Nestable Bottle Sliding Lid Mechanism for Arthritis Users
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Many individuals, particularly the elderly with physical limitations such as arthritis or diminished strength, face difficulties in unscrewing or snapping off bottle caps, which is a critical issue for accessing daily medicines.
Innovation Solution
A nestable bottle design where a first cylindrical portion slides into a second cylindrical portion, secured by frictional forces instead of screw threads or snapping fixtures, allowing easy access and removal of the lid without exertion, featuring a sealant to prevent air and moisture ingress and grip aids for user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw-on or snap-on caps are used to secure the bottle lid, then the seal and closure reliability are improved, but the ease of operation deteriorates for individuals with physical limitations
Solution Approach 1:
The bottle is divided into two separate portions: a first portion containing the lid and a second portion containing the bottle body. The lid portion can be easily separated from the bottle body through a simple sliding motion, eliminating the need for unscrewing or snapping actions that require significant force.
Solution Approach 2:
The first bottle portion (lid) is designed to nest within or slide over the second bottle portion (body). This nested configuration allows the lid to be securely positioned while enabling easy removal through a simple sliding motion, combining security with ease of operation.
2Object-affected harmful factors
If a secure lid mechanism is implemented to prevent contamination, then the protection against air and moisture ingress is improved, but the device complexity increases
Solution Approach 1:
The complex threading and snapping mechanisms are extracted and replaced with a simple sliding interface. The seal function is maintained through direct contact between the first and second bottle portions, eliminating unnecessary mechanical complexity while preserving protection against contamination.
Solution Approach 2:
The seal between the first and second bottle portions is achieved through flexible sealing surfaces that conform to each other during the sliding motion. This flexible sealing approach provides effective protection against air and moisture ingress without requiring complex rigid sealing mechanisms.
3Ease of operation
If the bottle lid is designed to slide into the bottle body, then the ease of operation is improved, but the sealing effectiveness may deteriorate
Solution Approach 1:
The sliding interface is designed with localized sealing features at specific contact points between the first and second bottle portions. These localized sealing zones concentrate the sealing function at critical areas, ensuring effective sealing while maintaining the simplicity of the sliding motion for easy operation.

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 nestable bottle design simplifies the process of accessing and replacing the lid, making it easier for individuals with physical limitations to use medicinal bottles, improving accessibility and usability for millions of people.
Implementation Method 1
the bottle first portion may include at least one frictional engagement feature formed on an outer surface of the lid on the bottle first portion
Implementation Method 2
the nestable bottle may include at least one sealant feature to seal out air and/or moisture
