Solution Overview

Problem

Existing enclosure structures, such as doors and windows, have complex and laborious mounting processes and are costly due to their intricate locking mechanisms.

Innovation Solution

An enclosure structure comprising an enclosure body with a clearance hole, a handle with an elastic connecting portion, a boss, and a pressing portion that cooperates to form a slot, allowing for easy door opening and closing without separate installation, using a limiting member that can be stuck or detached from the slot via the elastic action of the handle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a complex locking structure is used to achieve reliable enclosure closure, then the reliability of the enclosure structure is improved, but the device complexity and manufacturing cost increase

Engineering Contradiction:

Improvereliability of enclosure closureVSAvoidcomplexity of locking structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The locking function is segmented into two independent components: a limiting member on the movable end portion and a slot on the fixed end portion. This segmentation allows each component to be simple in structure while collectively achieving reliable locking when engaged.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The complex locking mechanism is extracted and replaced with a simple limiting member that can be stuck into or detached from the slot. This extraction eliminates the need for intricate locking structures while maintaining the essential locking function.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If a separate locking structure is added to the enclosure body, then the enclosure closure function is improved, but the manufacturing cost and production time increase

Engineering Contradiction:

Improveenclosure closure functionVSAvoidmanufacturing cost and production time

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The locking function is merged into the basic structural components of the enclosure body. The limiting member and slot are formed as integral parts of the enclosure structure during normal manufacturing, eliminating the need for separate locking structure production and assembly.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The enclosure body structures (limiting member and slot) serve dual purposes: they form the basic enclosure structure and simultaneously provide the locking function. This self-service approach eliminates the need for additional locking components and simplifies manufacturing.

Inventive Principle:

Principle #25Self-service

3Reliability

If a traditional locking mechanism is installed on doors and windows, then the enclosure structure achieves proper closure, but the mounting process becomes laborious and time-consuming

Engineering Contradiction:

Improveclosure functionVSAvoidmounting time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The limiting member and slot are pre-formed as integral parts of the enclosure body during manufacturing. This preliminary action eliminates the need for separate installation steps, as the locking components are already in place and ready for use.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The enclosure body structures automatically provide the locking function through their inherent design. The limiting member and slot work together without requiring additional installation or configuration, making the mounting process straightforward and quick.

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

The solution simplifies the operation and reduces costs by allowing direct integration of the handle on the enclosure body, enabling convenient door operation and reducing manufacturing expenses, while being applicable to various enclosure types like doors, windows, and storage boxes.

Implementation Method 1

the elastic connecting portion is deformed by the force, the notch of the slot is enlarged, so that the limiting member that is stuck in the slot is detached from the slot or the limiting member can be stuck in the slot

AI summary

An enclosure structure including an enclosure body, a handle, and a slot. The enclosure body includes a first end portion and a second end portion that are disposed oppositely to each other. The enclosure body is provided with a clearance hole, and the clearance hole is disposed between the first end portion and the second end portion, and the handle is rotatably disposed on the enclosure body and is disposed between the clearance hole and the first end portion. The handle includes an elastic connecting portion, a boss, and a pressing portion. The pressing portion is configured to control a limiting member to be stuck in or detached from the slot. The elastic connecting portion protrudes out of the enclosure body and two ends thereof are connected to the enclosure body and the boss, respectively; the boss and the enclosure body are spaced apart.
