Medication Storage Cell with Segmented Adhesive Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medication storage packaging bodies are difficult for individuals with dexterity issues to open, as they require significant finger strength or dexterity to access the medication.
Innovation Solution
A medication storage cell design featuring overlapping sheets that can be easily opened by reducing adhesive strength and incorporating a sheet restraining section, allowing for easy release of the outlet, even by those with limited dexterity, along with a friction coefficient difference between inner and outer surfaces for easier removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the outlet is formed by overlapping sheets with strong adhesive strength to maintain secure sealing, then the reliability of sealing is improved, but the ease of operation deteriorates because persons with limited dexterity cannot easily open the packaging
Solution Approach 1:
The overlapping sheets are divided into multiple sections: a restrained section that maintains strong adhesion for secure sealing, and an unrestrained section that allows easy peeling for opening. This segmentation enables different regions to serve different functions - the restrained section ensures reliability while the unrestrained section provides ease of operation.
Solution Approach 2:
Different adhesive properties are applied to different locations of the overlapping sheets. The restrained section has high adhesive strength to maintain sealing reliability, while the unrestrained section has low adhesive strength to enable easy opening by persons with limited dexterity. This local differentiation resolves the contradiction between secure sealing and easy opening.
2Reliability
If the overlapping sheets are completely restrained to prevent opening, then the reliability of maintaining closed state is improved, but the ease of operation deteriorates because the outlet cannot be opened even by persons with limited dexterity
Solution Approach 1:
The overlapping sheets are segmented into restrained and unrestrained sections. The restrained section maintains strong adhesion to prevent premature opening and ensure reliability, while the unrestrained section is designed to be easily peeled even by persons with limited dexterity, thus resolving the contradiction.
Solution Approach 2:
The unrestrained section acts as an intermediary mechanism between the restrained section and the user. It provides a controlled weakness point that allows easy initiation of opening while the restrained section maintains overall sealing integrity, enabling both reliability and ease of operation.
3Ease of operation
If the adhesive strength between overlapping sheets is reduced to enable easy opening, then the ease of operation is improved, but the reliability of sealing deteriorates
Solution Approach 1:
Different adhesive strengths are applied locally to different sections of the overlapping sheets. The unrestrained section has reduced adhesive strength for easy opening, while the restrained section maintains high adhesive strength for reliable sealing, thus resolving the contradiction between ease of opening and sealing reliability.
Solution Approach 2:
The overlapping sheets are segmented into regions with different adhesive properties. The unrestrained section provides easy opening capability while the restrained section ensures sealing reliability, allowing the package to meet both requirements simultaneously.

AI summary
[Problem] To provide a medication storage cell that can be easily opened by a person who cannot dexterously move his or her fingertips. [Solution] A small-medication storage cell 12 is provided with an accommodating section 20 and an interlocking piece 22. The accommodating section 20 has an outlet for a medication 100. The outlet 30 is formed using a sheet 60 provided with an interlocking piece, and a cover sheet 62. The interlocking piece 22 has a base section 40 and a tip end section 42. At least a part of the base section 40 is separated from the surface of the accommodating section 20. The tip end section 42 is fastened to the accommodating section 20 in a bent state so that the cover sheet 62 and the sheet 60 provided with an interlocking piece close the outlet 30.
