Sealed storage box with latching closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sealed storage boxes lack an efficient mechanism for sealing and opening, which compromises their effectiveness in maintaining freshness and security for stored food and materials.
Innovation Solution
A sealed storage box design featuring a container with a lid that includes a bottom plate with a horizontally projected arm, a top plate with connectors, a top plate anchor, and a movable latch, along with a circular seal that tightens when the lid is closed, allowing for easy opening and sealing through the movement of the latch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional sealing mechanism is used, then the structure is simple, but the sealing effectiveness and security are compromised
Solution Approach 1:
The closure mechanism employs movable latch members that can transition between engaged and disengaged states, providing dynamic sealing control. The latch members move along curved paths defined by cam surfaces, enabling reliable sealing when closed while allowing easy opening when needed.
Solution Approach 2:
The closure system is divided into multiple independent latch members (first latch member, second latch member) that can operate separately. Each latch member engages with corresponding engagement surfaces on the container and lid, distributing the sealing function across multiple segments for enhanced reliability.
2Reliability
If a secure sealing mechanism is implemented, then contamination and spoilage are prevented, but the ease of opening is reduced
Solution Approach 1:
The latch members are designed to move dynamically between locked and unlocked positions. When closed, the cam surfaces guide the latches into secure engagement with the container and lid. When opening is needed, the latches can be easily disengaged by applying force to move them along their defined paths, providing both security and ease of operation.
Solution Approach 2:
The cam surfaces act as intermediary elements that translate simple user input (pushing the latch) into the complex motion required for secure engagement or easy disengagement. The curved cam paths provide mechanical advantage, making it easy to open while maintaining secure closure.
3Reliability
If multiple latch members are used, then the seal reliability is improved, but the device complexity increases
Solution Approach 1:
The closure system uses multiple independent latch members (first and second latch members) that can be manufactured as separate components. Each latch member has its own engagement surfaces and movement path, allowing for modular manufacturing and assembly while providing redundant sealing points for enhanced reliability.
Solution Approach 2:
Both latch members perform the same fundamental function of securing the lid to the container, but they are positioned at different locations to provide distributed sealing. This multi-functionality approach maintains reliability without requiring each individual latch to be overly complex.

AI summary
A storage box that includes a container and a lid, which includes a bottom plate, a top plate, a top plate anchor and a movable latch. The bottom plate includes an arm that the height of its left section is bigger than the height of its right section, and its inclined middle section inclines from left to right. The movable latch includes a protrusion that its left section is flat and the inclined right section inclines and descends from left to right. The movable latch is designed to be positioned between the top plate and the bottom plate, in a way that the horizontal protrusion is inserted under the horizontal arm of the bottom plate and the movable latch can be moved from right to left and back.
