Solution Overview

Problem

Existing self-movement devices for wheel-equipped apparatuses are difficult to install, costly, and limited to moving one apparatus at a time, without the ability to transport people and items simultaneously.

Innovation Solution

A modular and configurable device for self-movement of wheel-equipped apparatuses that can be easily installed by an untrained user, utilizing low-cost sensors and allowing for simultaneous movement of multiple apparatuses through train-type and tandem-type operating configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If existing self-movement devices are used, then autonomous movement is achieved, but installation difficulty increases and costs rise

Engineering Contradiction:
Improveautonomous movementVSAvoidinstallation complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The device is divided into separate functional modules: a control unit with processing circuitry, sensor units distributed at different locations, and communication units. These modular components can be independently installed and configured, reducing overall installation complexity while maintaining autonomous movement capability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The control unit serves multiple functions by integrating processing circuitry that can perform navigation, obstacle detection coordination, and control signal generation. This multi-functional approach reduces the number of separate components needed, simplifying installation while achieving autonomous operation

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

2Extent of automation

If existing self-movement devices are used, then autonomous movement is achieved, but device cost increases

Engineering Contradiction:
Improveautonomous movementVSAvoidmanufacturing cost
Core Design Contradiction:
Extent of automationVSEase of manufacture

Solution Approach 1:

The patent employs cost-effective sensor units and communication units that can be manufactured at lower costs compared to integrated expensive systems. These units can be produced using standard manufacturing processes, reducing overall device cost while maintaining autonomous movement functionality

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

By segmenting the system into separate control unit, sensor units, and communication units, each component can be manufactured independently using optimized processes for that specific function, reducing overall manufacturing costs compared to producing a single complex integrated system

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If existing self-movement devices are used, then single apparatus movement is enabled, but versatility decreases

Engineering Contradiction:
Improvemulti-apparatus movement capabilityVSAvoidsystem configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control unit is designed with universal control signals that can operate different types of wheel-equipped apparatuses (wheelchairs, stretchers, trolleys). The sensor units and communication units work together in a standardized configuration that adapts to multiple apparatus types, enabling versatile multi-apparatus movement without increasing system complexity

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

Solution Approach 2:

The system configuration is made dynamic and adaptable through wireless communication between control units and sensor units. The processing circuitry can dynamically adjust control parameters based on the specific apparatus being controlled, allowing the same device to efficiently manage multiple different apparatus types

Inventive Principle:
Principle #15Dynamics
