Carrying Case Rigid Flexible Compartment Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional carrying cases lack a combination of effective protection and accessibility, as they either rely solely on rigid materials for protection or flexible materials for comfort, failing to provide a balanced solution for storing and carrying sensitive items.
Innovation Solution
A backpack design incorporating a rigid first compartment with a movable shell structure for protection and a flexible second compartment, coupled with a support member and connecting members like frames, straps, and screws, allowing for both protection and ease of access while being wearable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a carrying case uses rigid materials for protection, then protection against water, impact, and dust is improved, but weight and comfort are worsened
Solution Approach 1:
The carrying case is divided into two distinct compartments: a rigid first compartment for protection-sensitive items and a flexible second compartment for other items. This segmentation allows each compartment to be optimized for its specific function, with the rigid compartment providing necessary protection without requiring the entire case to be heavy and rigid.
Solution Approach 2:
Different materials and structural properties are applied to different parts of the carrying case. The first compartment uses rigid materials with sealing mechanisms for maximum protection, while the second compartment uses flexible materials for comfort and adaptability. This local differentiation resolves the contradiction by providing protection only where absolutely necessary.
2Reliability
If a carrying case uses rigid materials for protection, then reliability is improved, but ease of operation is worsened
Solution Approach 1:
The case is segmented into two compartments with independent access mechanisms. The rigid first compartment has a shell member that moves relative to the main body to provide access, while the flexible second compartment can be accessed separately. This allows users to access frequently needed items in the flexible compartment without compromising the sealed protection of the rigid compartment.
Solution Approach 2:
The shell member of the rigid compartment is designed to move relative to the main body, providing dynamic access capability. This movement mechanism allows the rigid compartment to transition between a sealed protected state and an accessible state, resolving the contradiction between maintaining reliable protection and enabling ease of operation.
3Ease of operation
If a carrying case uses flexible materials for comfort, then ease of operation is improved, but protection against water, impact, and dust is worsened
Solution Approach 1:
The carrying case separates items requiring protection from items that do not, placing protected items in the rigid first compartment and other items in the flexible second compartment. This segmentation allows the flexible compartment to provide comfort and ease of operation for non-sensitive items while the rigid compartment maintains reliable protection for sensitive items.
4Adaptability or versatility
If a carrying case combines rigid and flexible compartments, then adaptability is improved, but device complexity is worsened
Solution Approach 1:
The case is divided into two main compartments with distinct structural characteristics. The first compartment has a rigid structure with a movable shell member, while the second compartment has a flexible structure. This clear segmentation simplifies the overall design by creating two self-contained functional units rather than attempting a complex hybrid structure.
Solution Approach 2:
The patent combines two traditionally separate carrying case designs (rigid and flexible) into a single integrated case. The rigid first compartment and flexible second compartment are coupled together to form one cohesive carrying case, providing the benefits of both types in a unified structure that does not significantly increase complexity.

AI summary
A carrying case includes a first compartment made of a rigid material, the first compartment defining an interior volume; and a second compartment coupled to the first compartment, the second compartment made of a flexible material, the second compartment defining an interior volume that is separate from the interior volume of the first compartment.
