Solution Overview

Problem

Current olive vibrators for harvesting small fruits have a limited field of action and complex architecture, whether using a single comb member or two comb members arranged side by side.

Innovation Solution

An electroportable vibrator design featuring one or two comb members connected to the tool head by individual pivots, with the pivot positioned aligned or out of alignment with the tool head's attachment point and the eccentric's center of rotation, allowing for a wider field of action while maintaining a simple architecture, and utilizing a single actuator to drive the comb members.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of moving object

If two comb members are arranged side by side to increase the field of action, then the field of action is improved, but the device complexity increases

Engineering Contradiction:
Improvefield of actionVSAvoidarchitecture complexity
Core Design Contradiction:
Area of moving objectVSDevice complexity

Solution Approach 1:

The patent merges the driving mechanism for multiple comb members into a single shared eccentric actuator. Instead of providing separate actuators for each comb member, one eccentric mechanism drives all comb members simultaneously through individual pivots, reducing the number of driving components while maintaining the ability to shake multiple branches

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single eccentric actuator serves multiple functions by driving several comb members at once. This universal driving mechanism can accommodate one or two comb members depending on the harvesting needs, providing versatility without requiring additional specialized components for each configuration

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

2Device complexity

If a single comb member is used to simplify the architecture, then the device complexity is reduced, but the field of action is limited

Engineering Contradiction:
Improvearchitecture complexityVSAvoidfield of action
Core Design Contradiction:
Device complexityVSArea of moving object

Solution Approach 1:

The patent extends the field of action of a single comb member by optimizing its pivot position and orientation. The pivot is positioned aligned with and between the tool head attachment point and the eccentric center of rotation, creating a lever arm that maximizes the comb member's reach and coverage area without adding more comb members

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

3Area of moving object

If the pivot is positioned aligned with the tool head attachment point and eccentric center of rotation to maximize field of action, then the field of action is improved, but the balance and ergonomics may worsen

Engineering Contradiction:
Improvefield of actionVSAvoiduser comfort
Core Design Contradiction:
Area of moving objectVSEase of operation

Solution Approach 1:

The patent uses the tool head structure and pivot positioning to create a balanced system. The pivot is strategically positioned to distribute the mechanical loads generated by the eccentric motion, counterbalancing the forces to reduce vibrations and improve ergonomics while maintaining the optimized field of action

Inventive Principle:
Principle #8Anti-weight (Counterweight)
