Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If profiles of different lengths are stored to accommodate varying door heights, then adaptability is improved, but storage space requirements and stock management complexity increase

Engineering Contradiction:

Improveadaptability to different door heightsVSAvoidstorage space

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The electromagnetic strip is divided into multiple modular base sections that can be connected end-to-end. Each base section contains an electromagnet and can be independently assembled, allowing the total length to be adjusted by varying the number of sections connected, thereby eliminating the need to store multiple pre-cut profiles of different lengths.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system transitions from static profiles of fixed lengths to a dynamic assembly system where the length can be adjusted on-demand by connecting or disconnecting base sections, enabling adaptability without requiring physical storage of multiple profile variants.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If profiles are cut to desired lengths to adapt to door height, then adaptability is improved, but installation time and operational complexity increase

Engineering Contradiction:

Improveadaptability to different door heightsVSAvoidinstallation time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

By pre-fabricating standardized base sections with integrated electromagnets and connection features, the system eliminates the need for on-site cutting operations. Installers simply connect the required number of pre-made sections, significantly reducing installation time while maintaining adaptability to various door heights.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The base sections are prepared in advance with all necessary components (electromagnets, electrical connections, interlocking features) already integrated during manufacturing. This preliminary preparation eliminates the need for cutting and assembly operations during installation, reducing both time and operational complexity.

Inventive Principle:

Principle #10Preliminary action

3Ease of manufacture

If a single profile length is used for all doors, then storage and stock management are simplified, but adaptability to different door heights deteriorates

Engineering Contradiction:

Improvesimplicity of storage and stock managementVSAvoidadaptability to different door heights

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

A single standardized base section design serves multiple functions and can be used to create electromagnetic strips of any required length by varying the number of sections connected. This universal module eliminates the need to manage multiple profile lengths in storage while maintaining full adaptability to different door heights.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system maintains a constant base section design (same dimensions, same components) but varies the total length parameter by changing the number of sections assembled. This allows simplified storage of identical standardized units while achieving adaptability through quantitative variation in assembly configuration.

Inventive Principle:

Principle #35Parameter changes
