Solution Overview
Problem
Airtight boxes in the market face issues of inconvenience and noise due to the need for separate actions to open and lock, and the rolling mechanism requires space, reducing the effective volume.
Innovation Solution
An airtight box design that allows simultaneous opening by pulling out, featuring a sliding mechanism with a pushing member, connecting rod, and torsion spring for automatic opening and locking, and optional electrically driven structure for automatic operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rolling mechanism is used to release the locking device, then the locking function is achieved, but noise is generated and rolling space is required which reduces effective volume
Solution Approach 1:
The patent replaces the traditional rolling mechanism with a button-actuated mechanical system. The button (314) directly pushes the locking rod (321) to release the locking state, eliminating the need for rolling components and associated noise while maintaining reliable locking functionality.
Solution Approach 2:
The patent extracts and removes the rolling mechanism from the system entirely. By using a direct button-push action instead of rolling, the harmful rolling components that generate noise and occupy space are completely eliminated from the locking device structure.
2Reliability
If a rolling mechanism is used to release the locking device, then the locking function is achieved, but rolling space is required which reduces effective volume
Solution Approach 1:
The patent substitutes the space-consuming rolling mechanism with a compact button-actuated system. The button (314) and locking rod (321) arrangement requires minimal space compared to rolling components, thereby increasing the effective volume of the airtight box.
Solution Approach 2:
By removing the rolling mechanism entirely and replacing it with a direct-push button system, the patent eliminates the space required for rolling components, thus maximizing the effective volume available for storage.
3Reliability
If separate actions are used for opening and locking, then the locking function is achieved, but the operation process becomes inconvenient
Solution Approach 1:
The patent merges the opening and locking operations into a single integrated action. When the drawer body (1) is pulled outward, the pushing member (31) automatically pushes the locking rod (321) to release the locking state, enabling simultaneous opening and unlocking in one motion.
Solution Approach 2:
The pushing member (31) is pre-positioned to automatically actuate the locking rod (321) when the drawer is pulled. This preliminary arrangement ensures that the locking release action is automatically triggered by the opening motion itself, eliminating the need for separate manual locking operations.
4Reliability
If separate actions are used for opening and locking, then the locking function is achieved, but time is consumed for multiple operations
Solution Approach 1:
The patent combines multiple operations (opening and unlocking) into a single simultaneous action. As the drawer body is pulled outward, the locking mechanism is automatically released through the pushing member, eliminating the time required for separate locking operations.
Solution Approach 2:
The locking rod and pushing member are pre-configured to automatically interact during the opening motion. This preliminary arrangement ensures that the locking release occurs automatically and simultaneously with opening, minimizing the total time required for the operation.

AI summary
A sealed container (100), comprising a container body (1) and a cover body (2) covering the container body (1) to seal the container body (1). The container body (1) has an accommodation cavity (10) having an upward opening and two side walls (12) respectively positioned at two sides of the accommodation cavity (10). A slide groove (121) extending in a front-to-back direction is provided on the outer side of each side wall (12). The sealed container (100) is further provided with an opening and locking mechanism (3) slidably connected to the cover body (2) and the container body (1). The opening and locking mechanism (3) is provided with a push member (31) slidably secured in the slide groove (121), and a connecting rod (32) rotatably secured on the push member (31) and mounted inside the cover body (2). The connecting rod (32) is urged upward by the push member (31) to push the cover body (2) backward, so as to expose the accommodation cavity (10) to the outside.
