Engineering Contradictions & Design Principles
Engineering 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
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.
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.
2Adaptability or versatility
If small diameter cables are handled, then cable accommodation is achieved, but securing reliability is insufficient
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.
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.
3Adaptability or versatility
If multiple cables are managed, then cable organization is achieved, but assembly time increases
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.
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.
4Reliability
If strain relief is provided, then cable protection is achieved, but device complexity increases
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.

AI summary
Proposed is a cable fastener device for fastening at least one cable (16a), more particularly an optical fibre cable, comprising at least one cable fastener inner element (10a; 10b) and at least one cable fastener outer element (12a; 12b), which are mounted for rotation relative to each other about an axis of rotation (14a; 14b) and are designed so that together, in at least one usage condition, they at least substantially completely surround the at least one cable (16a) in a cable circumference direction (18a).
