Solution Overview

Problem

Airtight boxes in the market face issues with inconvenient and noisy opening and locking mechanisms, requiring multiple actions and generating noise due to rolling mechanisms, which also reduce the effective volume of the drawer.

Innovation Solution

An airtight box design featuring a sliding groove and a connecting rod mechanism that allows the cover to be opened and locked with a single backward pushing action, eliminating the need for rolling and minimizing noise, while maintaining the box's airtight seal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a rolling mechanism is used for opening and locking the airtight box, then the locking function is achieved, but noise is generated and the effective volume of the drawer is reduced

Engineering Contradiction:

Improveopening and locking operationVSAvoidnoise

Core Design Contradiction:

Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent replaces the traditional rolling mechanical system with a sliding rod mechanism. The sliding rod moves linearly within grooves to achieve the opening and locking function, eliminating the rolling action that generates noise. The connecting rod translates the linear motion of the pushing member into the necessary movements for opening/closing and locking/unlocking without any rolling components.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent removes the rolling mechanism entirely from the system. By extracting the rolling function and replacing it with a sliding-based mechanism, the noise-generating component is eliminated while preserving the essential opening and locking functionality through alternative mechanical means.

Inventive Principle:

Principle #2Taking out (Extraction)

2Ease of operation

If a rolling mechanism is used for opening and locking the airtight box, then the locking function is achieved, but the effective volume of the drawer is reduced due to rolling space requirements

Engineering Contradiction:

Improveopening and locking operationVSAvoideffective volume of drawer

Core Design Contradiction:

Ease of operationVSVolume of moving object

Solution Approach 1:

The patent substitutes the space-consuming rolling mechanism with a compact sliding rod system. The sliding rod moves within grooves that require minimal space, and the connecting rod efficiently transfers motion without needing the additional rolling space that would reduce drawer volume.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the motion dimension from rolling (which requires radial space) to linear sliding (which requires only linear space within grooves). This dimensional change allows the mechanism to occupy less overall space, preserving more effective drawer volume while achieving the same opening and locking function.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Reliability

If multiple actions are required for opening and locking the airtight box, then the locking function is achieved, but the operation becomes inconvenient

Engineering Contradiction:

Improvelocking functionVSAvoidopening and locking operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent merges the opening/closing action and the locking/unlocking action into a single integrated operation. By connecting the pushing member to both the cover and the locking mechanism through the connecting rod, one linear pushing motion simultaneously achieves both functions, eliminating the need for separate rolling and locking actions.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The connecting rod is pre-configured in the mechanism so that when the pushing member moves, it automatically triggers both the cover movement and the locking engagement in the correct sequence. This preliminary arrangement of components ensures that the proper actions occur automatically as part of the single pushing motion, improving convenience while maintaining reliable locking.

Inventive Principle:

Principle #10Preliminary action

AI summary

There is provided an airtight box, comprising a box body and a cover covering the box body to close the box body tightly. The box body is provided with a receiving chamber with an opening which opens upwards and two side walls respectively located on both sides of the receiving chamber. A sliding groove extending longitudinally is provided on an outer side of each side wall. The airtight box is further provided with an opening and locking mechanism slidably connecting the cover and the box body. The opening and locking mechanism is provided with a pushing member slidably fixed in the sliding groove and a connecting rod rotatably fixed on the pushing member and mounted inside the cover. The connecting rod, under an action of the pushing member, presses upwards and drives the cover backwards to expose the receiving chamber to the outside.
