Vacuum Container Date Display Dialing Rings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum container systems lack an efficient and reliable date display system for indicating the storage start or expiration date, which is crucial for food preservation.
Innovation Solution
A vacuum container with a lid equipped with a valve for air extraction, made from materials suitable for various temperatures, and a date display system comprising two independently rotating dialing rings with date indication openings, allowing manual setting of the date, which can be done before, during, or after the vacuum generation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a date display system is added to the vacuum container, then the ability to track storage dates is improved, but the device complexity increases
Solution Approach 1:
The patent replaces complex electronic date display systems with a simple mechanical dialing ring system. The dialing rings with date markings can be manually rotated to set and display dates, eliminating the need for batteries, circuits, or digital displays while achieving the same date tracking function.
Solution Approach 2:
The patent uses simple, inexpensive mechanical components (dialing rings with printed date markings) instead of expensive electronic date display systems. These mechanical components are durable yet simple enough to be replaced if needed, providing cost-effective date tracking.
2Ease of operation
If manual date setting is enabled, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent replaces complex electronic interfaces for date setting with simple mechanical dialing rings that can be manually rotated. Users can easily set dates by turning the rings to align desired date markings with a reference point, providing intuitive operation without electronic complexity.
Solution Approach 2:
The dialing rings are designed to be directly manipulated by users without requiring buttons, switches, or electronic interfaces. The mechanical system allows users to set and adjust dates themselves through simple rotation, making the device self-operating for date setting functions.
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
Enables easy and intuitive manual setting of specific dates for storage or expiration, ensuring accurate tracking and extending the shelf life of food while maintaining a clean and dry environment.
Implementation Method 1
The vacuum storage box technology is based on the vacuum production process inside the container performed by sucking air out of the container to create a vacuum inside the container
