Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If external connecting devices (clamps, screws) are used to assemble cable ducts, then the cable ducts can be connected to form assemblies, but the assembly process becomes cumbersome and requires additional components

Engineering Contradiction:
Improveease of assemblyVSAvoidcomplexity of assembly process
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The connecting device is merged with the cable duct body to form an integrated structure. The connecting device is formed in one piece on a cover wall of the channel body, eliminating the need for separate external connecting components and simplifying the assembly process

Inventive Principle:
Principle #5Merging (Combining)

2Strength

If connecting screws penetrate the duct wall to connect cable ducts, then the ducts can be securely connected, but the interior space for cables is reduced and cable laying is hindered

Engineering Contradiction:
Improveconnection strengthVSAvoidinternal cable space
Core Design Contradiction:
StrengthVSVolume of moving object

Solution Approach 1:

The connecting device is extracted from the interior space of the cable duct and positioned externally on the cover wall. The connecting device forms an external form-fitting connection that does not penetrate the duct wall, ensuring that the space available for accommodating cables is not impaired

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If multiple differently dimensioned multi-chamber cable ducts are kept in stock to provide various chamber layouts, then customized configurations can be achieved, but the stockpiling becomes complex

Engineering Contradiction:
Improvevariety of chamber layoutsVSAvoidcomplexity of stockpiling
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cable duct design with standardized cross-sections and integrated connecting devices enables universal applicability. Cable ducts can be combined in different numbers and configurations to provide sufficient overall capacity for various cable installation requirements, eliminating the need to maintain complex inventories of specialized duct types

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Ease of operation

If cable ducts are combined using force-fit connections by screwing duct walls together, then the ducts can be connected, but the installation becomes cumbersome and time-consuming

Engineering Contradiction:
Improveease of installationVSAvoidinstallation time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The connecting device is pre-formed as an integral part of the cable duct body during manufacturing. This preliminary integration eliminates the need for separate assembly steps involving external connecting devices, making the installation process simpler and faster

Inventive Principle:
Principle #10Preliminary action
