Solution Overview

Problem

Existing fruit piercers have an internal drive assembly that can contaminate fruit with lubricants during the piercing process, making them unsuitable for food processing, especially for fruits like cherries and cranberries.

Innovation Solution

A fruit piercing assembly with an external drive assembly that separates the drive mechanism from the frame assembly, preventing lubricant contamination and facilitating easier servicing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the drive assembly is located inside the frame assembly, then the structure is more compact, but lubricants from the drive assembly can contaminate the fruit during piercing

Engineering Contradiction:
Improvecompactness of frame assemblyVSAvoidlubricant contamination of fruit
Core Design Contradiction:
Volume of moving objectVSObject-affected harmful factors

Solution Approach 1:

The drive assembly is extracted from the internal location and positioned externally to the frame assembly. This separation removes the source of lubricant contamination from proximity to the fruit piercing operation, eliminating the harmful contamination effect while maintaining operational integration through external coupling mechanisms.

Inventive Principle:
Principle #2Taking out (Extraction)

2Device complexity

If the drive assembly is located inside the frame assembly, then integration is improved, but servicing becomes more difficult

Engineering Contradiction:
Improveintegration of drive assemblyVSAvoidservicing of drive assembly
Core Design Contradiction:
Device complexityVSEase of repair

Solution Approach 1:

The drive assembly is extracted from the integrated internal position and placed externally, making it accessible for servicing operations. This external positioning allows maintenance personnel to access, inspect, and repair the drive assembly without disassembling the frame structure, significantly improving ease of repair while maintaining functional integration through external mounting interfaces.

Inventive Principle:
Principle #2Taking out (Extraction)

3Object-affected harmful factors

If the drive assembly is moved outside the frame assembly, then lubricant contamination is prevented, but the device occupies more space

Engineering Contradiction:
Improvelubricant contamination preventionVSAvoidspace occupied by frame assembly
Core Design Contradiction:
Object-affected harmful factorsVSArea of stationary object

Solution Approach 1:

The piercer system is segmented into distinct functional modules: the frame assembly containing the piercing mechanism and the separately positioned drive assembly. This segmentation allows the drive assembly to be located in an external position that prevents lubricant contamination of fruit, while the overall system footprint is managed through modular configuration that optimizes space utilization.

Inventive Principle:
Principle #1Segmentation
