Sealed can
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sealed cans require excessive force to open, often leading to spillage and accelerated aging of the sealing ring due to improper force application, causing inconvenience and reduced airtightness.
Innovation Solution
A sealed can design featuring a lid with a perforation, positioning blocking edge, flange, and a handle with a snap-fitted fixing member and handle mechanism that allows easy opening by pulling the handle without exerting force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sealing ring is forced into the container to achieve airtightness, then the sealing effect is improved, but the force required to open the lid increases
Solution Approach 1:
The sealing system is divided into a stationary sealing ring on the container and a movable sealing member on the lid. The sealing ring remains fixed to maintain airtightness, while the sealing member can be independently moved by the tab mechanism to break the seal without requiring excessive force.
Solution Approach 2:
The sealing member is designed to be movable relative to the lid, transitioning from a sealed position (contacting the sealing ring) to an unsealed position (retracted). This dynamic capability allows the seal to be broken easily by pulling the tab, reducing the force needed to open the lid while maintaining airtightness when closed.
2Ease of operation
If greater force is exerted to remove the lid, then the lid can be opened, but the sealing ring ages faster and airtightness deteriorates
Solution Approach 1:
The sealing function is extracted from the lid structure and placed on a separate, movable sealing member. This allows the sealing ring on the container to remain stationary and undamaged, while the sealing member on the lid carries the mechanical stress of opening/closing operations, protecting the sealing ring from aging.
Solution Approach 2:
The sealing member acts as an intermediary between the lid and the sealing ring. It absorbs the mechanical stress of opening operations through its movable design and tab mechanism, preventing direct force transmission to the sealing ring, thereby extending the sealing ring's service life while maintaining ease of opening.
3Ease of operation
If the lid is opened by improper force application, then the lid can be removed, but spillage occurs and user convenience is reduced
Solution Approach 1:
The sealing member is pre-positioned to contact the sealing ring when the lid is closed, ensuring airtightness. When the tab is pulled, the sealing member is preliminarily moved to break the seal before the lid is fully opened, preventing spillage during the opening process and improving user convenience.
