Solution Overview

Problem

Existing reel support systems require additional space for hinged doors, leading to increased container size and limited orientation flexibility, and protruding gearmotor assemblies complicate storage and deployment.

Innovation Solution

A support device with a hydraulic-oil control unit and a centred articulated connection allows the reel to rotate within a compact, enclosed structure, integrating a hydraulic gearmotor inside the tubular shaft and enabling the support to pivot, reducing the need for external space and optimizing storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If hinged doors are used on the container, then access to the reel is enabled, but additional sweeping space is required around the container

Engineering Contradiction:
Improveaccess to reelVSAvoidspace around container
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The container doors are replaced with a rolling door mechanism that moves horizontally along tracks, eliminating the need for outward sweeping motion. This dynamic solution allows the door to retract into the container body rather than requiring external clearance space, resolving the contradiction between ease of access and space requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The door opening mechanism transitions from a two-dimensional outward rotation (hinged doors requiring lateral space) to a one-dimensional linear movement (rolling door along tracks). This dimensional change allows the door to open without requiring additional external space, as the movement occurs within the plane of the container facade.

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

2Ease of operation

If gearmotor assembly protrudes from the reel side, then reel rotation is enabled, but more space inside the container is required

Engineering Contradiction:
Improvereel rotationVSAvoidspace inside container
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The gearmotor assembly is nested within the tubular shaft of the reel rather than protruding from it. The hydraulic motor and gear mechanism are housed inside the hollow cylindrical structure of the reel shaft, eliminating external protrusions and maximizing the usable volume within the container while maintaining full rotational functionality.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

A hydraulic-oil control unit with a hydraulic motor is used to drive the reel rotation, replacing traditional electric gearmotors. The hydraulic system is integrated within the reel structure, and the hydraulic motor's compact design allows it to fit within the tubular shaft, reducing the space required inside the container.

Inventive Principle:
Principle #29Pneumatics and hydraulics

3Stability of the object's composition

If reel support is fixed, then structural stability is maintained, but orientation flexibility is lost

Engineering Contradiction:
Improvestructural stabilityVSAvoidorientation flexibility
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The fixed reel support is replaced with a rotatable support mechanism that allows the entire reel assembly to be rotated to different orientations. The support structure includes a rotatable base with articulated connections, enabling the reel to be positioned at various angles while maintaining structural stability through controlled mechanical joints and locking mechanisms.

Inventive Principle:
Principle #15Dynamics
