Solution Overview

Problem

Existing denesting apparatuses face challenges in reliably and precisely denesting closely stacked objects with varying gap extensions between their edges, leading to issues like slipping or failure to contact the edges, resulting in incomplete denesting and interruptions in processing lines.

Innovation Solution

A denesting element with an elastically displaceable contact section that can adjust between extended and retracted positions, allowing it to securely fit within the gaps between objects and maintain contact, even in closely stacked configurations, by using an elastic element or pivot joint to facilitate reversible displacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional denesting apparatuses use fixed contact sections, then the structure is simple, but they cannot reliably contact edges of closely stacked objects with varying gap extensions

Engineering Contradiction:
Improvereliability of denestingVSAvoidcomplexity of denesting element
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The contact section is made elastically displaceable between extended and retracted positions, allowing it to dynamically adapt to varying gap extensions between stacked objects. This dynamic capability enables reliable contact with object edges regardless of stacking variations, resolving the contradiction between reliability and fixed structure simplicity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The contact section's position parameter is made variable through elastic displacement, allowing it to change between extended and retracted positions based on the actual gap extension. This parameter change capability enables the contact section to maintain reliable contact with object edges while accommodating variations in stacking configuration.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the contact section is always in the extended position, then contact with object edges is maximized, but the denesting element cannot adapt to varying gap extensions

Engineering Contradiction:
Improveadaptability to varying gap extensionsVSAvoidconsistency of contact
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The contact section's ability to displace elastically between extended and retracted positions provides adaptability to varying gap extensions while maintaining consistent contact reliability. The elastic displacement mechanism allows the contact section to adjust its position dynamically, ensuring reliable contact regardless of the specific gap extension encountered.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The contact section automatically adjusts its position through elastic displacement in response to varying gap extensions, without requiring external control or intervention. This self-adjusting capability enables the contact section to maintain reliable contact while adapting to different stacking configurations.

Inventive Principle:
Principle #25Self-service

3Productivity

If the denesting element rotates rapidly to achieve high-speed denesting, then productivity increases, but precise timing of denesting becomes difficult due to friction and vacuum forces

Engineering Contradiction:
Improvedenesting speedVSAvoidprecision of denesting timing
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The contact section is positioned in the extended state before denesting occurs, allowing it to be pre-inserted into the gap between object edges. This preliminary positioning ensures that when rapid rotation begins, the contact section is already in place to immediately engage the object edge, enabling both high-speed operation and precise timing control.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The elastic displacement mechanism replaces complex mechanical timing and positioning systems that would be required to achieve precise denesting timing at high speeds. The elastic element automatically manages the contact section's position, eliminating the need for sophisticated mechanical control systems while maintaining both speed and precision.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
