Solution Overview

Problem

Existing distribution modules for telecommunications and data technology face challenges with wire routing and tension protection, particularly in high packing density scenarios where controlled wire routing is limited and wire detachment is a risk, especially under oblique tensile forces.

Innovation Solution

A distributor module with a plastic housing featuring integrated deflection elements acting as wire pull fuses, allowing wires to be routed from the rear to the front, ensuring they are deflected close to the connection contacts, thus providing enhanced force diversion and maintaining short twisted pair lengths for improved transmission behavior.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If insulation displacement contacts are set at an angle to cut into the wire core, then wire connection reliability is improved, but wire detachment risk increases under oblique tensile forces

Engineering Contradiction:
Improvewire connection reliabilityVSAvoidwire detachment resistance
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

A deflection element is introduced as an intermediary component between the wire and the insulation displacement contact. This deflection element redirects oblique tensile forces away from the contact slot, preventing force components that would cause wire detachment while maintaining the cutting action of the contact on the wire core.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Area of stationary object

If high packing density is used in distribution modules, then space utilization is improved, but controlled wire routing capability deteriorates

Engineering Contradiction:
Improvespace utilizationVSAvoidwire routing control
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The deflection element extends in the longitudinal direction of the module, creating a new spatial dimension for force management. By positioning the deflection element laterally offset from the contact slot, it intercepts tensile forces before they reach the contact, enabling high packing density while maintaining wire routing control.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If additional wire strain relief devices are added to protect against wire detachment, then wire protection is improved, but manufacturing and assembly costs increase

Engineering Contradiction:
Improvewire protectionVSAvoidmanufacturing and assembly costs
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The deflection element is integrated directly into the housing structure of the distribution module, merging the wire protection function with the existing housing. This eliminates the need for separate, loosely fitted wire strain relief devices, reducing part count and simplifying manufacturing and assembly while maintaining wire protection capability.

Inventive Principle:
Principle #5Merging (Combining)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution ensures reliable wire connection and protection against detachment, allowing for efficient and stable routing of twisted pairs, enhancing the module's stability and transmission properties while minimizing manufacturing and assembly costs.

Implementation Method 1

If the wire is then pulled diagonally upwards over the edge, the force component runs parallel to the contact slot no longer through the contact, but through the laterally offset edge. This reliably protects the wire from being unintentionally pulled out.
