Solution Overview

Problem

The challenge of manually lifting heavy suitcases into elevated compartments such as car trunks or train compartments is difficult for many individuals, particularly the elderly or those with physical limitations, necessitating additional effort or assistance, and existing luggage solutions fail to address this issue effectively.

Innovation Solution

A motorized self-lifting suitcase (MSLS) with a telescopic rod mechanism powered by a motor, activated by a button, elevates the suitcase to approximately 30 inches, allowing easy loading into elevated spaces without manual effort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a motorized self-lifting mechanism is added to the suitcase, then the ease of operation is improved, but the device complexity increases

Engineering Contradiction:

Improveease of loadingVSAvoidmechanism complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The suitcase performs the lifting action automatically through a motorized mechanism that extends a telescopic rod to elevate the suitcase body into the trunk, eliminating the need for manual lifting by the user. The system serves itself by incorporating the lifting function directly into the suitcase structure.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The lifting mechanism is divided into modular components including a motor assembly, a telescopic rod with multiple extendable sections, and a control system. This segmentation allows the complex lifting function to be achieved through coordinated operation of simpler, independent parts that can be manufactured and assembled separately.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If a telescopic rod mechanism is incorporated to elevate the suitcase, then the lifting capability is improved, but the volume of the suitcase increases

Engineering Contradiction:

Improvelifting capabilityVSAvoidsuitcase volume

Core Design Contradiction:

Ease of operationVSVolume of moving object

Solution Approach 1:

The telescopic rod employs a nested structure where multiple rod sections are housed within each other in a collapsed state. When the lifting mechanism is activated, these nested sections extend sequentially to achieve the full lifting height. This nesting approach allows the mechanism to provide substantial lifting capability while occupying minimal space within the suitcase when not in use.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Ease of operation

If a motorized lifting system is integrated into the suitcase, then the ease of operation is improved, but the weight of the suitcase increases

Engineering Contradiction:

Improveease of loadingVSAvoidsuitcase weight

Core Design Contradiction:

Ease of operationVSWeight of moving object

Solution Approach 1:

The traditional manual mechanical lifting approach is replaced with an electromechanical system. A compact motor provides the lifting force through a gear mechanism that drives the telescopic rod extension. This substitution allows for more efficient force application and better control compared to purely mechanical spring or lever systems, while the motor and control electronics occupy less space and weigh less than equivalent mechanical lifting components.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A Motorized Self-Lifting Suitcase (MSLS) system-addresses the common difficulty of loading heavy luggage into elevated compartments, such as car trunks and train storage spaces designed to fit within standard cabin baggage dimensions. The MSLA system features a suitcase body with a telescopic lift rod powered by a motor and a battery. When the user activates the suitcase body by pressing a button switch, the motor engages a gear mechanism that lowers the telescopic lift rod, raising the suitcase body to the desired height. An integrated hourglass spring assists in the smooth extension of a telescopic part, ensuring stability during operation. After loading is complete, the telescopic lift rod can be manually retracted and securely locked in place with a snap lock mechanism, promoting portability and convenience.
