Shredder Shock Absorbing Element Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Shredders experience vibrations, noise, and rocking during operation, which are undesirable, and existing solutions like springs between the shredder mechanism and housing do not adequately address these issues, especially when the bin is near capacity.
Innovation Solution
Incorporating a shock absorbing element with a resilient section connecting the shredder mechanism and housing, featuring offset legs and a clearance between them to reduce vibration transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If springs are provided adjacent to the connection point between the shredder mechanism and housing to reduce vibrations, then vibration reduction is improved, but the device complexity increases and noise reduction is insufficient
Solution Approach 1:
The shock absorbing element is divided into three distinct functional segments: a first leg connected to the shredder mechanism, a second leg connected to the housing, and a resilient section interconnecting them. This segmentation allows each part to perform its specific function - the legs provide structural connection while the resilient section specifically handles vibration absorption, resolving the contradiction by organizing complexity into functional modules.
Solution Approach 2:
The resilient section acts as an intermediary element between the shredder mechanism and the housing. Instead of directly connecting the mechanism to the housing with rigid springs, the resilient section mediates the connection, absorbing vibrations and shocks while allowing the connection to remain relatively simple. This intermediary approach reduces vibration transmission without significantly increasing overall device complexity.
2Object-affected harmful factors
If traditional spring mounting is used to reduce vibrations, then some vibration reduction is achieved, but noise reduction and rocking prevention are insufficient
Solution Approach 1:
The resilient section is designed to provide beforehand cushioning by absorbing shocks and vibrations before they can propagate through the housing and cause noise or rocking. The resilient material is selected and dimensioned to cushion the impacts that occur during normal operation, preventing these disturbances from reaching levels that would cause excessive noise or instability.
Solution Approach 2:
The resilient section utilizes flexible material properties to absorb vibrations and dampen shocks. This flexible element can deform under impact loads and then return to its original shape, providing continuous cushioning during operation. The flexibility allows it to absorb a broader range of vibration frequencies compared to rigid springs, thereby reducing noise and preventing rocking more effectively.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The shock absorbing element effectively reduces vibrations and noise, enhancing the stability and operational quietness of the shredder, even when the bin is full.
Implementation Method 1
a resilient section interconnecting the first and second legs in a spaced apart relation. The at least one shock absorbing element is configured to at least reduce vibrations transmitted from the shredder mechanism to the shredder housing during operation of the shredder.

AI summary
Disclosed herein is a shredder with a shredder housing and a shredder mechanism received in the housing, the shredder mechanism enabling the at least one article to be shredded to be fed into cutter elements and a motor being operable to drive the cutter elements in a shredding direction. The shredder also includes at least one shock absorbing element configured to connect the shredder mechanism and shredder housing. The shock absorbing element has a first leg connected to the shredder mechanism, a second leg connected to the shredder housing, and a resilient section interconnecting the first and second legs in a spaced apart relation, so that the shock absorbing element may at least reduce vibrations transmitted from the shredder mechanism to the shredder housing during operation of the shredder.
