Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disintegrating devices suffer from high downtime due to sieve elements blocking or deforming when processing oversized materials, which leads to damage and reduced operational efficiency.
Innovation Solution
A disintegrating device with a spring-mounted sieve element that can recede and move in multiple directions to avoid oversized material, combined with a cardanic suspension and adjustable spring system, allowing for flexible installation and maintenance, and a swiveling mechanism to adjust the distance and orientation of the sieve elements relative to the disintegrating roller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If sieve elements are fixed rigidly on the base comb, then structural stability is improved, but the sieve elements block or deform when encountering oversized material, causing damage and high downtime
Solution Approach 1:
The patent applies the dynamics principle by making the sieve elements movable rather than fixed. Each sieve element is mounted on a swiveling suspension that allows it to move independently. When oversized material encounters a sieve element, the suspension enables the element to swivel away from the material flow, preventing blocking and damage while maintaining structural integrity during normal operation.
2Reliability
If sieve elements are made movable to avoid oversized material, then operational reliability is improved, but device complexity increases due to suspension mechanisms
Solution Approach 1:
The patent applies segmentation by dividing the sieve structure into multiple independent sieve elements, each with its own suspension mechanism. This allows individual elements to move independently without affecting the entire sieve structure. The modular design reduces overall complexity compared to a single large movable sieve, as each element is a simple, self-contained unit.
Solution Approach 2:
The patent uses the suspension mechanism as an intermediary between the fixed base comb and the movable sieve elements. This intermediary component absorbs the complexity of the movement mechanism while maintaining a simple interface with both the structure and the sieve elements, reducing the perceived complexity of the overall system.
3Productivity
If the sieve device encircles the disintegrating roller completely, then processing efficiency is improved, but the risk of damage from oversized material increases
Solution Approach 1:
The patent maintains the encircling sieve device configuration for optimal processing efficiency, but applies dynamic movement capability to each sieve element through the suspension system. This allows the sieve elements to actively respond to oversized material by moving away, preventing damage while maintaining the beneficial encircling configuration for continuous processing.
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
This design significantly reduces downtime and increases the device's operational efficiency by preventing sieve element damage and allowing for adaptable processing of various material sizes, while enabling easy maintenance and adjustment.
Implementation Method 1
the sieve element is spring-mounted on the base comb
Implementation Method 2
The springy support allows that during the disintegrating process the sieve elements are able to recede as they can move back because of the springy support when over-sized material enters
Implementation Method 3
a cardanic suspension is particularly suited for the above-described dodging movements in two different directions
