Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing buckets for screening and crushing inert materials require two separate motor units, leading to inefficient energy use and impractical operation, as they perform screening and crushing in sequential stages without coordination.
Innovation Solution
A bucket with integrated screening and crushing capabilities, utilizing a three-way hydraulic valve and detecting device to selectively operate screening and crushing units based on the bucket's orientation, allowing for coordinated and energy-efficient operation with a single hydraulic fluid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two separate motor units are used for screening and crushing operations, then both functions can be performed, but energy consumption increases and operational complexity increases
Solution Approach 1:
The patent combines two separate motor units into a single motor unit that drives both the screening device and crushing mechanism through a shared hydraulic system. The three-way hydraulic valve distributes hydraulic fluid flow to either the screening device or crushing mechanism as needed, eliminating the need for two independent motor units and reducing energy consumption while maintaining both functional capabilities.
Solution Approach 2:
The single motor unit with three-way hydraulic valve serves multiple functions by being able to drive both the screening device and crushing mechanism. This universal system can selectively perform screening, crushing, or both operations by directing hydraulic fluid flow appropriately, replacing the need for dedicated motor units for each function.
2Adaptability or versatility
If two separate motor units are used for screening and crushing operations, then both functions can be performed, but device complexity increases
Solution Approach 1:
The patent merges two separate motor units into one integrated motor unit with a three-way hydraulic valve. This consolidation reduces the number of independent components from two to one, simplifying the overall device structure while preserving the ability to perform both screening and crushing functions through selective hydraulic fluid distribution.
3Productivity
If screening and crushing are performed in sequential stages without coordination, then both operations can be completed, but operational efficiency decreases
Solution Approach 1:
The patent implements dynamic coordination between screening and crushing operations through the three-way hydraulic valve, which can real-time control the distribution of hydraulic fluid flow. This allows the system to adaptively switch between screening, crushing, or combined operations based on material characteristics and processing requirements, optimizing energy efficiency while maintaining productivity.
Solution Approach 2:
The coordinated system allows for continuous useful action by enabling overlapping screening and crushing operations. Instead of strict sequential execution with idle transitions, the hydraulic valve can maintain continuous material flow through the system, with screening and crushing occurring in an integrated manner that eliminates wasted time and energy during stage transitions.
4Adaptability or versatility
If two separate motor units are used, then screening and crushing can be performed, but operator control complexity increases
Solution Approach 1:
The patent merges the control of two separate motor units into a single control interface for the three-way hydraulic valve. The operator now controls one integrated system that can selectively perform screening, crushing, or both functions, rather than managing two independent motor units with separate controls, significantly simplifying the operating interface and reducing control complexity.
