Multi-Joint Console Box Linkage for Horizontal Driver Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional console boxes for construction equipment, such as excavators, face issues with space utilization and safety due to their design, which can obstruct the driver's field of vision and movement, and require complex installations with large areas, especially when tilted or using slide moving devices.
Innovation Solution
A multi-joint driven console box with a forward and backward drive mechanism, featuring movable and fixed links connected by hinge pins, allowing the console box to move horizontally while maintaining a horizontal level, thus avoiding interference and simplifying installation in narrow spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the console box is tilted upwards by a given angle, then the console box can be positioned to avoid driver interference, but the space beside the driver's seat becomes narrow and obstructs the driver's field of vision and range of movements
Solution Approach 1:
The console box is designed to dynamically change its position between horizontal and tilted states based on operational requirements. It can be tilted upward to avoid driver interference during operation, then returned to horizontal position to restore driver's field of vision and movement space, making the system adaptive rather than static
Solution Approach 2:
The console box movement is extended from simple linear translation to multi-dimensional motion including horizontal movement along the Z-axis and angular tilting along the X-axis. This allows the console box to navigate around the driver's body in three-dimensional space, simultaneously achieving both driver clearance and preserved visibility
2Reliability
If the console box moves by means of the screw motor and the slide moving device having the moving screw, then the console box can be positioned, but the slide moving device with a relatively long length has to be installed on the underside of the console box, making the configuration complicated and requiring a large installation area
Solution Approach 1:
The positioning function is divided into two independent segments: horizontal positioning along the Z-axis and angular tilting along the X-axis. Each segment has its own dedicated drive mechanism (slide moving device for horizontal position, tilt drive mechanism for angular position), allowing compact integration and simplifying the overall configuration by separating functions that were previously combined in a single complex mechanism
Solution Approach 2:
The positioning mechanism utilizes three-dimensional space by implementing movement along the Z-axis (horizontal) and X-axis (tilting) independently. This spatial separation allows the drive mechanisms to be compactly arranged without requiring long slide moving devices, reducing both configuration complexity and installation area
