Clamshell Pack with Convex-Concave Sidewalls for Selective Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing backpacks for camera equipment require complete unzipping to access stored items, making retrieval and storage time-consuming.
Innovation Solution
A clamshell pack design featuring a rear portion with convex sidewalls and a front portion with complementary concave sidewalls, allowing for partial opening and easy access to the interior without fully unzipping, utilizing a coupling mechanism and control mechanism for adjustable access and secure storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pack uses a traditional zipped cover design, then the pack provides secure storage, but the pack requires complete unzipping to access stored items, making retrieval and storage time-consuming
Solution Approach 1:
The pack is divided into a front portion and a rear portion that can be separated relative to each other. The front portion can be opened independently to provide access to stored items without requiring the entire pack to be unzipped, enabling selective access to specific items while maintaining security of the remaining contents.
Solution Approach 2:
The pack incorporates a dynamic opening mechanism where the front portion can be moved between different positions (open and closed configurations). This allows the pack to transition from a fully enclosed state to a partially open state, providing flexible access options that reduce the time required for item retrieval and storage.
2Loss of time
If the pack allows partial opening for easy access, then retrieval and storage time is reduced, but the structural integrity and secure storage may be compromised
Solution Approach 1:
The pack is divided into a front portion and a rear portion that can be separated relative to each other. The front portion can be opened independently to provide access to stored items without requiring the entire pack to be unzipped, enabling selective access to specific items while maintaining security of the remaining contents.
Solution Approach 2:
The sidewalls feature asymmetric configurations where the front portion has concave sidewalls that complement the convex sidewalls of the rear portion. This asymmetric design allows the front portion to open independently while maintaining structural integrity and secure closure when closed.

AI summary
A pack enables objects stored therein to be accessed easily and efficiently. The pack includes a rear portion including one or more first sidewalls, and a front portion including one or more second sidewalls. Each first sidewall has a generally convex configuration, and each second sidewall has a generally concave configuration that complements the convex configuration of the first sidewalls. The second sidewalls are extendable generally along the first sidewalls to couple the front portion to the rear portion.
