Carrier Assembly Lock That Holds the Release Button Open

Solution Overview

Problem

Conventional baby sleeping box and stroller frame assemblies require simultaneous operation of a releasing button and manual removal, making the process inconvenient.

Innovation Solution

An assembling structure with a releasing button and locking member that switches to an unlocked position upon operation, locked by a holding device, allowing easy disassembly by keeping the locking member unlocked.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a releasing button is used to unlock the locking member, then the locking can be released, but the releasing button must be continuously pressed during removal, making the operation inconvenient

Engineering Contradiction:

Improvelocking reliabilityVSAvoidoperation convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The holding device is activated in advance by the releasing button to lock the releasing button in the pressed position before the actual removal action is completed. This preliminary action maintains the unlocking state throughout the removal process, eliminating the need for continuous pressing and improving operational convenience while preserving locking reliability.

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If the releasing button is made spring-loaded to auto-reset, then the button automatically returns to initial position, but the locking member may re-engage during removal, causing safety issues

Engineering Contradiction:

Improvebutton operationVSAvoidunlocking reliability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The holding device is activated in advance by the releasing button to lock the releasing button in the pressed position before the actual removal action is completed. This preliminary action maintains the unlocking state throughout the removal process, eliminating the need for continuous pressing and improving operational convenience while preserving locking reliability.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If the releasing button is held pressed manually throughout removal, then the locking member remains unlocked, but the user must maintain continuous pressure, increasing operational complexity

Engineering Contradiction:

Improveunlocking reliabilityVSAvoidoperation steps

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The holding device is activated in advance by the releasing button to lock the releasing button in the pressed position before the actual removal action is completed. This preliminary action maintains the unlocking state throughout the removal process, eliminating the need for continuous pressing and improving operational convenience while preserving locking reliability.

Inventive Principle:

Principle #10Preliminary action

AI summary

Disclosed is an assembling structure, including: a body structure; a releasing button; a locking member, and a holding device. The releasing button and the locking member are installed on the body structure, and the locking member has a locked position and an unlocked position. When a releasing operation is performed, the releasing button drives the locking member to switch from the locked position to the unlocked position. The holding device is arranged in the body structure and configured to lock the releasing button at a position, keeping the locking member at the unlocked position. In addition, the present application discloses an assembling mechanism and a carrier.
