Glass Bottle Impact Protection with Segmented Damping Studs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shock protection devices for glass bottles, particularly those containing pharmaceutical products, are inadequate in absorbing impact energy, often leading to breakage and hinder visual inspection of contents, and are not environmentally friendly.
Innovation Solution
A shock protection device comprising two cups, each with a discontinuous circumference and elastomeric studs that allow relative movement during impact, providing enhanced energy absorption and visibility, while being recyclable or biodegradable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a continuous shock absorber travels the circumference of the bottle, then shock protection is provided, but energy absorption is limited due to restricted deformation freedom
Solution Approach 1:
The continuous shock absorber is divided into multiple discrete studs arranged around the circumference of the bottle. Each stud can deform independently, providing greater freedom of movement and energy absorption capability compared to a continuous rigid structure. The studs are spaced apart to allow individual deformation while collectively providing circumferential protection.
2Reliability
If plastic boxes surround the bottle for protection, then shock absorption is provided, but visual inspection of contents is hindered and the device is expensive
Solution Approach 1:
Instead of completely surrounding the bottle with opaque protective material, the invention uses discrete studs that provide shock absorption only at specific contact points around the circumference. This localized approach allows the majority of the bottle surface to remain visible and accessible for inspection, while still providing effective protection at critical impact zones.
3Strength
If thermosetting material is used to shrink around the container, then intimate cooperation between cover elements is achieved, but heat-sensitive medicines are damaged and shock absorption is insufficient
Solution Approach 1:
The invention replaces expensive, heat-sensitive thermosetting materials with simpler, heat-resistant stud elements that can be attached using heat-resistant adhesives or mechanical means. These studs provide sufficient shock absorption for their intended use lifecycle without requiring the complex shrink-fitting process of thermosetting materials, and they can be easily replaced if needed.
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 device significantly reduces bottle breakage during falls and allows visual inspection of contents, offering improved ergonomics and environmental sustainability.
Implementation Method 1
the deformation of the studs, preferably elastic, is greater than in the case of a shock absorber continuously traveling the circumference of the bottle so that more energy can be absorbed
