Suitcase Detachable Sub-Package Assembly Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for assembling and disassembling sub-packages in suitcases are either inconvenient due to tight fitting, occupy space with magic glue or rivets, and lose adhesiveness over time, or fail to protect internal items during collisions.
Innovation Solution
A detachable assembly structure using a fixed member and a movable member with a through hole structure and T-shaped design, allowing for easy assembly and disassembly by rotating the movable member, which is connected via a traction member for efficient positioning and locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If tight fitting method is used to fix sub-packages, then the sub-package is firmly combined with the master package, but it is very inconvenient to disassemble and replace the sub-package
Solution Approach 1:
The fixing mechanism is divided into a fixed member attached to the master package and a movable member on the sub-package. This segmentation allows the sub-package to be firmly held when assembled while enabling easy disassembly by simply moving the movable member to disengage from the fixed member, resolving the contradiction between firm combination and convenient disassembly.
Solution Approach 2:
The movable member is designed to be movable relative to the sub-package, allowing it to transition between engaged and disengaged states. This dynamic design enables the sub-package to be firmly fixed during use while allowing quick and easy removal when needed, solving the contradiction between stability and ease of operation.
2Ease of operation
If magic glue or rivets are used to fix sub-packages, then the structure is relatively large for easy operation, but it will occupy space and be unsightly
Solution Approach 1:
The movable member is designed to be nested within or alongside the sub-package structure, and the fixed member is integrated into the master package. When assembled, these components occupy minimal space while providing effective fixing, resolving the contradiction between ease of operation and space occupation.
Solution Approach 2:
The fixing mechanism extracts only the essential components needed for attachment (fixed member and movable member) without adding bulky structures like traditional rivets or large glue applications. This minimalistic approach ensures easy operation while occupying minimal space within the suitcase.
3Volume of moving object
If hook and loop is used for fixing, then the structure is compact, but after long time use the whole adhesiveness will be reduced
Solution Approach 1:
The invention replaces the chemical adhesion mechanism of hook and loop fasteners with a mechanical interlocking system consisting of a fixed member and a movable member. This mechanical system maintains compact structure while providing reliable, durable fixing that does not degrade over time like adhesive-based solutions, resolving the contradiction between compactness and reliability.

AI summary
The present disclosure provides an assembly structure for a suitcase, which comprises a master package forming an accommodating cavity and a sub-package assembled in the accommodating cavity, wherein the sub-package and the master package are connected or detached through a fixed member and a movable member. In the above design, the user can easily connect or disassemble the sub-package and the master package by the cooperation of the fixed member and the movable member, thus avoiding the problem of tight or loose fitting that may occur in the traditional way. At the same time, the fixed members in different positions can allow the sub-package to be assembled relative to the position of the master package, which greatly improves the flexibility of use.
