Solution Overview

Problem

Existing watch component distribution systems in automatic assembly installations are unreliable due to component accumulation and jamming, leading to manual intervention and increased production costs from components not being correctly gripped by the gripping arm, resulting in losses.

Innovation Solution

A vibrating device with interconnected compartments and inclined planes, a supply platform, and an articulated gripping arm, along with a sorting/selection device using air flow and guide portions to orient and grip components correctly, reducing manual intervention and losses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If a vibratory bowl feeder with ramp and feed channel is used to distribute watch components, then components can be automatically fed to the assembly machine, but components accumulate on the ramp or in the feed channel causing jams and system malfunctions

Engineering Contradiction:
Improveautomatic component feedingVSAvoidsystem reliability
Core Design Contradiction:
Extent of automationVSReliability

Solution Approach 1:

The vibratory device is divided into multiple compartments (first compartment for bulk storage, second compartment for controlled feeding) separated by a transfer zone. This segmentation prevents component accumulation by creating distinct functional zones, allowing reliable automatic feeding without jams.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Components are pre-oriented on the inclined plane before entering the feed channel. The inclination and vibration pattern prepare components in advance by aligning them properly, preventing accumulation and ensuring smooth transfer to the assembly machine.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If components are slightly oiled or have imperfect geometry, then they can be handled by the vibratory bowl feeder, but this causes excessive accumulation and requires manual intervention to restore operation

Engineering Contradiction:
Improvehandling of varied component conditionsVSAvoidcontinuous operation capability
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The system automatically manages component flow through vibration control and compartment design, eliminating the need for manual intervention. The vibratory mechanism self-regulates to prevent accumulation even with oiled or imperfect components, maintaining continuous operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The vibratory device uses dynamic vibration patterns that adapt to component conditions. By controlling vibration frequency and amplitude, the system handles varied component states (oiled, imperfect geometry) while maintaining steady flow and preventing accumulation.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If the gripping arm does not correctly grip components, then components fall outside the vibratory bowl, but this results in significant component losses and increased production costs

Engineering Contradiction:
Improvecomponent distribution functionVSAvoidcomponent loss
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

Components are pre-oriented and positioned correctly on the inclined plane before being presented to the gripping arm. This preliminary positioning ensures that when the gripping arm operates, components are already in the correct orientation, minimizing missed grips and component losses.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system incorporates sensors that detect component presence and orientation on the inclined plane, providing feedback to control the gripping arm timing. This ensures the gripping arm only activates when a component is properly positioned, preventing losses from incorrect gripping.

Inventive Principle:
Principle #23Feedback
