Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional protective cases for personal electronic devices lack the ability to securely store and protect various items like cash, keys, and cards while providing protection against damage and theft, and they do not efficiently manage interchangeable accessories.
Innovation Solution
A modular protective case system that includes a sliding drawer and modular accessories with electrical connectivity, allowing for secure storage of items and easy access to cards and SIM cards, along with the ability to attach modular accessories for enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional protective case is used, then the device is protected from damage, but the case cannot securely store and protect various items like cash, keys, and cards
Solution Approach 1:
The patent implements a sliding drawer mechanism nested within the protective case body. The drawer can be inserted into and removed from the case, creating a nested structure that provides additional storage compartments for cards, cash, and keys without significantly increasing the overall case volume or complexity.
Solution Approach 2:
The case is segmented into multiple functional zones: a main compartment for the electronic device, a sliding drawer with multiple card slots, and additional storage areas. This segmentation allows the case to serve multiple purposes (device protection, card storage, cash storage, key storage) while maintaining a relatively simple overall structure.
2Ease of operation
If the device is removed from the case to access cards or SIM cards, then access is possible, but security and protection are compromised
Solution Approach 1:
The patent extracts the card storage and SIM card access functions from the main device compartment and places them in a separate sliding drawer. This allows users to access cards and SIM cards without removing the device from its protective compartment, thereby maintaining device security while providing easy access to cards through the drawer mechanism.
Solution Approach 2:
The sliding drawer acts as an intermediary structure between the user and the device. It provides a separate access path for cards and SIM cards, mediating the need for frequent card access without compromising the security of the main device compartment. The drawer can be opened independently while the device remains securely enclosed.
3Adaptability or versatility
If fixed accessories are integrated into the case, then functionality is enhanced, but adaptability to different needs is reduced
Solution Approach 1:
The patent implements a dynamic accessory system where the sliding drawer and its contents can be removed, replaced, or reconfigured based on user needs. The drawer structure allows for flexible arrangement of card slots and storage compartments, enabling the case to adapt to different storage requirements while maintaining a relatively simple base design.
Solution Approach 2:
The sliding drawer is designed as a universal component that can serve multiple functions: storing business cards, credit cards, cash, keys, and SIM cards. The modular design allows the same drawer structure to be configured for different storage needs, providing versatility without requiring multiple specialized cases or complex integrated features.

AI summary
An electrical accessory for use with a portable electronic device and with a protective cover for the portable electronic device is provided. The electrical accessory includes a body, an electrical connector, and electrical circuitry. The body includes a back portion and a bottom portion. The back portion is slidably attachable to the back of the protective cover to removably affix the electrical accessory to the back of the protective cover. The bottom portion is adapted to be proximate the bottom of the protective cover when the electrical accessory is removably affixed to the protective cover. The electrical connector is affixed to the bottom portion of the body of the electrical accessory. The electrical connector is positioned to electrically interconnect to an electrical port of the portable electronic device when the electrical accessory is affixed to the protective cover and when the portable electronic device is installed in the protective cover.
