Folded Lubricant Sheet for Controlled Shredder Blade Oiling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lubrication systems for shredders often result in uneven distribution and wasteful dispersion of lubricant, leading to inefficient lubrication of cutter elements and potential damage to the shredder mechanism.
Innovation Solution
A lubricant sheet with a folded configuration that includes a primary barrier and secondary barriers to contain and deflect lubricant, forming a manifold for controlled release and redistribution, ensuring consistent lubrication of cutter elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealed lubrication package is used to contain lubricant, then lubricant retention is improved, but compression pressure builds up during shredding causing uneven distribution
Solution Approach 1:
The sealed lubrication package is segmented into multiple compartments separated by partitions. This segmentation allows the lubricant to be distributed in controlled portions as the package is shredded, preventing excessive compression pressure buildup while maintaining effective lubricant containment and distribution to the cutter elements.
2Stress or pressure
If lubricant is released through vent holes during shredding, then compression pressure is relieved, but lubricant distribution becomes uneven and wasteful
Solution Approach 1:
The lubrication package incorporates multiple lubricant-containing compartments positioned at different locations within the package structure. Each compartment is strategically positioned to ensure uniform lubricant distribution across various cutter elements as the package is shredded, preventing both pressure buildup and uneven lubricant application.
3Ease of operation
If manual oiling is performed to lubricate cutter elements, then lubrication can be applied directly, but the process is time-consuming and inconsistent
Solution Approach 1:
The lubrication package is designed to be self-lubricating during the shredding process. As the package is fed into the cutter elements, the lubricant is automatically released and distributed to the cutter surfaces through the segmented compartment structure, eliminating the need for separate manual oiling operations and ensuring consistent lubrication without additional time investment.
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
The lubricant sheet effectively extends the lifespan of shredder components by maintaining lubrication and reducing wear on cutter elements, while minimizing waste and improving operational efficiency.
Implementation Method 1
a primary barrier for the lubricant extending around and sealing the lubricant containment pocket so as to hold the lubricant in the lubricant containment pocket
Implementation Method 2
the secondary barrier is configured to deflect the released lubricant that is released towards the secondary barrier so as to relieve pressure in the released lubricant and to maintain the released lubricant in place for further lubrication
Implementation Method 3
wear on cutter elements/blades of the shredder mechanism and load on the shredder motor may be reduced by oiling the cutter elements of the shredder mechanism

AI summary
A lubricant sheet comprises a blank of material folded along a fold line into a folded configuration to form a lubricant containment pocket; a lubricant in the lubricant containment pocket; and a primary barrier for the lubricant. The primary barrier extends around and seals the lubricant containment pocket to hold the lubricant in the lubricant containment pocket. The blank of material includes a fold of material along the fold line forming a secondary barrier for the lubricant. When the lubricant in the lubricant containment pocket is being compressed during shredding of the lubricant sheet so as to cause some of the lubricant to be released through the primary barrier, the secondary barrier is configured to deflect the released lubricant that is released towards the secondary barrier.
