Elastic Pill Bottle Insert for Headspace Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pill bottle containers experience rattling noise and premature degradation of tablets or capsules due to headspace, which is not effectively addressed by traditional methods like using cotton balls, as they can cause moisture issues and are not adaptable to changing volume.
Innovation Solution
A lightweight, pliable, and elastic pill container insert that occupies the headspace, expands and shrinks to restrict movement, featuring a ring pull or lanyard for easy removal, and can be integrated with the pill bottle cap or contain a plunger for sealing, made from moisture-resistant materials like cellular foam or polymers, optionally with sensors for quality monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If cotton balls are used to occupy headspace, then rattling noise is reduced, but moisture control deteriorates and usability worsens
Solution Approach 1:
The patent changes the physical state and material properties of the headspace occupying element from traditional cotton balls to a compressible foam material that can be compressed to a thin profile for insertion and then expands to fill the headspace volume, providing both noise reduction and moisture control capabilities
Solution Approach 2:
The patent uses a composite structure combining a compressible foam core with an outer shell or coating that provides moisture barrier properties, creating a multi-functional element that addresses both noise and moisture control simultaneously
2Object-generated harmful factors
If cotton balls are used to occupy headspace, then rattling noise is reduced, but ease of operation deteriorates
Solution Approach 1:
The patent makes the headspace occupying element dynamically adjustable by providing a compressible structure that can be compressed to a compact form for easy insertion and removal, while automatically expanding to fill the headspace when in use, enabling users to access medication without difficulty
Solution Approach 2:
The patent incorporates a removable cap or lid portion on the headspace occupying element that can be separated to allow access to the medication while maintaining the noise-reducing and moisture-control functions when closed
3Loss of information
If standard sized bottles are used for labeling requirements, then product information is displayed, but headspace increases causing rattling and degradation
Solution Approach 1:
The patent extracts the headspace problem by introducing a removable headspace occupying element that can be inserted into the bottle to fill the empty volume, allowing the use of standard bottle sizes for labeling requirements while eliminating the harmful effects of headspace through the addition of this separate component
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 insert effectively silences rattling noise, prevents degradation, and maintains product quality by securely holding pills in place while allowing for easy access and sealing, with the ability to monitor and indicate moisture or quality issues.
Implementation Method 1
A lightweight, pliable, and elastic pill container insert that occupies the headspace, expands and shrinks to restrict movement
Implementation Method 2
the insert can be compressed to a smaller shape or configuration relative to its un-compressed shape or configuration, and inserting the compressed insert into a pill container
Data Source
AI summary
A lightweight pill container headspace occupying insert apparatus is disclosed that can be configured to conform to the general shape of an inner region of a pill container, such that the insert occupies or fills in the open or headspace the pill container thereby preventing movement of one or more pills or tablets within the container, among other advantages. The insert can include a biasing member having a first end and a second end, a first disc secured to the first end of the biasing member and a second disc secured to the second end of the distal member, wherein the first disc and second disc are configured to substantially align with an interior space of a pill container.
