Friction Fit Handbag Accessory with Dual Compartments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rubber handbag or carrying case accessories are limited to single-use, single-retaining compartments and require additional hardware for installation, which restricts their multipurpose functionality and ease of use.
Innovation Solution
A rubber handbag or carrying case accessory with a friction fit design that attaches over the top rim, featuring two retaining compartments for secure storage of multiple items, including electronic devices, beverages, and pre-packaged foods, without the need for additional hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If snap fasteners or button style devices are used for installation, then the accessory can be securely attached, but additional hardware is required which increases device complexity and installation difficulty
Solution Approach 1:
The patent removes snap fasteners, buttons, and other traditional fastening hardware from the accessory design. The attachment mechanism relies solely on the friction fit between the accessory body and the bag rim, extracting unnecessary components to simplify the overall device while maintaining secure attachment through properly engineered contact surfaces and friction characteristics.
Solution Approach 2:
The accessory utilizes the bag rim itself as the attachment mechanism through friction fit. The rim's geometry and material properties provide the necessary retention force, eliminating the need for separate fastening components. The system serves itself by using the bag's existing structure as part of the attachment solution.
2Adaptability or versatility
If single retaining compartment design is used, then the accessory structure is simpler, but multipurpose functionality is limited
Solution Approach 1:
The accessory body is divided into multiple retaining compartments separated by internal walls. This segmentation allows different items to be stored in distinct sections, enabling multipurpose functionality while maintaining a unified attachment mechanism. The compartments can be configured in various arrangements to suit different storage needs.
Solution Approach 2:
The accessory is designed with multiple retaining compartments that can accommodate various types of items including electronics, beverages, and packaged foods. The universal design allows a single accessory to serve multiple storage functions, replacing the need for multiple separate accessories.
3Ease of operation
If friction fit design is used, then ease of operation is improved with easy installation and removal, but attachment security may be compromised
Solution Approach 1:
The friction fit mechanism is optimized by carefully controlling parameters such as the contact surface area, rim geometry, material coefficients of friction, and compression force. These parameters are engineered to provide sufficient attachment security while allowing easy manual installation and removal. The balance between retention force and ease of operation is achieved through precise parameter selection.
Solution Approach 2:
The friction fit interface utilizes curved surfaces and rounded geometries that distribute contact forces evenly, increasing the effective contact area and frictional engagement. The curved profile of the rim and corresponding recess in the accessory body creates a mechanical interlock effect that enhances security while maintaining ease of attachment.
