Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing attachment accessories are limited in accommodating items of different shapes and sizes, lack storage capabilities, and do not provide discreet and secure storage with easy access, especially for tools and related items.
Innovation Solution
A multi-purpose attachment accessory with a base member and cap member that form a storage compartment and accessory compartment, featuring engagement members for secure locking and a flexible design allowing items of various shapes to be stored and accessed easily, using a retractable leash or string for user attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a chain is used to couple the small item to the user's pants, then the small item remains in the user's possession at all times, but the chain is long, heavy and exposed which is undesirable
Solution Approach 1:
The attachment accessory is nested within a pocket-friendly housing that contains both the attachment means and storage compartment. The entire assembly fits discreetly within a user's pocket while maintaining the coupling function, eliminating the need for exposed chains.
2Ease of operation
If a retractable device with attachment means is used, then the user can discreetly store and access the small item, but the attachment means are limited to fit only items with specific cross-sectional areas
Solution Approach 1:
The attachment means is designed with a universal attachment surface that can accommodate items of various shapes and sizes. The flat surface with multiple engagement features allows different item configurations to be securely attached, making the device versatile for multiple uses.
Solution Approach 2:
The attachment means is divided into multiple engagement features (protrusions and recesses) that can independently accommodate different item geometries. This segmentation allows the same attachment surface to securely hold various shapes through selective engagement of different features.
3Ease of operation
If a retractable device with attachment means is used, then the user can discreetly store the small item, but the attachment means lack storage means for other loose items
Solution Approach 1:
The invention merges the attachment means function with a storage compartment into a single integrated device. The housing contains both the retractable attachment mechanism and an enclosed storage space, allowing the user to carry both attached items and loose items simultaneously.
4Productivity
If multiple items are stored together, then the user has quick access to related items, but the items do not necessarily require to be stored in the user's pocket
Solution Approach 1:
The storage compartment is segmented into distinct sections (first storage compartment for tools, second storage compartment for related items) that can be independently accessed. This segmentation allows quick retrieval of specific items without exposing the entire contents, maintaining discretion while improving access efficiency.

AI summary
An attachment accessory includes a storage compartment having a floor and at least one first wall extending upwardly from the floor to form a storage space. A first engagement member and first extension member having a first aperture extend from the at least one first wall. An accessory compartment is positioned next to the storage compartment and includes an opening. A cap member includes a ceiling and at least one second wall extending downwardly from the ceiling. A second engagement member and second extension member having a second aperture extend from the at least one second wall. The first and second extension members are attached together via the first and second apertures. The storage compartment and the cap member are configured to be lockingly coupled together to enclose the storage space when the first and second engagement members are engaged.
