Solution Overview

Problem

Existing motorized tools require costly modifications and waste fluid when using fluid dispensing systems integrated with consumables, leading to inefficiencies and environmental issues due to the need for new consumables and fluid disposal.

Innovation Solution

A fluid dispensing device that couples to motorized tools, featuring a reservoir and dispensing valve, allowing independent attachment and detachment from consumables, enabling efficient fluid application without modifying the tool and reducing waste by reusing the dispensing system with interchangeable consumables.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If fluid dispensing systems are integrated with consumables, then fluid application is achieved, but the cost increases and waste is generated when consumables are replaced

Engineering Contradiction:
Improvefluid application capabilityVSAvoidfluid waste
Core Design Contradiction:
Ease of manufactureVSLoss of substance

Solution Approach 1:

The system is divided into separate components: a reusable fluid dispensing device and replaceable consumables. The dispensing device contains the fluid reservoir and dispensing mechanism, while consumables (polishing pads, sanding discs) attach to it. This segmentation allows the fluid dispensing system to be reused across multiple consumables, eliminating fluid waste when consumables are replaced.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The consumable acts as an intermediary between the tool and the work surface, while the fluid dispensing device serves as an intermediary between the fluid reservoir and the application point. This intermediary structure allows the fluid dispensing capability to be decoupled from the consumable, enabling reuse of the dispensing system.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If motorized tools are modified to include fluid dispensing mechanisms, then fluid application is enabled, but the tool complexity and cost increase

Engineering Contradiction:
Improvefluid dispensing capabilityVSAvoidtool structure
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The fluid dispensing device combines multiple functions into a single attachment: it houses the fluid reservoir, contains the dispensing mechanism, provides the coupling interface for consumables, and attaches to the existing tool. This merging approach enables fluid application without modifying the original tool structure.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The fluid dispensing device is designed as a universal attachment that can be coupled to various motorized turning tools and can accommodate different types of consumables. The standardized coupling system allows the same dispensing device to work with multiple tool types and consumable varieties, reducing overall system complexity.

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

3Ease of manufacture

If consumables integrate internal fluid reservoirs, then fluid application is achieved, but the consumable cost increases

Engineering Contradiction:
Improvefluid application capabilityVSAvoidconsumable cost
Core Design Contradiction:
Ease of manufactureVSQuantity of substance

Solution Approach 1:

The fluid reservoir and dispensing mechanism are extracted from the consumable and placed in a separate, reusable dispensing device. This extraction eliminates the need to embed expensive fluid storage systems in each consumable, thereby reducing consumable cost while maintaining fluid application capability.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

The present invention refers to a device that is coupled to motorised tools whose consumable or implement rotates, preferably tools of the portable or swivelling type, supplying fluids either to the surface on which the consumable or implement acts, or to the consumable or implement itself so that it performs its function correctly, having a reservoir in which pressure is generated for its use and the device and the tool or consumable that is used being independent and interchangeable, and having conventional means of attachment that allow it to be used in conventional tools without having to adapt the tool, the consumable or implement.
