Collapsible Luggage Foldable Support Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional collapsible luggage with telescopic rods face issues where the reinforcing unit's board portions easily fold due to lack of support, leading to instability and collapse of the flexible body when expanded.
Innovation Solution
The collapsible luggage incorporates a foldable support system with a first and second support member, a resilient buckle member, and a protrusion, allowing the foldable support to pivot between unfolded and folded states, maintaining stability and preventing easy collapse of the flexible body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the telescopic rod is in the extended position and the flexible body is expanded, then the luggage provides adequate carrying space, but the board portions of the reinforcing unit are easily folded due to lack of support
Solution Approach 1:
The foldable support is divided into two separate support members (first support member and second support member) that can independently pivot and provide localized support to the flexible body, preventing the board portions from folding while maintaining expansion capability
Solution Approach 2:
The support members are designed to be pivotable between extended and folded positions, allowing the support structure to dynamically adapt - providing support when expanded and being compact when collapsed, thus resolving the stability issue without sacrificing volume efficiency
2Stability of the object's composition
If a foldable support system is added to maintain stability, then the structural integrity is improved, but the device complexity increases
Solution Approach 1:
The foldable support members are integrated with the existing telescopic rod unit and reinforcing unit structures, sharing common mounting points and spatial arrangements, thus providing enhanced support without proportionally increasing overall device complexity
Solution Approach 2:
Instead of making the entire reinforcing unit rigid to prevent folding, the invention uses pivotable support members that allow controlled movement - inverting the approach from rigid prevention to flexible control, thereby maintaining simplicity while achieving stability
3Stability of the object's composition
If the foldable support is in the unfolded state, then the flexible body is supported and maintained in expanded state, but the buckles member and protrusion structure adds to the device complexity
Solution Approach 1:
The buckle member and protrusion form a self-locking mechanism where the protrusion automatically engages with the buckle member when the support is in the unfolded state, maintaining the expanded position without requiring additional active locking components or complex control systems
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The foldable support system effectively maintains the luggage in an expanded state without collapsing and allows for easy conversion to a collapsed state, optimizing storage space while ensuring structural integrity and ease of use.
Implementation Method 1
the buckle member is urged to deform resiliently so that the protrusion is permitted to pass over the buckle member

AI summary
A collapsible luggage includes a base, a flexible body connected to the base, a telescopic rod unit coupled to the flexible body, and a foldable support coupled to the flexible body, disposed opposite to the telescopic rod unit, and including a first support member that has a buckle member, and a second support member that has a protrusion. When the foldable support is in an unfolded state, the buckle member partially overlaps the protrusion to maintain the foldable support in the unfolded state. When a force is applied to move the foldable support from the unfolded state to the folded state against a resilient force of the buckle member, the buckle member is urged to deform resiliently so the protrusion is permitted to pass over the buckle member.
