Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional counterweights for construction vehicles are challenging to install and maintain, often causing uneven weight distribution and shifting of the center of gravity, which affects the vehicle's stability, reliability, and component wear.
Innovation Solution
A construction vehicle design featuring a linkage assembly with a conduit system and removably positioned weight members within a cavity defined by the conduit, allowing for easy adjustment and placement of counterweights near the material engaging portion to maintain balance and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional counterweights are added to the construction vehicle, then the weight and balance are improved, but the installation complexity and time increase
Solution Approach 1:
The counterweight system is segmented into modular components: a base structure integrated with the work implement and removable weight portions that can be independently added or removed. This segmentation allows the counterweight function to be achieved without complex installation procedures, as the modular design simplifies both installation and adjustment processes.
Solution Approach 2:
The work implement structure itself serves dual purposes: it functions as both the working tool and the base for the counterweight system. The base structure is integrated into the work implement, eliminating the need for separate mounting structures and reducing installation complexity while maintaining the counterweight function.
2Stability of the object's composition
If conventional counterweights are added to the construction vehicle, then the weight and balance are improved, but the time and skill requirements for installation increase
Solution Approach 1:
The counterweight system is divided into a permanent base structure and removable weight portions. This segmentation enables quick installation by simply attaching the weight portions to the base, eliminating time-consuming welding or complex fastening operations required by conventional counterweight systems.
Solution Approach 2:
The base structure is pre-integrated with the work implement during manufacturing, with predetermined mounting features and alignment mechanisms. This preliminary preparation eliminates the need for complex on-site installation procedures, reducing both installation time and skill requirements while ensuring proper weight distribution.
3Stability of the object's composition
If conventional counterweights are added to the construction vehicle, then the weight distribution is adjusted, but the center of gravity shifts causing uneven weight distribution
Solution Approach 1:
The counterweight base structure is strategically positioned at the front of the work implement, close to the material engaging portion, to locally compensate for weight imbalances. This localized placement allows precise adjustment of the center of gravity without causing uneven weight distribution, as the counterweight can be fine-tuned to match specific operational requirements.
Solution Approach 2:
The counterweight system is designed to be dynamically adjustable, with removable weight portions that can be added or removed based on operational needs. This dynamic capability allows the center of gravity to be optimized for different working conditions, maintaining stability and preventing uneven weight distribution as the vehicle operates under varying loads.
4Stability of the object's composition
If conventional counterweights are added to the construction vehicle, then the balance is improved, but the probability of loosening and malfunction increases
Solution Approach 1:
The counterweight base structure is merged with the work implement as an integrated assembly, sharing common mounting points and structural support. This merging eliminates separate connections that could loosen, as the counterweight system becomes part of the work implement's primary structure, thereby improving reliability while maintaining balance.
Solution Approach 2:
The removable weight portions incorporate predetermined fastening features and alignment mechanisms that prevent loosening during operation. These pre-designed connection points include anti-loosening characteristics, cushioning against vibrations and dynamic loads, ensuring the counterweight remains securely in place while maintaining proper balance.
