Removable Carry Bag Compression Layout for Packed Luggage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luggage designs lack a dual-purpose carrying bag that can function both as a compression member and a daily use bag, and existing strap connection points are not optimized for compression, potentially leading to damage from excessive loads.
Innovation Solution
A luggage system with a removable carry bag that can be used as a compression assembly, utilizing existing strap connection points designed to withstand body loads, and strategically placed anchors within the luggage to compress the bag even without internal objects, with compression straps engaging these anchors to cinch the bag against the luggage interior.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a removable carry bag is designed to serve as both a daily use bag and a compression member, then versatility is improved, but device complexity increases
Solution Approach 1:
The carry bag is designed with dual functionality: it serves as both a daily use bag and a compression member. The bag includes integrated compression straps with connectors that can engage with anchors on the luggage body, allowing the same bag structure to perform both carrying and compression functions without requiring separate components.
Solution Approach 2:
The compression straps are merged with the carry bag structure rather than being separate components. The compression straps are integrated into the bag's strap system, and the connectors are part of the bag's existing hardware, combining the compression function with the carrying function in a unified structure.
2Device complexity
If existing strap connection points are used for compression, then device complexity is reduced, but strength deteriorates due to excessive loads
Solution Approach 1:
The connection points on the carry bag are specifically designed and positioned to handle compression loads. The bag includes reinforced connection areas with dedicated anchors and strap attachment points that are optimized for compression forces, rather than using generic strap connection points. This localized reinforcement ensures sufficient strength at the critical compression interfaces.
3Adaptability or versatility
If compression straps are added to the carry bag, then compression function is improved, but device complexity increases
Solution Approach 1:
The compression straps serve dual purposes: they function as both carrying straps for the bag and as compression members when engaged with the luggage body anchors. The same strap system is used for both carrying the bag and compressing luggage contents, eliminating the need for separate compression straps and reducing overall system complexity.

AI summary
A luggage system (102) can include an outer luggage body (110) having a first luggage body portion (112), at least a first anchor (118) secured to the first luggage body portion, a carry bag (230), which can be in the form of a backpack or other wearable bag. The carry bag can include a main body portion with at least one interior compartment and a first shoulder strap (236) connected to the main body portion. A first compression strap (260) assembly can be configured to engage the main body portion and the first anchor and be configured to cinch the main body portion towards the first anchor.
