Work Vehicle Cabin Mounting Plates for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cabin apparatuses for moving vehicles face instability and vibration issues due to fixed mounting on rear axle cases, especially when the transverse width is reduced, leading to potential swinging and instability.
Innovation Solution
The cabin apparatus features a pair of left and right mounting plates protruding outward from the bottom ends of the mounting braces, which are fixedly mounted on the rear axle cases via vibration-proof members, with stopper pieces to restrict vertical vibration, ensuring stable installation even with a narrow transverse width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the transverse width of the cabin apparatus is reduced, then the cabin apparatus can be made more compact, but the rear side becomes unstable and prone to vibration and swinging
Solution Approach 1:
The mounting plates extend in the transverse direction (another dimension) beyond the width of the cabin apparatus body. This dimensional extension allows the mounting interface to be wider than the cabin structure itself, providing stable mounting without increasing the overall cabin width. The mounting plates create a wider base of support in the transverse dimension while the cabin maintains its compact form.
Solution Approach 2:
The mounting system is segmented into separate components: the cabin apparatus body and the extending mounting plates. This segmentation allows the mounting function to be separated from the cabin structure, enabling the mounting plates to extend transversely for stable mounting while the cabin itself maintains a narrow, compact width for maneuverability.
2Stability of the object's composition
If the mounting width is increased to prevent vibration, then the cabin apparatus becomes more stable, but the transverse width of the cabin apparatus increases
Solution Approach 1:
The solution resolves this contradiction by using the mounting plates to extend the mounting width in the transverse dimension without increasing the cabin apparatus width in the same dimension. The mounting plates create a wider mounting interface that is distinct from the cabin body dimensions, allowing stable mounting while maintaining a compact cabin form factor.
Solution Approach 2:
By segmenting the mounting function into separate mounting plates, the patent allows the mounting interface width to be independent of the cabin apparatus width. The mounting plates can be designed with sufficient transverse extension for stable mounting while the cabin body maintains its required narrow width for operational maneuverability.
3Ease of manufacture
If vibration-proof members are used for mounting, then the cabin apparatus can be installed, but the rear side becomes unstable and prone to wide swinging
Solution Approach 1:
The mounting system is segmented into vibration-proof members for shock absorption and mounting plates for structural stability. The vibration-proof members handle vertical vibrations and shocks, while the extending mounting plates provide a wide transverse mounting base that prevents swinging and lateral instability, combining the benefits of both vibration isolation and structural stability.
Solution Approach 2:
The patent merges two functions into a single mounting system: the vibration-proof members provide shock absorption and the extending mounting plates provide lateral stability. This combination allows the rear side of the cabin apparatus to be stably supported while still accommodating vibrations, resolving the instability issue that occurred with vibration-proof members alone.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration stabilizes the cabin apparatus by widening the transverse installation width and preventing wide vibrations or swinging, allowing for stable installation and maintaining structural rigidity even when the transverse width is narrowed.
Implementation Method 1
vibration-proof members having elasticity be provided, and that the pair of left and right mounting plates be fixedly mounted on the respective left and right rear axle cases via the vibration-proof members
