Plastic Container Resilient Running Ring Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plastic containers for transporting goods are prone to noise and vibration when moved on roller conveyors, especially when carrying sensitive equipment, due to the abrupt contact with rollers, which can lead to increased noise and potential deformation.
Innovation Solution
A plastic container design featuring a resilient running ring with a recess and groove on its outer edge, where the recess is open to the outside and has a bottom side that is more resilient than the top side, and a groove that can be V-shaped or have a decreasing thickness, allowing for gentle cushioning and reduced noise, and sloping ribs that prevent deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the container base has a rigid running ring for stable transport, then stability is improved, but noise and vibration increase when rolling on conveyors
Solution Approach 1:
The running ring incorporates a resilient bottom side that acts as a flexible element, allowing the rigid-looking structure to deform elastically during roller contact, thereby absorbing impact energy and reducing noise transmission
Solution Approach 2:
The resilient bottom side is pre-configured to provide cushioning effect before the actual roller contact occurs, preparing the structure to absorb upcoming impacts and minimize noise generation during the rolling process
2Strength
If the container base has a rigid running ring for structural strength, then strength is improved, but vibration increases when transported on roller conveyors
Solution Approach 1:
The resilient bottom side functions as a vibration-dampening flexible layer that absorbs shock waves and reduces vibration transmission to the container contents while preserving overall structural strength
Solution Approach 2:
The pre-configured resilient structure provides advance cushioning against roller contact, preventing vibration generation before it can propagate through the container structure
3Ease of manufacture
If the running ring has uniform thickness for manufacturing simplicity, then ease of manufacture is improved, but noise reduction capability decreases
Solution Approach 1:
The running ring features non-uniform thickness with a specifically thinned resilient bottom side in the roller contact area, while other areas maintain sufficient thickness for structural integrity, optimizing noise reduction locally without compromising overall strength
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 design minimizes noise and vibration when rolling over rollers, allowing for the transport of sensitive goods by providing a gentle rolling process and increased stability, reducing the risk of noise and deformation.
Implementation Method 1
the bottom side being resilient compared to the top side
Implementation Method 2
the rolling-up process is gently cushioned when the running ring is rolled up onto a transport roller
