Controller Assembly Bracket Design for Limited Cab Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing arrangement of the controller main body for processing position information in work machines is not easily installable due to limited space behind the operator's seat, where additional equipment like air conditioners are already present, making it difficult to connect and mount the controller effectively.
Innovation Solution
A controller assembly with a base plate, bracket, and vibration damping members, where the bracket's flange and side portions allow easy assembly by inserting into the base plate's through hole, enabling the controller main body to be mounted from the side and utilizing existing equipment space efficiently, with the option to mount two controller main bodies using one base plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the controller main body is installed behind the operator's seat, then it can be connected to the display and positioned away from operator interference, but the available installation space is limited due to existing equipment like air conditioners
Solution Approach 1:
The bracket is designed with flange portions that fit through the base plate's through hole, with side portions passing through the same hole, and the bottom portion coupling to secure the controller. This nested structure allows the controller assembly to be installed in the limited space behind the operator's seat by utilizing the existing base plate opening, effectively nesting the controller within the available cabin space.
Solution Approach 2:
The bracket extends in multiple dimensions - the flange portions are supported on the upper surface of the frame, the side portions pass through the through hole in the vertical direction, and the bottom portion couples on the lower surface side. This multi-dimensional arrangement allows the controller to be positioned in the limited space behind the operator's seat while maintaining proper connections and orientation.
2Ease of operation
If additional equipment is installed in the limited space behind the operator's seat, then the controller can be positioned for optimal connection and protection, but the assembly process becomes difficult and time-consuming
Solution Approach 1:
The bracket is pre-assembled with the controller main body mounted on its bottom portion before installation into the cab. The flange portions are positioned on the base plate's upper surface, and the side portions are ready to pass through the through hole. This preliminary assembly simplifies the final installation process, as the entire controller assembly can be installed as one unit through the existing opening, reducing installation complexity and time.
Solution Approach 2:
The bracket is divided into distinct functional segments: flange portions for support on the base plate, side portions for passing through the through hole, and a bottom portion for mounting the controller. This segmentation allows each part to perform its specific function efficiently and simplifies the overall assembly and installation process.
3Adaptability or versatility
If the controller is installed in the limited space behind the operator's seat, then it can be integrated into the cab, but the vibration from the engine and work implement may affect the controller's operation
Solution Approach 1:
The bracket serves as an intermediary structure between the base plate (cab structure) and the controller main body. It is mounted to the base plate through the flange portions supported on the upper surface and secured through the side portions passing through the through hole, while providing a stable mounting platform for the controller on its bottom portion, isolating the controller from direct vibration transmission.
4Ease of manufacture
If the bracket structure is designed to allow easy assembly through the base plate, then installation is simplified, but the structural strength must be maintained to support the controller securely
Solution Approach 1:
The bracket combines multiple structural elements into one integrated component: the flange portions that support the controller on the base plate's upper surface, the side portions that pass through the through hole for securement, and the bottom portion that mounts the controller. This merged structure provides both easy assembly through the existing opening and sufficient structural strength to securely support the controller in the vibration-prone environment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates easy and efficient assembly of the controller assembly, effectively utilizing limited space and protecting the controller main body from vibrations, allowing for seamless integration into the work machine's cab.
Implementation Method 1
a vibration damping member arranged between the controller main body and the bracket is further provided. Therefore, vibrations transmitted from the bracket to the controller main body can be suppressed by the vibration damping member

AI summary
A controller assembly includes a base plate, a bracket, and a first controller main body. The base plate includes a through hole and a frame having an upper surface and a lower surface and surrounding the through hole. The bracket has first and second flange portions supported on the upper surface of the frame at positions opposite to each other over the through hole, first and second side portions coupled respectively to the first and second flange portions and passing through the though hole; and a bottom portion coupled to both of the first and second side portions on the side of the lower surface of the frame. The first controller main body is mounted on a bottom portion of the bracket. Accordingly, a controller assembly which can be readily assembled, a cab of a work implement, and a work machine can be obtained.
