Solution Overview

Problem

Existing sorting machines with handlers require time-consuming and space-consuming tool-changing operations, which lead to idle time in machine operation and are not compatible with the compact footprint needed for handling multiple gripping heads and stacked workpieces.

Innovation Solution

A gripping head for a sorting machine equipped with a revolver-shaped tool carrier that allows for quick tool selection and use without the need for a separate tool carrier, enabling tools to be used directly from the carrier and reducing operational downtime.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If tools are stored in a separate tool carrier area, then tool storage capacity is improved, but tool changing time and operational downtime increase

Engineering Contradiction:
Improvetool storage capacityVSAvoidtool changing time
Core Design Contradiction:
Quantity of substanceVSLoss of time

Solution Approach 1:

The patent merges the tool carrier with the gripping head by mounting multiple tools directly on the gripping head body. This integration eliminates the need for separate tool carrier areas and the displacement operations required to access tools, thereby reducing tool changing time while maintaining adequate tool storage capacity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent arranges multiple tools in a stacked configuration on the gripping head body, utilizing vertical space rather than horizontal displacement. This dimensional reorganization allows tools to be accessed by vertical movement of the gripping head to different height levels, eliminating the need for lateral displacement to a separate tool carrier area.

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

2Productivity

If multiple tools are mounted on a multi-tool head, then tool changing operations are eliminated, but the footprint and bulk of the gripping head increases

Engineering Contradiction:
Improveoperational continuityVSAvoidgripping head footprint
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The patent stacks multiple tools vertically on the gripping head body, utilizing the vertical dimension rather than expanding horizontally. This allows multiple tools to be mounted without significantly increasing the gripping head's horizontal footprint, maintaining compatibility with the compact spatial requirements of sorting machines.

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

Solution Approach 2:

The patent nests multiple tools within the compact structure of the gripping head body, arranging them in a space-efficient configuration. The tools are positioned to utilize available internal and external surfaces of the gripping head, minimizing the overall bulk while accommodating multiple tool types.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Adaptability or versatility

If a separate tool carrier is used, then tool versatility is improved, but the complexity of tool changing operations increases

Engineering Contradiction:
Improvetool varietyVSAvoidtool changing mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the tool carrier functionality directly with the gripping head structure. Tools are mounted on the gripping head body itself, eliminating the need for separate tool carrier mechanisms and the complex displacement operations required to access tools stored elsewhere.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent extracts the tool carrier function from a separate component and integrates it directly into the gripping head. This eliminates the intermediate step of displacing to a separate tool carrier, simplifying the overall tool changing process while maintaining the ability to store and access multiple tool types.

Inventive Principle:
Principle #2Taking out (Extraction)
