Construction Machine Cab Front Console Support Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional construction machine cabs require custom-designed front consoles to fit different sizes and shapes, limiting the versatility and necessitating redesigns for various models, which complicates the mounting of electronic components and affects operator visibility.
Innovation Solution
A support structure for the front console with adjustable right and left garnishes and a fixed member system that allows for centralized mounting of electronic components, enabling fine adjustments in size and shape, secure harness wiring, and improved steering shaft support, while enhancing operator visibility through adjustable garnish heights and downward extensions of the front window.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the front console is customized for each cab size and shape, then the fit and appearance are improved, but the versatility and manufacturing complexity are worsened
Solution Approach 1:
The front console is divided into a main body portion and separate garnish portions (right and left garnishes). The main body remains standardized while the garnishes are adjusted for different cab sizes and shapes, allowing customization without redesigning the entire console.
Solution Approach 2:
The standardized main body of the front console is designed to be universally applicable across different cab types, while the adjustable garnishes provide model-specific customization. This allows one main design to serve multiple applications.
2Volume of moving object
If the front console size is reduced for small cabs, then the interior wall interference is avoided, but the electronic component mounting capacity is reduced
Solution Approach 1:
Electronic components are arranged in a centralized fashion within the main body of the front console, utilizing vertical and depth dimensions rather than only horizontal expansion. This allows compact arrangement that fits small cabs while maintaining component capacity.
3Volume of moving object
If the front console size is increased for large cabs, then the electronic component mounting capacity is improved, but the interior wall exposure and appearance are worsened
Solution Approach 1:
The garnish portions are designed as separate adjustable elements that can be modified to match different cab interior dimensions, ensuring proper fit and appearance without requiring the main console body to be oversized.
4Adaptability or versatility
If the harness is wired flexibly for different console configurations, then the adaptability is improved, but the wiring complexity and error risk are worsened
Solution Approach 1:
The harness is pre-wired along the pipe structure of the first fixed member during manufacturing, establishing a predetermined routing path that simplifies installation and reduces wiring errors while maintaining adaptability through the adjustable garnishes.

AI summary
In a cab for construction machine, a support structure for a front console is provided with a first fixed member supporting a cover member and a second fixed member supporting the first fixed member from below the first fixed member. The first fixed member is fixed to a front plate at two locations directly below both ends of a front window. The second fixed member is fixed to a floor plate.
