Cabin Front Plate Attachment for Working Machine Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cabin designs for working machines, such as construction and agricultural machines, face obstacles in forward and downward visibility due to the placement of the front plate supporting the lower edge of the front glass, which limits the driver's field of view and requires a plate with significant vertical width for structural support.
Innovation Solution
The cabin device addresses this by fixing the attachment body to the vertically intermediate portion of the front plate, positioning the lower part of the front plate above the front cover, and extending the right and left supports below the attachment body to enhance visibility and structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the lower part of the front plate is fixed to the attachment body, then the supporting strength of the front plate is improved, but the forward and downward visibility from the driver's seat is obstructed
Solution Approach 1:
The patent changes the attachment position from the lower part of the front plate to the vertically intermediate portion of the inner surface, effectively utilizing the vertical dimension to resolve the conflict between structural strength and visibility requirements
Solution Approach 2:
Instead of fixing the front plate to the attachment body at the lower edge as in conventional designs, the patent inverts the attachment approach by fixing the attachment body to the inner surface of the front plate at an intermediate height, thereby achieving both strength and visibility
2Strength
If a plate material with large vertical width is used for the front plate, then the supporting strength is improved, but the device complexity and space occupation increase
Solution Approach 1:
The patent moves the attachment point upward to the vertically intermediate portion, utilizing vertical positioning to achieve structural strength without increasing the overall vertical width of the front plate, thus simplifying the device configuration
3Ease of operation
If the lower edge of the front glass is positioned close to the stepped part, then the forward and downward visibility is improved, but the supporting strength of the front plate is reduced
Solution Approach 1:
The patent utilizes the vertical dimension by attaching the attachment body to the vertically intermediate portion of the inner surface, allowing the front glass to be positioned closer to the stepped part for improved visibility while the attachment body provides structural support at a higher location

AI summary
A cabin is mounted on a device frame, and hydraulic equipment is placed on a pedestal of the device frame. In this configuration, an attachment body of a front lower part of the cabin is disposed and attached onto an installation part on a front part of the pedestal; providing a front cover between the front part of the pedestal and the front lower part of the cabin for covering forward and outward of the hydraulic equipment; and providing a front plate on the front lower part of the cabin for supporting a lower edge of a front glass. A vertically intermediate portion of an inner surface of the front plate is fixed to the attachment body, and a lower part of the front plate is placed on an upper side of the cover to thereby cover forward and upward of the installation part of the pedestal.
