Solution Overview

Problem

Existing sealing devices for lithium batteries face difficulties in pressurization and exhibit poor standing effects due to the downward pressure exerted during inflation, which affects the sealability between the lower and upper covers.

Innovation Solution

A sealing box with an elastic sealing ring and inflation hole that deforms to fit closely against the groove walls, and a standing device with clamping jaw assemblies and floating structures to ensure proper alignment and clamping of the covers, maintaining sealability under pressure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a conventional bottle is placed in a recycling bin, then it occupies space in the bin, but it may tip over and cause contamination or require additional handling

Engineering Contradiction:
Improvestability of bottle in recycling binVSAvoidcomplexity of bottle structure
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The bottle is equipped with a standing device that extends laterally from the bottle body, transforming the bottle from a purely vertical cylindrical form into a three-dimensional structure with lateral support elements. This dimensional extension provides stability by creating a wider base of support without significantly increasing the bottle's vertical footprint in the recycling bin.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The standing device is designed as a separate, detachable component from the bottle body, allowing the bottle to be segmented into functional parts: the container portion and the stabilizing portion. This segmentation enables the standing feature to be added only when needed for recycling purposes while maintaining the simplicity of the basic bottle structure for other uses.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If a bottle has a wide base for stability, then it is more stable in the recycling bin, but it occupies more space in the bin

Engineering Contradiction:
Improvestability of bottle in recycling binVSAvoidfootprint of bottle in recycling bin
Core Design Contradiction:
Stability of the object's compositionVSArea of stationary object

Solution Approach 1:

Instead of expanding the bottle's base area in the horizontal plane, the standing device utilizes the vertical dimension by creating lateral extensions that fold out or extend only when the bottle is being positioned for recycling. This allows the bottle to maintain a small horizontal footprint during storage while providing stability when needed.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The standing device incorporates movable or collapsible elements that can transition between a compact state (when not in use) and an extended state (when providing stability). This dynamic behavior allows the bottle to adapt its footprint based on whether it needs to be stored compactly or stabilized for recycling processing.

Inventive Principle:
Principle #15Dynamics

3Stability of the object's composition

If a standing device is added to the bottle, then the bottle remains upright in the recycling bin, but the bottle structure becomes more complex

Engineering Contradiction:
Improveupright positioning of bottleVSAvoidcomplexity of bottle structure
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The standing device is designed as a separate, detachable component from the bottle body, allowing the bottle to be segmented into functional parts: the container portion and the stabilizing portion. This segmentation enables the standing feature to be added only when needed for recycling purposes while maintaining the simplicity of the basic bottle structure for other uses.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The standing device is designed to automatically position itself or activate when the bottle is placed in the recycling bin, without requiring user intervention or complex control mechanisms. The structural design itself provides the stabilizing function through passive geometric or mechanical means, such as lateral extensions that naturally contact the bin surface to prevent tipping.

Inventive Principle:
Principle #25Self-service

AI summary

A sealing box and a standing device are disclosed by the present application. The sealing box includes an upper cover (10); a lower cover (20) which is detachably connected to the upper cover (10) and encloses with the upper cover (10) to form an accommodating chamber (a), and defines a sealing groove (21) toward the upper cover (10) and an inflation hole (22) capable of inflating airflow into the sealing groove (21); and an elastic sealing ring (30) which includes a sealing end (32) sealedly contacting the upper cover (10) and a deformation end (33) extending into the sealing groove (21). The deformation end (33) is deformed under action of the airflow and squeezes the sealing groove (21), so as to apply a force to the lower cover (20) toward the upper cover (10).
