Solution Overview

Problem

Conventional detachable notebook computers require two hands to remove a display screen from an accommodation slot, as continuous pressing is necessary to disengage the snap member from the fastening slot, making single-handed operation impossible.

Innovation Solution

An electronic device equipped with a snap release module that includes a slide member, elastic component, hook, and stop member, allowing the display screen to be assembled or removed with one hand by transitioning the slide member between snap and release positions using a single operating mechanism, with elastic forces facilitating automatic return to the snap position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional snap member is used in the accommodation slot, then the display screen can be securely fastened, but two hands are required to remove it due to continuous pressing being necessary

Engineering Contradiction:
Improvefastening securityVSAvoidremoval operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The snap member is segmented into a snap body and a separate pressing member. The pressing member can be independently actuated to release the snap engagement, allowing one-handed operation while maintaining secure fastening during normal use.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The snap member incorporates an elastic component that enables dynamic movement between engaged and disengaged states. The pressing member can dynamically shift the snap body to release the hook from the fastening slot, facilitating easy removal with one hand.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the snap member is pressed continuously to remove the display screen, then the hook can be moved out of the fastening slot, but single-handed operation becomes impossible

Engineering Contradiction:
Improvedisplay screen removalVSAvoidoperation process
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The pressing member acts as an intermediary between the user's finger and the snap body. It concentrates the pressing force onto the snap body's pressing surface, enabling effective release operation with a single finger without requiring continuous pressing with one hand while holding the display screen with the other.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If a simple snap mechanism is used, then the structure remains simple, but automatic reset functionality is not achieved

Engineering Contradiction:
Improvemodule structureVSAvoidreset functionality
Core Design Contradiction:
Device complexityVSExtent of automation

Solution Approach 1:

The elastic component provides self-service by automatically returning the snap body to its engaged position after release. When the pressing member is released, the elastic force automatically resets the snap mechanism without requiring manual intervention, achieving automatic reset functionality.

Inventive Principle:
Principle #25Self-service

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables single-handed assembly and disassembly of the display screen, eliminating the need for continuous pressing and enhancing user convenience by allowing the snap release module to automatically reset for subsequent use.

Implementation Method 1

The elastic component abuts between the housing and the slide member, to provide an elastic force when the slide member is located at the release position, so that the slide member resets to the snap position

Methodology Applied
Scientific EffectElastic force: Elasticity

AI summary

Disclosed is an electronic device (200), including a first housing (80), a second housing (90), and a snap release module (100). The first housing is provided with a fastening slot (81). The second housing (90) is provided with an accommodation slot (91). The snap release module (100) is accommodated in the accommodation slot (91), and includes a slide member (10), an elastic component (40), a hook (20), and a stop member (30). The slide member (10) reciprocates in a first axial direction (X). When the first housing is assembled to the second housing (90) in the second axial direction (Y), the slide member (10) is located at the snap position for the hook (20) to be buckled in the fastening slot (81), and the first housing presses the stop member (30) so that the stop member (30) abuts against the slide member (10). When the slide member (10) slides from the snap position to the release position, the stop member (30) stops the slide member (10) and the hook (20) is detached from the fastening slot (81).
