Solution Overview

Problem

Conventional conveyor systems face challenges in allowing workers and vehicles to pass through due to fixed conveyor paths, requiring additional space and power for flip-up mechanisms, and existing extendable conveyor technologies lack a driving source for article transfer without manual intervention.

Innovation Solution

A path forming device with a fixed side conveyor and a movable side conveyor that combines lifting, lowering, and linear movement functions, allowing the movable conveyor to protrude and retract seamlessly, maintaining a constant conveying surface height and enabling passage for workers and vehicles without additional space or power requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a fixed conveyor device is used to maintain constant height position, then conveying surface stability is improved, but the ability to form passages for workers and vehicles deteriorates

Engineering Contradiction:
Improveconveying surface stabilityVSAvoidpassage formation capability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The conveyor device transitions from a fixed structure to a dynamic one with lifting and lowering functions. The movable side conveyor device can change its vertical position to either align with the fixed side conveyor device for article conveying or lower to form passages, thus resolving the contradiction between stability and adaptability

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The conveyor device is divided into a fixed side conveyor device and a movable side conveyor device. The movable side can be lifted and lowered independently to create passages while the fixed side maintains constant height, allowing the system to simultaneously maintain stability in one segment while providing adaptability in another

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If a flip-up conveyor device is used to enable passage, then passage formation capability is improved, but space requirements and power consumption deteriorate

Engineering Contradiction:
Improvepassage formation capabilityVSAvoidspace above conveyor device
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

Instead of moving the conveyor device vertically in a flip-up manner that requires space above, the movable side conveyor device moves horizontally along the linear movement function to form passages. This dimensional change eliminates the need for vertical clearance space while maintaining passage formation capability

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

Solution Approach 2:

The conveyor device uses a dynamic linear movement mechanism instead of a static flip-up structure. The movable side conveyor device can extend and retract along the linear movement function, enabling passage formation without requiring fixed space above the conveyor device

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If a flip-up conveyor device is used to enable passage, then passage formation capability is improved, but power requirements deteriorate

Engineering Contradiction:
Improvepassage formation capabilityVSAvoidpower for operating mechanism
Core Design Contradiction:
Adaptability or versatilityVSPower

Solution Approach 1:

The conveyor device uses dynamic lifting and lowering functions with smaller power requirements compared to flip-up mechanisms. The movable side conveyor device is lifted and lowered only when needed for passage formation, rather than requiring continuous power to maintain a flip-up position, thus reducing overall power consumption

Inventive Principle:
Principle #15Dynamics

4Adaptability or versatility

If an extendable conveyor device is used to form passages, then passage formation capability is improved, but article transfer capability without manual intervention deteriorates

Engineering Contradiction:
Improvepassage formation capabilityVSAvoidarticle transfer automation
Core Design Contradiction:
Adaptability or versatilityVSExtent of automation

Solution Approach 1:

The conveyor device maintains automation by using dynamic lifting and lowering functions that can automatically adjust the movable side conveyor device to the correct height for article transfer. The system can automatically extend and retract the movable side conveyor device along the linear movement function, enabling both passage formation and automated article transfer without manual intervention

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The conveyor device performs self-adjustment through its lifting and lowering functions, automatically positioning the movable side conveyor device for either article conveying or passage formation based on operational needs, eliminating the need for manual intervention in the article transfer process

Inventive Principle:
Principle #25Self-service
