
3Adaptability or versatility
If the vehicle uses a fixed gear ratio transmission system, then the mechanical structure is simpler, but the adaptability to different terrains and speeds is reduced
Solution Approach 1:
The patent incorporates a dynamic transmission system with variable gear ratios that can be adjusted during operation. The transmission assembly includes multiple gear sets and a shifting mechanism that allows the user to change gear ratios to optimize performance for different terrains and speeds. This dynamic adaptability is achieved through a compact design that integrates the gear mechanisms within the driven wheel assembly.

Function Achieved in This Case
This configuration effectively shields the airbag control device from impacts and prevents water exposure, ensuring reliable operation and deployment of the airbag while maintaining a compact and efficient design.
Implementation Method 1
the drive wheel and the driven wheel are magnetically coupled to one another such that rotation of the drive wheel about the first axis magnetically couples rotation of the driven wheel about the second axis
