Electric Generator Canister Mounting for Vibration Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric generators face challenges in accommodating a canister of increased size due to space constraints, which affects the absorption-desorption performance and overall arrangement of components.
Innovation Solution
The electric generator design positions the engine at the lower part of the housing, with a coaxial alternator and fan connected to the output shaft, a fuel tank at the upper part, and a canister containing activated carbon placed between the fuel tank and the output shaft, utilizing a bracket and rubber members for secure and flexible mounting, allowing for efficient use of space and vibration absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a canister of increased size is used to improve absorption-desorption performance, then the absorption performance is improved, but the canister cannot be accommodated in the conventional arrangement position due to space constraints
Solution Approach 1:
The canister is repositioned from the conventional lateral arrangement to a vertical arrangement between the fuel tank and output shaft, utilizing the vertical dimension of the housing to accommodate the larger canister size without increasing the horizontal footprint.
Solution Approach 2:
A rubber member is introduced as a flexible mounting element that allows the canister to be securely held while accommodating variations in position and absorbing vibrations, enabling the canister to be firmly mounted in the new vertical position.
2Device complexity
If the canister is arranged in a narrow space near the engine, then the device complexity is reduced, but the canister size must be limited which restricts absorption performance
Solution Approach 1:
The canister is moved to the vertical space between the fuel tank and output shaft, utilizing previously underutilized vertical space in the housing to accommodate a larger canister without increasing overall device complexity.
Solution Approach 2:
The mounting bracket and rubber member assembly serves multiple functions: securing the canister, absorbing vibrations, and accommodating positional variations, thereby maintaining device simplicity while enabling larger canister installation.
3Reliability
If the canister is securely mounted to prevent vibrations, then the reliability is improved, but the mounting structure becomes more complex
Solution Approach 1:
A rubber member is used as a flexible mounting element that provides vibration damping and secure holding of the canister simultaneously, achieving reliable mounting without requiring a complex rigid mounting structure.
Solution Approach 2:
The mounting structure combines the bracket (rigid component) with the rubber member (flexible component) to create a composite mounting system that provides both structural support and vibration absorption in a single integrated assembly.
