Solution Overview

Problem

Traditional conveyor systems are not adjustable in height, making it difficult and costly to deposit items into containers or packages of varying heights, requiring modification or the use of multiple systems.

Innovation Solution

An adjustable conveyor system with a lift mechanism, supported by a computing device and sensors, allows the conveyor end to change height and align with different container openings, using a hinged joint, guide rails, and a lift system such as a crank or pulley system, enabling efficient item transfer into structures of varying heights.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a traditional fixed-height conveyor system is used, then the system structure is simple and cost-effective, but it cannot accommodate containers of varying heights

Engineering Contradiction:
Improveaccommodation of varying container heightsVSAvoidconveyor system structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The conveyor system incorporates a lift mechanism that enables the conveyor end to dynamically adjust its height position. The lift system, driven by a motor and transmission components, allows the conveyor to transition between multiple height positions to match different container openings, transforming a static system into an adaptive one that resolves the contradiction between structural simplicity and height versatility.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The adjustable conveyor system serves multiple functions: it can handle containers of various heights, adjust to different loading positions, and maintain operational flexibility. By integrating the lift mechanism, a single conveyor system replaces what would otherwise require multiple fixed conveyor systems, achieving multi-functionality that accommodates diverse container specifications.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple conveyor systems are used to handle different container heights, then adaptability improves, but system complexity and cost increase

Engineering Contradiction:
Improvehandling of different container sizesVSAvoidnumber of conveyor systems
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The invention merges the functions of multiple fixed conveyor systems into a single adjustable conveyor system. By combining the conveyor mechanism with an integrated lift system, it consolidates what would require separate conveyor units for different height requirements into one versatile platform, reducing overall system complexity while maintaining adaptability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

A single conveyor system is designed to perform the function of multiple conveyors by incorporating height adjustment capability. The lift mechanism enables one conveyor to serve multiple height positions, making it a universal solution that replaces several specialized conveyor systems and reduces operational complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If the conveyor height is adjusted frequently, then adaptability to different containers improves, but time consumption increases

Engineering Contradiction:
Improveadjustment to different container heightsVSAvoidtime for height adjustment
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The lift mechanism is designed to enable rapid, periodic height adjustments between predetermined positions. The motor-driven lift system can quickly transition the conveyor between common height levels, allowing frequent adaptation to different container types without significant time loss, as adjustments follow standardized motion cycles.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system enables quick changes in the vertical position parameter of the conveyor through the lift mechanism. By pre-programming common height positions and using a responsive lift system, the conveyor can rapidly alter its elevation parameter to match different container openings, minimizing adjustment time while maintaining high adaptability.

Inventive Principle:
Principle #35Parameter changes

AI summary

Systems, methods, and computer-readable media are disclosed for systems and methods for an adjustable conveyer system. The adjustable system may include one or more conveyor systems, a support structure for a first end of the conveyor system, a support structure for the second end of the conveyor system, and a lift system. The lift system may be actuated to cause the first end of the conveyor system to raise to a height that is higher or lower than the second end of the conveyor system. The adjustable system may be used to distribute packages to containers of various heights and sizes. In one example, the lift system may include a crank shaft. In another example, the lift system may involve a pulley system.
