Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional cable fastening devices are used, then cable securing is achieved, but flexibility and ease of assembly are insufficient

Engineering Contradiction:
Improveease of assemblyVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The cable fastening device is divided into multiple independent cable receiving bays within a single housing, allowing individual cables to be secured separately while maintaining overall device simplicity. Each bay can be accessed and operated independently, improving ease of assembly and cable management.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The housing structure serves multiple functions simultaneously: it provides mechanical support, defines cable routing paths, contains strain relief mechanisms, and organizes multiple cable receiving bays. This multi-functionality reduces the need for additional separate components, enhancing ease of assembly.

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

2Adaptability or versatility

If small diameter cables are handled, then cable accommodation is achieved, but securing reliability is insufficient

Engineering Contradiction:
Improvecable size accommodationVSAvoidsecuring reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

Each cable receiving bay is equipped with dedicated strain relief units and securing structures specifically designed to accommodate cables of various diameters. The local adaptation of securing mechanisms to each bay's specific cable ensures reliable fixation even for small diameter cables.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The device incorporates adjustable or flexible securing parameters within each cable receiving bay, such as movable clamps or adaptable strain relief elements, that can be adjusted to match the specific diameter and characteristics of the cable being secured, ensuring reliable fixation across different cable sizes.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If multiple cables are managed, then cable organization is achieved, but assembly time increases

Engineering Contradiction:
Improvemulti-cable handlingVSAvoidassembly time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The housing is segmented into multiple cable receiving bays that are arranged in an organized manner, allowing multiple cables to be routed and secured simultaneously or sequentially without interference. This segmentation enables parallel assembly operations, reducing total assembly time.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The housing structure is pre-configured with defined cable routing paths, pre-positioned strain relief units, and pre-formed cable receiving bays. This preliminary arrangement of components guides the assembly process and reduces the time required to organize and secure multiple cables.

Inventive Principle:
Principle #10Preliminary action

4Reliability

If strain relief is provided, then cable protection is achieved, but device complexity increases

Engineering Contradiction:
Improvestrain reliefVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The strain relief units are integrated directly into the cable receiving bays and housing structure, combining the strain relief function with the cable securing and routing functions. This merging eliminates the need for separate strain relief components, maintaining device simplicity while providing effective cable protection.

Inventive Principle:
Principle #5Merging (Combining)
