Solution Overview

Problem

Existing elbow screw joint systems face difficulties in aligning cable outlets, especially after installation, as they are fixed during assembly and cannot be subsequently adjusted.

Innovation Solution

An improved elbow screw joint system comprising a guide body, an insert with a rotatable guide section, and a cover, allowing for easy assembly and subsequent alignment adjustments by rotating the guide body and locking the alignment with the cover's threading.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the elbow screw joint system uses a fixed alignment during assembly, then the structure is simple and stable, but the alignment cannot be adjusted after installation

Engineering Contradiction:
Improvealignment adjustabilityVSAvoidjoint system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The guide section is designed to be rotatable within the guide body, transforming the fixed alignment into a dynamic, adjustable configuration. This allows the outlet axis to be reoriented after assembly by rotating the guide section to different angular positions, while the overall joint system structure remains relatively simple.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the elbow screw joint system allows subsequent alignment correction, then the adaptability is improved, but the assembly and locking process becomes more complex

Engineering Contradiction:
Improvealignment correction capabilityVSAvoidassembly and locking simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The guide section is pre-equipped with a threading on its upper end region, and the joint system includes a cover with corresponding threading. This preliminary preparation allows for simple screwing operations to lock the guide section at the desired angular position after alignment correction, maintaining ease of operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The angular position of the guide section can be changed by rotating it to different orientations. The threading mechanism then locks this new parameter (angular position) in place, enabling alignment correction while keeping the locking process simple through straightforward screwing operations.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If the guide section is rotatable for alignment adjustment, then the ease of operation is improved, but the stability of the locked position may be compromised

Engineering Contradiction:
Improvealignment adjustment easeVSAvoidlocked position stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The joint system is segmented into distinct components: the guide body, the rotatable guide section, and the cover. This segmentation allows the guide section to be independently rotated for alignment adjustment while the cover provides a separate locking mechanism that secures the guide section at the desired position, maintaining both ease of adjustment and locked position stability.

Inventive Principle:
Principle #1Segmentation

AI summary

An elbow screw joint system for screw-connecting and rerouting elongate shaped parts includes a guiding body, an insert and a cover. The insert has a guiding section rotatably arranged at least partially inside the guiding body. The guiding body has a guiding recess and an outlet recess. The guiding recess has a guiding axis and extends along the guiding axis from a receiving side to an opposite head side. The outlet recess has an outlet axis and extends from an outlet side, along the outlet axis, to the guiding recess. Also, the guiding axis and the outlet axis are at an angle relative to one another. The guiding section has a screw thread at an upper end region which is associated with the head side of the guiding body, and the cover is screw-connected, from the head side, to the screw thread of the guiding section.
