Solution Overview

Problem

Bulk bag discharge systems face challenges with products like salt that harden in wet or humid environments, causing unbalanced loads and premature failure of linear actuators due to bending moments, which traditional conditioning systems fail to address effectively.

Innovation Solution

A bulk bag discharge assembly with a main frame and bag conditioning assembly featuring pivotably coupled conditioner frames and massaging frames that apply forces to the sides and bottom of the bag, minimizing bending moments and optimizing force direction to condition the contents for discharge without damaging the bag or its suspension system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If linear actuators are fixedly mounted at both ends to condition bulk bag contents, then conditioning force is applied to the bag, but bending moments cause damage and premature failure of the actuators

Engineering Contradiction:
Improveconditioning forceVSAvoidactuator reliability
Core Design Contradiction:
ForceVSReliability

Solution Approach 1:

The conditioner is inverted so that the actuator is mounted at the distal end rather than the proximal end, allowing the conditioner to pivot about the actuator axis. This inversion eliminates bending moments on the actuator while maintaining conditioning force application to the bulk bag contents

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The conditioner is designed to pivot dynamically about the actuator axis during operation, allowing the conditioning arm to move through an arc as it contacts the bulk bag. This dynamic pivoting motion accommodates the uneven surfaces of bulk bags while keeping the actuator aligned with its mounting axis, preventing bending moments

Inventive Principle:
Principle #15Dynamics

2Productivity

If conditioner frames impact the bottom of the bulk bag to condition hardened materials, then effective conditioning is achieved, but damage is caused to the bag and its suspension system

Engineering Contradiction:
Improveconditioning effectivenessVSAvoidbag damage
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The conditioner is designed to impact only the side portions of the bulk bag while deliberately avoiding the bottom center area. This localized conditioning approach treats the hardened materials in the sides where access is available without applying damaging forces to the bag bottom and suspension system

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The conditioner frames are positioned asymmetrically to target side regions of the bulk bag rather than symmetrically impacting the bottom. This asymmetric design allows effective conditioning of side-wall material while preserving the integrity of the bag bottom and lifting loops

Inventive Principle:
Principle #4Asymmetry

AI summary

A bulk bag discharge assembly comprising a main frame assembly and a bag conditioning assembly. The main frame assembly defines a bulk bag receiving region having a discharge support base structurally configured to receive a bulk bag thereon for discharging. The bag conditioning assembly comprises opposing conditioner frames, each having a proximal end, a distal end, and an impact face, and at a proximal end, pivotably coupled to the main frame assembly. A powered cylinder is pivotably coupled to the main frame assembly at a first end, and to the first conditioner frame at a second end. The conditioning assembly is structurally configured to impact a side of a bulk bag positioned on the discharge support base, without impacting a bottom of a bulk bag, wherein the distal end of the first conditioner frame is directed at least partially in an upward direction within the bulk bag receiving region.
