Cabin Assembly Retainer and Support for Lateral Impact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Construction equipment cabins connected to main frames via vibration-absorbing means lack structural stability and rigidity against external impacts, such as lateral forces, which can lead to cabin deformation and risk of injury to the driver.
Innovation Solution
A cabin assembly with a retainer system that prevents the cabin from inclining beyond a certain angle and a support system that contacts the main frame to distribute lateral loads as vertical loads, enhancing the cabin's rigidity and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the cabin is connected to the main frame through vibration absorbing means, then vibration absorption is achieved, but structural stability and rigidity against external impact deteriorate
Solution Approach 1:
The connection system is segmented into multiple functional components: vibration absorbing means for vibration isolation, retainers for angular constraint, and supports for lateral impact resistance. This segmentation allows each component to specialize in one function, resolving the contradiction between vibration absorption and impact rigidity.
Solution Approach 2:
The patent combines multiple functions into a unified cabin assembly system where vibration absorbing means, retainers, and supports work together as an integrated structure. This merging allows the system to simultaneously achieve vibration absorption, angular constraint, and impact resistance that would be difficult to accomplish with separate systems.
2Object-affected harmful factors
If the cabin is coupled to the main frame through vibration absorbing means, then vibration transmission is attenuated, but structural stability deteriorates
Solution Approach 1:
The connection system is divided into distinct functional segments: vibration absorbing means for isolating vibrations, retainers for maintaining angular stability, and supports for preventing lateral displacement. This segmentation allows each component to address a specific stability aspect without compromising vibration absorption.
Solution Approach 2:
The vibration absorbing means acts as an intermediary element between the main frame and cabin, attenuating vibration transmission while the retainers and supports provide structural stability. This intermediary approach allows the system to decouple vibration isolation from structural stability requirements.
3Object-affected harmful factors
If the cabin is connected to the main frame through vibration absorbing means, then vibration isolation is achieved, but rigidity against lateral force deteriorates
Solution Approach 1:
The lateral force resistance function is segmented from the vibration isolation function by introducing dedicated support structures that work independently of the vibration absorbing means. This allows the system to maintain vibration isolation while gaining enhanced lateral force resistance through the support and retainer mechanisms.
Solution Approach 2:
The connection system employs a composite structure combining vibration absorbing materials with rigid support and retainer mechanisms. This composite approach allows the system to simultaneously achieve vibration isolation and high rigidity against lateral forces by leveraging the complementary properties of different structural elements.
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 retainer and support systems improve the cabin's rigidity by distributing lateral loads, reducing the risk of deformation and enhancing safety by preventing excessive inclination and distributing loads effectively, thus improving the cabin's ability to withstand external impacts.
Implementation Method 1
a vibration absorbing means such as a fluid mount is disposed between the main frame and the cabin. The vibration generated in the construction equipment is absorbed by the vibration absorbing means and the vibration transmitted to the cabin is attenuated
