Solution Overview

Problem

Existing disposable electronic atomization devices lack a quick-disassembling function for battery cores, making it inconvenient to remove and recover the battery cores, which can lead to waste and environmental pollution.

Innovation Solution

A battery assembly is designed with a holder, a battery protection tube, and a bottom cover that can be rotated to switch between a locked and unlocked state, allowing for easy removal of the battery core without professional tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the battery housing is designed to be permanently sealed, then the structural integrity and protection of the battery core is improved, but the ease of removing the battery core deteriorates

Engineering Contradiction:
Improvestructural integrityVSAvoidease of removing battery core
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The battery housing is segmented into a main body and a detachable bottom cover connected by buckle parts. This segmentation allows the bottom cover to be easily removed from the holder through rotational movement, enabling battery core access while maintaining structural integrity during use. The buckle connection divides the housing into separable components that can be quickly assembled and disassembled.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection between the bottom cover and holder transitions from a static permanent seal to a dynamic detachable buckle connection. The bottom cover can rotate relative to the holder to switch between locked and unlocked states, providing dynamic control over battery core accessibility while maintaining reliability when locked.

Inventive Principle:
Principle #15Dynamics

2Reliability

If professional tools are required to open the battery housing, then the protection of the battery core is improved, but the ease of operation for consumers deteriorates

Engineering Contradiction:
Improvebattery core protectionVSAvoidease of disassembly for consumers
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The buckle connection mechanism is designed to be operated directly by consumers without requiring professional tools. The bottom cover can be easily rotated and detached from the holder by hand, enabling consumers to perform battery core removal themselves. This self-service capability eliminates the need for specialized opening tools while maintaining adequate protection during normal use.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the battery housing is designed for easy disassembly, then the ease of recovering battery core is improved, but the structural stability deteriorates

Engineering Contradiction:
Improveease of battery core recoveryVSAvoidstructural stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The housing is divided into a stable main body and a detachable bottom cover section. The buckle connection provides a stable locked state during normal operation while allowing easy separation when needed. This segmentation enables the structure to maintain stability when assembled and facilitates easy disassembly for battery core recovery.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The buckle connection transitions between locked and unlocked states through rotational movement of the bottom cover. This dynamic mechanism provides structural stability when locked for normal use, yet enables easy disassembly for battery core recovery without compromising the inherent stability of the housing components themselves.

Inventive Principle:
Principle #15Dynamics

AI summary

The present disclosure relates to the field of electronic atomization technologies, and in particular, to a battery assembly and an electronic atomization device. The battery assembly includes a holder configured to mount a battery core, a battery protection tube, and a bottom cover located on one end of the battery protection tube. The battery protection tube is sleeved on the holder and covers the battery core, a first buckle part is arranged on the bottom cover, and a second buckle part configured to the first buckle part is arranged on the holder. The bottom cover is rotatable relative to the holder, so that the first buckle part is in a buckle connection with the second buckle part, or the first buckle part is separated from the second buckle part. In the present disclosure, the bottom cover is detachably connected to the holder, the battery core can be removed, and the bottom cover can be switched between a locked state and an unlocked state provided that the bottom cover is rotated manually, thereby improving convenience of removal.
