Rear Cab Stowing Device for Forestry Machine Shoe Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stowing devices for outdoor shoes in forestry working machines either make the operation cabin dirty, hinder visibility, or risk the shoes being lost or wet in rainy conditions, due to inadequate placement and design.
Innovation Solution
A stowing device is placed accessibly from behind the operator's seat in the cab, with a removable, slanted, and top-opened stowing part that allows for easy storage and cleaning, preventing dirt from entering the cabin and protecting the shoes from rain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the stowing device is disposed outside the cab, then the outdoor shoes can be stored, but the shoes may get wet in rainy weather or drop during work
Solution Approach 1:
The stowing device is segmented into a fixed mounting structure and a removable stowing part, allowing the stowing part to be detached for cleaning while remaining protected when installed. This segmentation enables the device to provide reliable protection during work while maintaining hygiene capability.
Solution Approach 2:
The stowing device creates a preliminary protective barrier against rain and loss by providing an enclosed storage space within the cab. The removable stowing part with its specific geometry (slanted bottom, raised rear end) prevents shoes from sliding out while being protected from external elements.
2Reliability
If the stowing device is disposed on the right front of the operator's seat, then the shoes can be stored inside the cab, but the device or shoes may hinder the sight of the transparent floor part
Solution Approach 1:
The stowing device utilizes the vertical dimension and rear space of the cab interior, positioning the stowing part behind the operator's seat rather than in the front transparent floor area. This dimensional relocation eliminates the visual obstruction problem while maintaining protective storage functionality.
3Reliability
If the stowing device is disposed on the lower to left lateral side of the operator's seat, then the shoes can be stored inside the cab, but the operator may not store the shoes immediately after taking them off
Solution Approach 1:
The stowing device is positioned in the rear of the cab where the operator naturally moves when entering and exiting. The entrance is located at the back part of the cab, so the stowing device is conveniently accessible immediately upon entry, enabling the operator to store shoes right away without additional movement.
4Device complexity
If the stowing part is fixed, then the structure is simple, but the stowing part cannot be cleaned easily when dirty
Solution Approach 1:
The stowing part is designed with dynamic characteristics - it can be removed and reinstalled. This dynamic feature allows the stowing part to be accessed for cleaning when needed, while maintaining a fixed, simple structure during normal operation. The gravitational force on the slanted bottom helps shoes remain in place during work but allows easy removal for maintenance.

AI summary
To provide a stowing device, cab, and working machine, that may hardly make an operation cabin dirty by something stored such as outdoor shoes and prevent something stored from being made dirty or lost. A stowing device is disposed accessibly from behind an operator's seat in an operation cabin on an inside of a cab comprising an entrance at a back part and comprises a stowing part capable of storing something. As it is possible to store outdoor shoes in the stowing part (40) and change into indoor shoes when getting on the operation cabin through the entrance, the operation cabin will be hardly made dirty by the dust attached on the outdoor shoes and others. As something such as outdoor shoes may be stored in the cab, something stored will not get dirty in the rainy weather and be prevented from being lost during work.
