Solution Overview

Problem

Existing staple dispensing devices face issues with complexity, jamming, and inability to handle three-dimensional components due to unstable positioning on vibrating tables, limiting their effectiveness in assembly line operations.

Innovation Solution

A device featuring a main magazine, a temporary storage tray with individual housings for stable component positioning, an optical detection system, and a transfer system controlled by an electronic unit to identify and pick up components in stable positions, ensuring efficient transfer to a processing zone.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If a vibratory bowl feeder and guide rails are used to convey staples, then staple feeding is automated, but the system becomes complex and blockages occur due to incorrect staple positioning

Engineering Contradiction:
Improveautomated staple feedingVSAvoidsystem complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The device segments the staple storage and positioning function into individual housings within the temporary storage tray, rather than using a continuous vibratory bowl feeder system. Each housing acts as an independent positioning unit, simplifying the overall system while maintaining automation capability through the translation mechanism of the tray.

Inventive Principle:
Principle #1Segmentation

2Extent of automation

If a vibratory bowl feeder and guide rails are used to convey staples, then staple feeding is automated, but blockages occur due to incorrect staple positioning

Engineering Contradiction:
Improveautomated staple feedingVSAvoidblockage frequency
Core Design Contradiction:
Extent of automationVSReliability

Solution Approach 1:

The device performs preliminary positioning of staples in individual housings before transfer to the robot gripper. The temporary storage tray with individual housings pre-positions each staple in a known, stable orientation, eliminating the positioning uncertainties that cause blockages in continuous feeding systems.

Inventive Principle:
Principle #10Preliminary action

3Stability of the object's composition

If a vibrating table is used to position components, then components settle into stable positions, but three-dimensional components cannot achieve stable positioning due to their shape

Engineering Contradiction:
Improvecomponent positioning stabilityVSAvoidcompatibility with component shapes
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

Instead of using a single vibrating table surface, the device segments the positioning surface into individual housings. Each housing is specifically configured to receive and stabilize a single component in a predetermined position, accommodating various component shapes including three-dimensional staples with bullet-shaped feet and disc-shaped heads.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each housing in the temporary storage tray has specific geometric characteristics tailored to hold components in stable positions. The individual housings provide localized support surfaces and constraints that adapt to different component geometries, enabling stable positioning of three-dimensional components that cannot be stabilized on a flat vibrating table.

Inventive Principle:
Principle #3Local quality

4Stability of the object's composition

If individual housings are used in the temporary storage tray, then component positioning stability improves, but device complexity increases

Engineering Contradiction:
Improvecomponent positioning stabilityVSAvoidtray structure complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The temporary storage tray with individual housings serves multiple functions: it stores components, positions them in stable orientations, and facilitates their transfer to the robot gripper. The housings are designed to be universally compatible with the specific staple geometry (bullet-shaped foot, disc-shaped head), eliminating the need for separate positioning mechanisms.

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