Solution Overview

Problem

Existing transfer devices experience poor stability during material conveying due to tilting and vibration of the loading platform when lifting heavier materials, primarily caused by off-center loading and the use of pneumatic or hydraulic cylinders.

Innovation Solution

A transfer device with a support frame, loading platform, and limiting assemblies that include sleeves and slide rails to constrain the movement of the loading platform, ensuring multi-point limitation and preventing tilting and vibration during lifting and lowering processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If pneumatic or hydraulic cylinders are used to drive the loading platform, then the lifting operation of materials can be achieved, but tilting and vibration or even overturning of the loading platform may occur during the lifting of heavier materials

Engineering Contradiction:
Improvelifting capabilityVSAvoidloading platform stability
Core Design Contradiction:
PowerVSStability of the object's composition

Solution Approach 1:

The lifting system is segmented into multiple independent lifting points (at least two lifting members) distributed across the loading platform. This segmentation allows for balanced force distribution and prevents tilting by ensuring that the platform is supported at multiple locations simultaneously, rather than relying on a single centralized lifting point.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a horizontal constraint dimension by incorporating limiting assemblies (sleeves and limit posts) that restrict the loading platform's movement to a predetermined path. This adds a spatial dimension of control, preventing the platform from deviating horizontally during lifting, thereby eliminating tilting and vibration caused by off-center loading.

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

2Adaptability or versatility

If materials are not positioned at the center of the loading platform, then loading flexibility is improved, but tilting and vibration may occur during lifting

Engineering Contradiction:
Improvematerial positioning flexibilityVSAvoidloading platform stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The limiting assemblies (sleeves sliding on limit posts) introduce a constrained movement path that allows the loading platform to move horizontally along a predetermined trajectory while preventing tilting and rotation. This enables materials to be loaded at various positions on the platform without compromising stability, as the limiting mechanism compensates for off-center loading by guiding the platform's movement.

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

Solution Approach 2:

The limiting assemblies act as intermediary elements between the loading platform and the support frame. These intermediaries (sleeves and limit posts) mediate the interaction by allowing controlled horizontal movement while preventing unwanted tilting and vibration, thus enabling flexible material positioning without stability loss.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If the loading platform is allowed to move freely during lifting, then ease of operation is improved, but stability and precision of material conveying deteriorate

Engineering Contradiction:
Improveplatform movement freedomVSAvoidmaterial conveying precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The limiting assemblies constrain the loading platform's movement to a predetermined horizontal path while allowing vertical lifting motion. This selective constraint maintains ease of operation by permitting necessary movements (vertical lifting and limited horizontal travel) while preventing unwanted movements (tilting, rotation, and off-path deviation), thereby ensuring precise material conveying.

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

AI summary

A transfer device (100) comprises a support frame (10), a loading platform (20), a first limiting assembly (30), a second limiting assembly (40), and a lifting member (50). The loading platform (20) comprises a base plate (21), a support plate (22), a material belt (2), and a driving member (24). The first limiting assembly (30) comprises a sleeve (31) fixedly arranged on the base plate (21) and a limit post (32) extending through the sleeve (31). The second limiting assembly (40) comprises a slide rail (41) and a slider (42) slidably arranged on the slide rail (41). The slide rail (41) is parallel to the limit post (32). The lifting member (50) drives the loading platform (20) to move relative to the support frame (10). By the cooperation of the first limiting assembly (30) and the second limiting assembly (40), two different position-limiting structures simultaneously act on the loading platform (20) and thus achieve a multi-point limitation, preventing the loading platform (20) from tilting and vibrating during the lifting and lowering processes and ensuring conveying stability during the lifting of materials.
