Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional luggage solutions lack an efficient mechanism for transporting additional luggage items while maintaining ease of maneuverability and stability, especially over varying surfaces.
Innovation Solution
A suitcase with a wagon-style cart capability, equipped with telescopic handles, casters, and wheels, which forms a rolling structure that allows for the transport of additional luggage items by providing adjustable grips and load paths for smooth movement over supporting surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional luggage solutions are used, then the suitcase can store domestic articles, but it cannot efficiently transport additional luggage items
Solution Approach 1:
The suitcase is designed with a dual-function capability: it serves as both a conventional luggage storage container and a wagon-style cart for transporting additional luggage items. The exterior surface is configured to support additional luggage, and the telescopic handle with casters enables the suitcase to function as a pulling cart, allowing one piece of luggage to transport multiple pieces.
2Adaptability or versatility
If the suitcase is designed to transport additional luggage, then transport capability is improved, but maneuverability may deteriorate
Solution Approach 1:
The suitcase employs a telescopic handle that can be extended or retracted based on the user's needs. When transporting additional luggage, the handle extends to provide proper pulling height. The casters are designed to rotate and adapt to different surfaces, enabling smooth maneuverability whether the suitcase is being pulled as a cart or maneuvered in tight spaces.
Solution Approach 2:
The casters are configured to change their operational parameters based on the surface they encounter, allowing the suitcase to maintain stability and ease of movement across varying terrains. The handle height can be adjusted to match different user heights and loading configurations, optimizing maneuverability for each situation.
3Quantity of substance
If the suitcase supports additional luggage on its exterior surface, then load capacity is improved, but stability may worsen
Solution Approach 1:
The exterior surface of the suitcase is specifically designed with certain local characteristics that enable it to support additional luggage items. The surface geometry and attachment points are configured to distribute the weight of additional luggage evenly, maintaining the center of gravity and preventing tipping or instability during transport.
4Ease of operation
If telescopic handles and casters are added, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent combines the telescopic handle mechanism and the caster assembly into an integrated system that is attached to the suitcase body. Rather than adding separate independent components, the handle and casters are merged into a unified structure that works together, reducing the overall complexity compared to adding multiple separate systems. The attachment mechanism consolidates the connection points and structural requirements.
