Reconfigurable Storage Device Strap Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage devices, such as bags and briefcases, lack reconfiguration capabilities to allow for varied carrying methods, limiting user flexibility in how they can be worn or carried.
Innovation Solution
A storage device with a pivotally coupled body and a strap that can be configured between a shoulder-wearable and backpack-style configuration, utilizing releasable strap segments and securing devices to form loops for arm reception, enabling versatile carrying options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a storage device uses a fixed strap configuration, then the structure is simple and easy to manufacture, but the device lacks versatility in carrying options
Solution Approach 1:
The strap is divided into multiple detachable segments (first strap segment and second strap segment) that can be separated and reconnected in different configurations. This segmentation allows the strap to transform from a single fixed structure into a multi-configurable system, enabling both shoulder carry and backpack styles while maintaining relatively simple individual segment structures
Solution Approach 2:
The strap configuration is made dynamic through releasable coupling mechanisms that allow users to switch between different strap arrangements. The coupling devices enable the strap to transition between a continuous single-strap configuration and a split dual-loop configuration, providing adaptability without requiring multiple separate strap components
2Adaptability or versatility
If a storage device uses a single continuous strap, then the structure is simple, but it cannot provide backpack-style carrying with separate loops for each arm
Solution Approach 1:
The coupling devices are pre-positioned at specific locations on the strap segments and body securing devices, allowing users to quickly reconfigure the strap without complex assembly steps. The releasable coupling mechanisms are designed to be intuitively operable, reducing the operational complexity of switching between carrying styles
Solution Approach 2:
The same coupling devices serve multiple functions: they can connect strap segments to each other to form a continuous strap, or connect strap segments to body securing devices to form separate loops. This multi-functionality eliminates the need for different coupling mechanisms for different configurations, maintaining ease of operation while providing versatility
3Adaptability or versatility
If a storage device includes multiple detachable strap segments with coupling devices, then reconfiguration flexibility is improved, but the device complexity increases
Solution Approach 1:
The coupling devices are designed to be substantially identical or similar in structure and function, allowing for standardized manufacturing processes. This homogeneity means that the same coupling device design can be used throughout the product, simplifying production tooling and quality control while still enabling multiple strap configurations through their versatile connection capabilities

AI summary
A binder device including a body having a first cover and a second cover directly or indirectly pivotally coupled together and at least partially defining an inner compartment therebetween. The body further includes a binding mechanism positioned in the inner compartment, a first body securing device coupled to the body, and a second body securing device coupled to the body. The binder device includes a strap including first and second strap segments. The strap is movable between a first configuration wherein the first and second strap segments are releasably coupled together to form a continuous strap that is wearable over a shoulder of a user, and a second configuration wherein the first strap segment is releasably coupled the first body securing device and the second strap segment is releasably coupled to the second body securing device such that the first and second strap segments each at least partially defines a loop. Each loop is shaped and configured to receive an arm of a user therethrough such that the binder device is wearable on a back of the user in the manner of a backpack. Each strap segment is configured to be releasably coupled to only one of the first or second body securing devices.
