Solution Overview

Problem

Conventional cable glands require individual installation and removal of mounting aids, and once installed, the insert modules are only stabilized by vertical webs, lacking flexibility and stability.

Innovation Solution

A cable gland design comprising a first frame part with vertical webs and assembly aids that can be separated at predetermined breaking points, allowing insert modules of varying widths to be easily inserted and improving stability through a second frame part that can be securely attached.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If mounting aids are permanently fixed to the frame, then structural stability is improved, but flexibility for different insert module widths is reduced

Engineering Contradiction:
Improvestability of insert modules in frameVSAvoidflexibility for different insert module widths
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The mounting aid is segmented into a frame-part and a removable insert-part separated by a breaking point. The frame-part remains permanently fixed to provide structural stability, while the insert-part can be broken off at the predetermined breaking point to accommodate different insert module widths. This segmentation allows the system to maintain stability while gaining adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting aid transitions from a completely fixed static structure to a dynamic structure where the insert-part can be selectively removed. The breaking point enables controlled transformation of the mounting aid's configuration, allowing it to adapt dynamically to different insert module requirements while the frame-part maintains permanent attachment for stability.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If mounting aids are designed to be removable, then flexibility for different insert module widths is improved, but installation complexity increases

Engineering Contradiction:
Improveflexibility for different insert module widthsVSAvoidcomplexity of mounting aid installation
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mounting aid is pre-configured with a breaking point during manufacturing, creating a predetermined weak point that facilitates easy removal. This preliminary action eliminates the need for complex removal mechanisms or tools during installation, as the insert-part can be simply broken off at the pre-designed breaking point.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The insert-part of the mounting aid is designed as a disposable component that can be easily broken off and discarded after use. This approach simplifies the overall mounting aid design by eliminating the need for complex reusable mechanisms, as each insert-part is a simple, low-cost component designed for single-use removal.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Device complexity

If vertical webs alone stabilize insert modules, then device simplicity is maintained, but stability and security are insufficient

Engineering Contradiction:
Improvesimplicity of frame structureVSAvoidstability of insert modules in frame
Core Design Contradiction:
Device complexityVSStability of the object's composition

Solution Approach 1:

The solution merges two stabilization mechanisms: the permanent frame-part of the mounting aid that integrates with the vertical webs, and the additional support provided by the insert-part before removal. This combination provides enhanced stability during installation, and after removal, the frame-part continues to work with the vertical webs to maintain adequate stability with improved positioning accuracy.

Inventive Principle:
Principle #5Merging (Combining)
