Fuel Container Buffer Mechanism for Impact Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas combustion type driving tools transmit impacts to fuel containers, causing creasing and pinhole phenomena in the inner bags, leading to poor fuel injection and rendering the fuel container unusable, and existing solutions require additional space for spring-based buffering mechanisms.
Innovation Solution
A fuel container holding structure that incorporates a buffer mechanism within the connecting unit, using a valve body and rear end buffer member to absorb impacts without the need for external space, ensuring the fuel container is protected and maintaining a standardized design for space efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spring-based buffer mechanism is used to protect the fuel container from impacts, then the fuel container is protected from damage, but additional space is required for disposing the spring
Solution Approach 1:
The buffer mechanism is merged with the connecting unit that connects the fuel container to the tool body. The connecting unit itself is designed to function as the buffer, eliminating the need for a separate spring component and its associated space
Solution Approach 2:
The connecting unit is given multiple functions: it serves both as the connection element between the fuel container and tool body, and as the buffer mechanism for absorbing impacts. This multi-functionality eliminates the need for separate dedicated buffer 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
The buffer mechanism effectively absorbs impacts, preventing damage to the fuel container while maintaining a compact design, ensuring continuous fuel injection and facilitating maintenance, such as cleaning, without increasing the number of parts.
Implementation Method 1
a buffer mechanism to be disposed between the connecting portion and fuel container, the fuel container being supported by the buffer mechanism
