Cabin Floor Mat Layout for Work Vehicle Footrest Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work vehicles often have cabin designs that restrict foot space, leading to discomfort for operators due to tight footrest angles and limited space, which can cause strain on the lower limbs.
Innovation Solution
A cabin frame design with a slant frame and floor mat configuration that includes a slant mat portion and bottom mat portion, forming angles that allow for a more spacious footrest area, reducing strain by providing a larger area for foot placement.

Engineering Contradiction Analysis
1Area of stationary object
If the footrest area is made compact to reduce cabin space occupation, then the cabin space efficiency is improved, but the operator comfort deteriorates due to tight footrest angles and limited space causing lower limb strain
Solution Approach 1:
The floor mat is divided into multiple segments: a bottom mat portion on the bottom frame and a slant mat portion on the slant frame. This segmentation allows each portion to be optimized independently - the bottom mat provides a stable base area while the slant mat creates an inclined footrest surface, together forming a spacious footrest area without occupying excessive cabin space.
Solution Approach 2:
The footrest area is extended into the vertical dimension by utilizing the inclined slant frame structure. The slant mat portion is inclined relative to the bottom mat portion, creating a three-dimensional footrest space that provides both horizontal area and vertical clearance for operator comfort without increasing the horizontal footprint.
2Ease of operation
If the footrest area is expanded to improve operator comfort, then lower limb strain is reduced, but the cabin space occupation increases
Solution Approach 1:
The floor mat is designed with different local qualities - the bottom mat portion provides a flat, stable surface for foot placement, while the slant mat portion provides an inclined surface that accommodates the natural angle of foot rest. This local differentiation optimizes comfort in the footrest area without requiring uniform expansion of the entire floor area.
3Area of moving object
If the slant frame angle is increased to create more footrest space, then the foot placement area is enlarged, but the structural stability of the cabin frame may be compromised
Solution Approach 1:
The slant frame is designed with an optimized inclination angle that balances two requirements: it is steep enough to create sufficient footrest area and vertical clearance, but not so steep as to compromise structural stability. The angle is dynamically optimized to achieve the minimum required footrest space while maintaining frame rigidity.

AI summary
A work vehicle includes a cabin frame defining a cabin interior, and a floor mat placed on the cabin frame. The cabin frame includes a floor frame, a front frame, and a seat support frame. The floor frame includes a bottom frame having a flat shape that defines a bottom floor surface facing the cabin interior. The floor mat includes a slant mat portion having a second mat surface facing the cabin interior, and a bottom mat portion having a first mat surface facing the cabin interior. A first angle formed by the first mat surface and the second mat surface is larger than a second angle formed by the bottom floor surface and a plane defined to include a first straight line representing a boundary between the bottom frame and a slant frame and a second straight line representing a boundary between the slant frame and the front frame.
