Single-Motor Linkage for Waste Bin Lifting and Compacting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solid waste collection and compaction systems are complex, heavy, and costly due to the need for multiple subsystems and motors to perform lifting, tipping, compacting, and dumping operations.
Innovation Solution
A system with a single motor-driven linkage assembly that lifts, tips, and compacts bins, using a packer plate pivotally connected to the container body, and a container assembly that pivots between rest and dump positions, reducing the number of parts and improving stability by lowering the center of mass.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple subsystems and motors are used to perform lifting, tipping, compacting, and dumping operations, then the system can perform all required functions, but the device complexity, weight, and cost increase
Solution Approach 1:
A single motor is designed to perform multiple functions including lifting the bin, tipping the bin for emptying, compacting the solid waste materials, and pivoting the container body. This multi-functional approach eliminates the need for separate motors for each operation, thereby reducing device complexity while maintaining all required functional capabilities
Solution Approach 2:
The patent combines multiple subsystems (lifting mechanism, tipping mechanism, compacting mechanism, and pivoting mechanism) into a single integrated system driven by one motor. The linkage assembly merges these functions into a coordinated operation, reducing the number of independent components and simplifying the overall system architecture
2Ease of operation
If multiple motors are used for different operations, then each operation can be performed independently, but the weight and cost of the system increase
Solution Approach 1:
The single motor is designed with sufficient power and torque to perform all operations independently when needed. The control system enables the motor to switch between different functions (lifting, tipping, compacting, pivoting) as required, maintaining operational independence while using only one motor instead of multiple
3Device complexity
If a single motor is used for all operations, then the system weight and complexity are reduced, but the motor must be more powerful and the linkage assembly more complex
Solution Approach 1:
The linkage assembly is designed as a dynamic mechanical system that transforms the rotational motion of the single motor into the required linear and angular motions for different operations. Mechanical advantage is achieved through linkages, levers, and pivots that amplify the motor's force output as needed for each specific operation
Solution Approach 2:
The linkage assembly acts as an intermediary mechanism between the single motor and the various operational components. It translates the motor's rotational force into the appropriate form and magnitude of force required for lifting, tipping, compacting, and pivoting operations

AI summary
A system for lifting and tipping a bin containing solid waste materials in a container body and for compacting the solid waste materials in the container body includes a motor, a packer plate, and at least one linkage assembly operatively connected to the motor. When the motor is operated, the at least one linkage assembly is configured for lifting the bin above the container body, tipping the bin, pivoting the packer plate from a retracted position to a compacting position and then from the compacting position to the retracted position, and lowering the bin back down. A solid waste materials collection and compaction container assembly has a container body and a system for lifting and tipping a bin in the container body, and for compacting solid waste materials in the container body.
