Solution Overview

Problem

Existing cable management systems are inefficient in terms of assembly, cost, and space utilization, particularly when managing optical fiber cables, as they often require separate trays with connection management units.

Innovation Solution

A modular cable management system comprising a cable management unit with a receiving space for drawer units, each with fixation units for connection management units, allowing flexible and space-efficient assembly and management of optical fiber cables, including features like snap connections, interchangeable connection management units, and cable strengthening members.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If separate trays with connection management units are used, then cable management functionality is provided, but assembly complexity and cost increase

Engineering Contradiction:
Improvecable management functionalityVSAvoidassembly complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The drawer unit integrates both cable management functionality and connection management units into a single unified structure. The fixation units are built-in components of the drawer unit itself, eliminating the need for separate trays and reducing assembly complexity while maintaining full cable management functionality.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If separate trays with connection management units are used, then cable management functionality is provided, but space utilization deteriorates

Engineering Contradiction:
Improvecable management functionalityVSAvoidspace utilization
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The drawer unit combines cable management and connection management functions into one integrated unit, eliminating the need for separate trays. This consolidation reduces the total space required while maintaining full cable management functionality.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If multiple separate components are used for cable management, then functionality is comprehensive, but manufacturing cost increases

Engineering Contradiction:
Improvecable management functionalityVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The drawer unit is manufactured as an integrated component with built-in fixation units, combining multiple functions into a single manufacturable part. This reduces the number of separate components that need to be produced and assembled, thereby lowering manufacturing costs while maintaining comprehensive cable management functionality.

Inventive Principle:
Principle #5Merging (Combining)

4Stability of the object's composition

If drawer units are fixed in position, then cable management is stable, but flexibility and adaptability decrease

Engineering Contradiction:
Improvecable management stabilityVSAvoidflexibility
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The drawer unit incorporates movable elements including sliding mechanisms and adjustable fixation units that can be positioned at different locations. This dynamic design allows the drawer unit to adapt to different cable management configurations while maintaining stable cable organization through the fixation units.

Inventive Principle:
Principle #15Dynamics
