Solution Overview

Problem

There is a need for a single carrying device that can conveniently hold and allow operation of mobile communications devices, such as cell phones and PDAs, while also storing credit card-sized items like money and licenses, due to the increasing multifunctionality and compact size of these devices.

Innovation Solution

A customizable case with injection-molded rubber and a sewn leather pocket that securely holds the device and credit card-sized items, providing access to all interfaces and controls, allowing operation of the device while stored, using an adhesive to attach the pocket to the case.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a single pocket case is designed to hold both mobile communications device and credit card sized items, then carrying convenience is improved, but device complexity increases

Engineering Contradiction:

Improvecarrying convenienceVSAvoidcase structure complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the mobile device case and credit card holder into a single integrated unit. The credit card holder is adhered directly to the case, creating one unified carrying device that consolidates multiple functions (device protection + card storage) into a single structure, eliminating the need to carry separate items.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The case is designed to serve multiple purposes: it protects the mobile communications device while simultaneously functioning as a holder for credit cards, driver licenses, and other card-sized items. This multi-functional design allows one object to replace what would traditionally require multiple separate carrying items.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Quantity of substance

If the case is designed with pockets and compartments for additional items, then storage capability is improved, but ease of operation deteriorates due to potential bulk addition

Engineering Contradiction:

Improvestorage capacityVSAvoiddevice operability

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The credit card holder is positioned specifically on the back or side portions of the case, utilizing spaces that would otherwise be unused. This localized placement adds storage functionality without interfering with the front-facing controls, display, or primary operational areas of the mobile device.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The credit card holder is adhered to the case in a nested configuration where the holder integrates into the overall case structure. The holder fits within the contours of the case design, allowing the additional storage function to be embedded within the existing form factor without substantially increasing external dimensions.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

A form-fitting case is comprised of two major components: 1) a structure for carrying mobile communications devices, and 2) a pocket for carrying of credit card sized devices. The pocket may be fabricated of fabric or leather. The pocket and structure are permanently adhered to create a single carrying case for both mobile communications devices such as cell phones and for items such as credit cards or paper money.
