Solution Overview
Problem
There is a need for travel items such as packing bags and tables that can fold compactly for storage and expand easily for use, similar to tents, to accommodate decreasing space constraints.
Innovation Solution
A compartmentalized folding bag with a spine mechanism that allows it to expand and compress radially, and a collapsible folding table with compressible sections and flexible legs that can be compactly stored and easily set up, using a telescopic and spring-based mechanism for efficient folding and unfolding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the bag and table are designed to fold compactly for storage, then the storage volume is reduced, but the ease of expansion and setup time may be worsened
Solution Approach 1:
The patent applies nesting by placing hollow cylindrical sections inside one another during folded storage. The compressible hollow sections are arranged in a nested configuration where smaller sections fit within larger ones, achieving maximum compactness. During expansion, these nested sections slide outward along guide surfaces to form the expanded structure, ensuring both compact storage and ease of deployment.
Solution Approach 2:
The patent employs dynamic mechanisms including spring-loaded sections that automatically expand when released, and telescopic legs with cam-locked positioning. The spine mechanism uses spring-loaded cylinders that push sections outward during expansion, while the legs incorporate cam surfaces that automatically lock into position, reducing manual effort and setup time while maintaining compact folded dimensions.
2Ease of operation
If the bag uses a complex spine mechanism for radial expansion, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent implements self-service through spring-loaded sections that automatically expand and lock into position without manual intervention. The cam-locked legs automatically engage and disengage based on their position in the expansion cycle, and the hollow sections use spring mechanisms to self-propel outward during deployment, reducing the need for complex manual operation mechanisms.
Solution Approach 2:
The patent divides the bag structure into multiple independent compressible hollow sections that can expand and contract independently. Each section contains its own spring mechanism and locking features, allowing modular operation. This segmentation simplifies the overall control mechanism while enabling complex radial expansion through coordinated independent section deployment.
3Volume of moving object
If the table uses telescopic legs with rotation compartments, then the compact storage is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple functions into the leg structure: the telescopic legs provide height adjustment, the cam-locked mechanism provides stable positioning, and the integrated rotation compartments serve dual purposes as both storage spaces for accessories and structural elements that guide leg rotation during folding. This consolidation reduces the number of separate components while achieving compact storage.
Solution Approach 2:
The patent applies nesting by placing rotation compartments within the leg structure, where smaller storage compartments are positioned inside the hollow leg sections. This allows the legs to maintain their telescopic functionality while incorporating additional storage and rotation capabilities without significantly increasing external dimensions, achieving compact storage with enhanced functionality.
