Lockable Moisture-Proof Pill Box with Elastic Sealing and Pushing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pill boxes are prone to moisture ingress due to inadequate sealing, causing pill spoilage, and the lids are easily damaged and difficult to open fully, making it inconvenient to retrieve medication.
Innovation Solution
A lockable and moisture-proof pill box design featuring a storing base with compartments, pivotally mounted lids, and an elastic sealing and pushing member that includes a sealing ring and pushing bar, ensuring airtight sealing and automatic lid opening for easy access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealing structure is added between the container and lid to prevent moisture ingress, then moisture protection is improved, but device complexity increases
Solution Approach 1:
The patent employs a flexible sealing ring made of elastic material that deforms to create a moisture-proof seal between the lid and container. The sealing ring is mounted in a groove and elastically contacts the lid surface, forming an effective barrier against moisture ingress without requiring complex sealing mechanisms
Solution Approach 2:
The patent extracts the sealing function from the rigid lid structure and implements it through a separate, dedicated sealing ring component. This modular approach allows the sealing function to be independently optimized while keeping the main lid structure simple and rigid
2Strength
If the lid is made of rigid plastic material for durability, then strength is improved, but ease of operation deteriorates due to deformation at closed position
Solution Approach 1:
The patent introduces a pushing member as an intermediary element between the sealing ring and the lid. When the sealing ring is compressed during closing, it activates the pushing member which then exerts force on the lid to push it open. This mediator converts the sealing action into an automatic opening mechanism, resolving the conflict between rigid lid durability and ease of operation
3Reliability
If the lid is slightly deformed and bent at closed position to engage with container, then locking reliability is improved, but lid damage increases due to repeated deformation
Solution Approach 1:
The patent extracts the deformation function from the lid itself and transfers it to the sealing ring. The sealing ring is designed to be elastically deformable and absorbs all the deformation stress during closing and opening operations. The rigid lid never deforms, eliminating fatigue damage while maintaining reliable locking through the sealing ring's engagement

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 pill box effectively prevents moisture ingress, maintains pill integrity, and allows easy retrieval of medication while simplifying assembly and reducing lid damage.
Implementation Method 1
The at least one sealing and pushing member (30) is elastic. Each of the at least one sealing and pushing member (30) has a sealing ring (31) and a pushing bar (32)

AI summary
A lockable and moisture-proof pill box has a storing base having at least one compartment for holding pills, at least one lid pivotally mounted on the storing base, and at least one sealing and pushing member. Each of the at least one lid has a sealing ring and a pushing bar integrally formed as a single part. With the at least one sealing and pushing member mounted between the storing base and the at least one lid, the at least one compartment in the storing base can be airtightly sealed by the sealing ring when being closed, so as to prevent the pills in the at least one compartment from being spilt. Moreover, each of the at least one lid can be automatically opened by push of the pushing bar. Thus, a user can take the pills held in the compartment easily and conveniently.
