Collapsible Bicycle Travel Case With Folding Base Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Travel cases for large objects, such as bicycles, are often cumbersome and difficult to maneuver in crowded spaces, and when too large for storage, they occupy significant space in living areas.
Innovation Solution
A collapsible case design featuring a base with movable base portions and a frame assembly that can be folded and extended, allowing for compact storage and expanded use, with features like zippers, hinges, and locking fasteners to secure the configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a large travel case is used to accommodate bicycles or other large objects, then the case can store and protect these items, but the case becomes cumbersome and difficult to maneuver in crowded spaces
Solution Approach 1:
The base is designed with movable portions that can transition between extended and retracted positions, allowing the case to dynamically adjust its size. The base portions can be moved relative to each other along the longitudinal axis, enabling the case to expand for storage and contract for transport, directly resolving the contradiction between volume and maneuverability
Solution Approach 2:
The base is divided into multiple movable portions (first base portion and second base portion) that can independently move relative to each other. This segmentation allows the case to be divided into functional segments that can be adjusted independently, enabling compact configuration for easy maneuvering while maintaining full volume when needed for storage
2Volume of moving object
If a large travel case is used to store bicycles or other large objects, then the case provides adequate storage space, but the case occupies significant space in living areas when not in use
Solution Approach 1:
The case incorporates a dynamic base structure that can transition between extended and retracted positions. When not in use, the base portions are retracted to minimize the case's footprint in living areas. When storage is needed, the base portions are extended to provide adequate volume for bicycles and other large objects, thus resolving the contradiction between storage volume and storage space occupation
Solution Approach 2:
The movable base portions can be nested or folded into each other when retracted, allowing the case to occupy minimal space in living areas. The frame assembly also includes collapsible portions that can be stored within the case body, creating a nested configuration that minimizes the overall footprint when the case is not in use
3Volume of moving object
If the base is extended to provide adequate storage space, then large objects can be stored, but the base becomes more complex to operate
Solution Approach 1:
The locking mechanism is integrated directly into the frame assembly, combining the base extension and locking functions into a unified structure. The locking portion of the frame assembly interacts with the movable base portions to provide automatic locking when the base is extended, eliminating the need for separate locking devices and reducing operational complexity despite the extended functionality
