Hollow Under-Mount Cab Storage for Work Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional work vehicles lack sufficient space on the vehicular body frame to accommodate an increasing number of apparatus and tools, necessitating a more efficient use of available space.
Innovation Solution
A work vehicle design featuring a vehicular body frame with a cab mount forming a hollow under-mount space, an exterior cover with an opening portion, and a double-door type opening and closing cover that allows the under-mount space to be opened to the external space for increased storage and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the space below the cab is used to dispose apparatus and tools, then the accommodation space is increased, but the number of articles that can be mounted is still insufficient
Solution Approach 1:
The under-mount space is divided into front and rear segments by providing both front and rear cab mounts, each forming its own hollow space. This segmentation allows multiple separate accommodation zones, enabling mounting of more articles by utilizing both front and rear spaces independently.
Solution Approach 2:
The invention utilizes the vertical dimension by forming hollow under-mount spaces below the cab mount, and also extends in the longitudinal dimension by providing both front and rear cab mounts. This multi-dimensional space utilization significantly increases the total accommodation volume available for articles.
2Ease of operation
If an opening portion is formed in the exterior cover to access the under-mount space, then accessibility is improved, but the strength of the exterior cover is reduced
Solution Approach 1:
The opening and closing cover is divided into multiple segments (first opening and closing cover for front space, second for rear space). This segmentation allows selective opening of only the required section, maintaining the strength of the closed portions while providing necessary accessibility.
Solution Approach 2:
The opening and closing cover is designed to be movable between open and closed positions, allowing the exterior cover to dynamically adapt between providing access and maintaining structural strength. When closed, the full strength is restored; when opened, access is provided only where needed.
3Length of moving object
If the cab mount is positioned close to the vehicular body frame, then the overall vehicle size is reduced, but the under-mount space volume is decreased
Solution Approach 1:
The invention maximizes the utilization of vertical space by forming hollow under-mount spaces below the cab mount, and longitudinal space by providing both front and rear cab mounts. This multi-dimensional approach allows achieving sufficient volume without increasing the overall vehicle footprint.
Solution Approach 2:
The under-mount spaces are nested within the overall vehicle structure, utilizing the space between the vehicular body frame and the ground. This nesting approach allows maximizing accommodation volume within the existing vehicle envelope without increasing external dimensions.

AI summary
A work vehicle which can provide more accommodation space for articles on a vehicular body frame is provided. A rear cab mount on which a cab of a hydraulic excavator is mounted is mounted on a revolving frame and forms a hollow rear under-mount space. An opening portion is formed at a position corresponding to a side of the rear under-mount space in an exterior cover which laterally covers the revolving frame. A rear door body can open and close the opening portion. The rear door body opens the rear under-mount space to an external space with the opening portion being opened.
