Motorcycle Airbag Connector Protection via Intermediary Buffer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In airbag apparatuses for motorcycles, the connector connecting the harness to the igniting section of the inflator often receives external forces due to the compact housing design, leading to potential interference and damage during assembly or operation.
Innovation Solution
An interference-avoiding device is integrated between the housing body and the connector, using a rigid or cushioning material to prevent direct contact and reduce external forces applied to the connector, ensuring safe operation and assembly by blocking or reducing external forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the housing body is made compact-sized to reduce the overall size of the airbag apparatus, then the productivity and space efficiency are improved, but the space between the housing body and the inflator becomes narrow, increasing the likelihood of interference with the connector and causing external forces to be applied to it
Solution Approach 1:
A buffer member is introduced as an intermediary component between the housing body and the connector. This buffer member absorbs or reduces external forces transmitted from the housing body to the connector, preventing damage while allowing the housing to maintain a compact size. The buffer member acts as a mediator that protects the connector without requiring additional space in the housing design.
2Quantity of substance
If the inflator is increased in size to accommodate larger airbag requirements, then the airbag expanding capability is improved, but the space available in the compact housing body is reduced, increasing the risk of interference with the connector
Solution Approach 1:
The buffer member serves as a spatial mediator that allows the inflator to be positioned closer to the housing body wall while still protecting the connector from interference. This enables the housing to accommodate larger inflators without increasing the overall apparatus size, as the buffer member manages the spatial relationship between components.
3Device complexity
If the connector is positioned closer to the housing body to optimize space utilization, then the device complexity is reduced, but the connector becomes more susceptible to external forces and interference from the housing body
Solution Approach 1:
The buffer member is a simple component that provides reliable protection to the connector without adding significant complexity to the overall device. By positioning the buffer member between the housing body and connector, the design maintains simplicity while ensuring the connector is protected from external forces during assembly and operation.
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
The interference-avoiding device effectively suppresses external forces on the connector, enhancing the safety and reliability of the airbag apparatus by preventing damage and ensuring proper function during collisions and assembly processes.
Implementation Method 1
an interference-avoiding device is intervened at an area between an opposing portion facing the connector in each portion of the housing body and the connector... effectively suppresses external forces on the connector

AI summary
An technique is provided for suppressing external force received by a connector from a housing body side, in an airbag apparatus for use in a motorcycle, which has a construction housing an inflator for generating gas for expanding an airbag at a gas-generating section, and a connector for connecting a harness for supplying electric current to an igniting section of the inflator in the housing body. In one form, an airbag apparatus mounted on a two-wheeled motor vehicle is constructed to prevent the retainer wall portion from directly interfering with a connector by intervening a vertical extending portion of a lower holder that holds a lower portion of an inflator at a space between the retainer wall portion and the connector.
