Solution Overview

Problem

Existing systems for securing electronic devices, particularly medical display screens, face challenges in easy assembly and disassembly, often requiring complex operations and risking damage due to misalignment and protruding locking mechanisms.

Innovation Solution

A removable assembly system with a male and female part design, featuring radially distributed support and retaining teeth, a rotational guide surface, and an angular locking device with a latch mechanism, allowing secure and easy attachment and detachment with a single hand.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a complex locking mechanism with protruding elements is used to secure the device, then the reliability of connection is improved, but the ease of operation deteriorates due to difficulty in alignment and risk of damage

Engineering Contradiction:

Improveconnection reliabilityVSAvoidassembly ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent inverts the traditional locking mechanism by making the protruding elements (teeth) part of the stationary support structure rather than the movable device. The device has a recess that receives the support, with teeth that engage into corresponding grooves in the support. This inversion eliminates the need for protruding locking elements on the device itself, making assembly simpler and more reliable while maintaining secure connection.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent introduces an intermediary engagement mechanism consisting of相互配合 teeth and grooves that mediate between the device and support. These teeth engage into grooves to provide secure locking while allowing easy alignment through the grooved guidance paths, solving both the reliability and ease of operation requirements simultaneously.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If a secure locking mechanism is used to prevent device removal, then the reliability is improved, but the device complexity increases due to multiple locking components

Engineering Contradiction:

Improvelocking reliabilityVSAvoidlocking mechanism complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The locking mechanism is segmented into simple geometric features (teeth and grooves) distributed around the connection interface rather than a single complex locking component. Multiple teeth engage into corresponding grooves to provide secure locking through distributed engagement points, simplifying the overall device structure while maintaining high reliability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent inverts the traditional approach by placing the locking features (teeth) on the stationary support structure rather than on the movable device. The device contains recesses with corresponding grooves that receive and lock the support teeth, eliminating the need for complex active locking components on the device itself.

Inventive Principle:

Principle #13The other way round (Inversion)

3Reliability

If protruding locking elements are used to ensure secure connection, then the locking reliability is improved, but the ease of manufacture deteriorates due to additional components

Engineering Contradiction:

Improvelocking reliabilityVSAvoidmanufacturing simplicity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent inverts the traditional design by making the locking teeth part of the stationary support structure rather than the device. The device is manufactured with simple recesses and grooves that receive the pre-formed support teeth, simplifying device manufacturing while ensuring secure locking through the engaged teeth.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent extracts the complex locking features from the device and places them on the support structure. The device itself only requires simple recesses and grooves to be formed, which are easier to manufacture, while the support contains the more complex tooth features that provide the locking function.

Inventive Principle:

Principle #2Taking out (Extraction)
