Solution Overview

Problem

Existing sorting conveyors face limitations in stability and cargo handling due to unsupported intermediate covers and excessive relative movement between load-bearing elements, leading to instability and risk of cargo items getting trapped.

Innovation Solution

The intermediate cover is attached to a guide unit that moves relative to the load-bearing elements, providing increased stability and reduced relative rotation, with a flexible cover element supported by a base plate and receiving slots, ensuring complete coverage even in curves.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the intermediate cover is fastened to a load bearing element, then the intermediate cover is supported from below, but the load-bearing capacity remains limited due to the cantilevered end configuration

Engineering Contradiction:
Improveload-bearing capacityVSAvoidstability of intermediate cover
Core Design Contradiction:
StrengthVSStability of the object's composition

Solution Approach 1:

A guide unit is introduced as an intermediary component between the intermediate cover and the load bearing elements. The guide unit includes a guide plate that extends into the intermediate space and provides a stable mounting surface for the intermediate cover, thereby increasing its load-bearing capacity and stability without directly attaching it to the load bearing elements.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The intermediate cover is repositioned from being attached to the lateral sides of load bearing elements to being mounted on a guide unit that extends into the intermediate space. This spatial reconfiguration provides additional support structure and increases the effective load-bearing area of the intermediate cover.

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

2Reliability

If the intermediate cover is fixed to a load bearing element, then coverage is provided, but the relative movement between the intermediate cover and adjacent load-carrying element is large when cornering, causing cargo items to get trapped

Engineering Contradiction:
Improverisk of cargo entrapmentVSAvoidrelative movement during cornering
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The intermediate cover is made movable relative to the guide unit through a coupling mechanism that allows rotation and adjustment. This dynamic configuration enables the intermediate cover to adapt its position during cornering maneuvers, reducing relative movement with adjacent load-carrying elements and preventing cargo entrapment while maintaining reliable coverage.

Inventive Principle:
Principle #15Dynamics

3Reliability

If the cover element is made flexible to accommodate curves, then complete coverage is maintained during turns, but the structural stability may be compromised

Engineering Contradiction:
Improvecomplete coverage during curvesVSAvoidstructural stability
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

The intermediate cover incorporates a flexible cover element that can bend and deform to maintain contact with adjacent load-carrying elements during cornering and curved path operations. This flexibility ensures complete coverage and prevents cargo entrapment while the overall structure remains stable due to the rigid guide unit mounting.

Inventive Principle:
Principle #30Flexible shells and thin films
