Solution Overview

Problem

The complexity and handling of drive assembly components for double-leaf automatic sliding doors during storage, transport, and shipping are hindered by their relatively long element lengths, making them difficult to manage.

Innovation Solution

The drive assembly components are divided into first and second parts along their element length, allowing for easier handling and assembly by positioning these parts side by side, with optional connections using connecting parts to form the complete assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If drive assembly elements are made as single long components to cover the entire door length, then the structural integrity and continuity of the drive assembly is improved, but the ease of handling during storage, transport, and shipping deteriorates

Engineering Contradiction:
Improvestructural integrity of drive assemblyVSAvoidease of handling during storage and transport
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The drive assembly elements are divided into multiple shorter segments along their length. Each segment can be independently handled, stored, and transported, significantly improving ease of operation while maintaining the ability to form a complete continuous drive assembly when joined together.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If drive assembly elements are divided into multiple parts to improve handling, then the ease of handling during storage and transport is improved, but the device complexity increases due to additional joining requirements

Engineering Contradiction:
Improveease of handling during storage and transportVSAvoidcomplexity of assembly process
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The drive assembly is segmented into multiple parts that can be easily joined using simple connecting elements, reducing the overall complexity of the assembly process while maintaining handling advantages.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple segmented parts are designed to be joined together using straightforward connection mechanisms, merging them into a complete drive assembly. This merging process is simplified through standardized interfaces and connecting elements, minimizing the increase in device complexity.

Inventive Principle:
Principle #5Merging (Combining)

3Manufacturing precision

If drive assembly elements are made as single long components, then the manufacturing precision and continuity of the drive path is improved, but the loss of time during assembly and installation increases

Engineering Contradiction:
Improveprecision of drive pathVSAvoidassembly and installation time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The drive assembly segments are pre-manufactured with precise dimensions and connection interfaces, allowing for high manufacturing precision to be achieved in controlled production conditions. This preliminary preparation enables faster on-site assembly, reducing the loss of time during installation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Segmentation allows each section to be manufactured with high precision independently, then quickly assembled together. The standardized interfaces and connecting elements enable rapid joining, offsetting the time that would otherwise be required to handle and install single long components.

Inventive Principle:
Principle #1Segmentation
