Solution Overview

Problem

Existing cable dispensing systems face issues such as spool movement during use, tripping hazards, and the need for multiple dispensers due to fixed central protrusions that don't fit all spool sizes, along with cumbersome assembly and disassembly.

Innovation Solution

A dispensing system with a support base featuring opposing distributed coupling surfaces, such as hook-loop or Velcro, that securely attach the spool to a rotary part, allowing easy assembly and disassembly without tools, and accommodating various spool sizes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed central protrusion is used to guide the cable during dispensing, then the cable dispensing function is achieved, but the system cannot accommodate different spool sizes and requires multiple dispensers

Engineering Contradiction:
Improvecompatibility with different spool sizesVSAvoidnumber of dispensers required
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The support base is designed with a universal interface system comprising a central recess and distributed coupling surfaces that can accommodate spools of different sizes through a single dispenser unit. The distributed coupling surfaces include multiple attachment points arranged in different patterns to match various spool configurations, eliminating the need for multiple specialized dispensers.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The coupling interface is segmented into multiple independent coupling surfaces distributed around the support base rather than a single fixed protrusion. This segmentation allows selective engagement with different spool sizes and configurations while maintaining a single universal dispenser design.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If a central protrusion passes through the hollow of the spool to enable rotation, then the spool can rotate during cable dispensing, but accidental removal of the spool may occur due to clearance between the protrusion and hollow

Engineering Contradiction:
Improvespool rotation during dispensingVSAvoidspool retention on support base
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The single central protrusion is segmented into multiple distributed coupling surfaces arranged around the support base. These multiple contact points eliminate clearance issues by providing numerous engagement points between the spool flanges and the support base, preventing accidental removal while maintaining rotation capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The coupling mechanism transitions from a single-point radial constraint to a multi-point distributed constraint system. The distributed coupling surfaces create constraints in multiple dimensions and orientations, providing superior spool retention while allowing rotational movement around the central axis.

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

3Device complexity

If the spool is not secured to the support base, then the system structure remains simple, but the spool moves longitudinally across the working space causing tripping hazards and requiring constant repositioning

Engineering Contradiction:
Improvestructure of support baseVSAvoidspool movement and tripping hazard
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The support base structure is segmented into a fixed base and a removable rotary part that can be easily attached and detached. The distributed coupling surfaces provide secure spool retention during operation while allowing quick removal when not in use, eliminating tripping hazards without requiring a permanently complex structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The coupling system transitions from a static permanent attachment to a dynamic removable attachment. The distributed coupling surfaces enable the spool to be securely fixed during cable dispensing operations and easily removed when needed, adapting the system's constraint level based on operational requirements.

Inventive Principle:
Principle #15Dynamics

4Ease of operation

If multiple parts are used in the dispensing system for assembly and disassembly, then the system can be transported, but the assembly and disassembly process becomes cumbersome and time-consuming

Engineering Contradiction:
Improvetransportability of dispensing systemVSAvoidassembly and disassembly time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The rotary part and support base are merged into a single integrated assembly through the distributed coupling surfaces, eliminating the need for multiple separate components. This unified design allows the entire dispensing system to be transported as one piece while maintaining the capability for quick spool changes when needed.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The distributed coupling surfaces are pre-configured in specific patterns on the support base, allowing spools to be quickly matched and attached without complex alignment procedures. This preliminary arrangement of coupling points significantly reduces assembly and disassembly time compared to systems requiring multiple parts and complex assembly sequences.

Inventive Principle:
Principle #10Preliminary action

AI summary

The present invention discloses a dispensing system for cable spools comprising a support base for supporting a spool as the cable is dispensed. The support base substantially extends over a plane perpendicular to the axis of the spool, that is, the imaginary axis of the cylinder of the spool that longitudinally passes through the hollow of the spool. The support base comprises a fixed part that rests on the work surface, and a rotary part rotating according to the axis of the hollow of the spool with respect to the fixed part. The spool is detachably secured to the rotary part. The dispensing system comprises opposing distributed coupling surfaces, which are respectively arranged on the rotary part and on a base of the spool to secure the spool to the rotary part.
