Grid Shelf Rack Dampers for Quiet, Safer Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shelves with steel bars for self-service shops are noisy during assembly and pose a risk of injury due to ungrounded burrs, with the current noise reduction methods involving difficult and time-consuming spiral hose installations.
Innovation Solution
Incorporating dampers with a tapered receptacle design that enclose the end regions of lattice bars, providing a secure and noise-reducing attachment mechanism that minimizes the risk of injury and simplifies installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If spiral hoses are arranged at the contact points of the shelves to reduce noise, then noise level is reduced, but assembly time and complexity increase significantly
Solution Approach 1:
The damper is integrated directly into the lattice bar structure, merging the noise reduction function with the structural component itself. This eliminates the need for separate spiral hose attachments and reduces assembly steps while maintaining noise reduction effectiveness.
Solution Approach 2:
The damper is designed to be self-installing by simply placing the lattice bar end into the receptacle. The tapered shape provides self-alignment and the press-fit mechanism provides automatic securing without requiring additional tools or complex assembly procedures.
2Object-affected harmful factors
If spiral hoses are arranged at the contact points to reduce noise, then noise level is reduced, but device complexity increases
Solution Approach 1:
The damper is integrated directly into the lattice bar structure, merging the noise reduction function with the structural component itself. This eliminates the need for separate spiral hose attachments and reduces assembly steps while maintaining noise reduction effectiveness.
3Strength
If lattice bar ends are left exposed for structural purposes, then structural integrity is maintained, but risk of injury increases due to ungrounded burrs
Solution Approach 1:
The potentially harmful exposed ends with burrs are converted into a beneficial feature by enclosing them in dampers. The dampers protect users from injury while the tapered receptacle design maintains structural integrity through the clamping effect on the lattice bar ends.
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 solution effectively reduces noise during assembly, eliminates the risk of injury, and significantly reduces installation time and effort, offering substantial advantages over existing methods.
Implementation Method 1
The dampers 6 enclose the end regions 4a of each first lattice bar 4. The inner height hi of the damper 6 is adapted to the height h4 of the first lattice bar 4. The shape and size of the receptacle 7 with a circular boundary 10 is adapted to the shape and size of the second lattice bar 5. This achieves an additional clamping effect.
