Solution Overview

Problem

There is a need for a mobile phone case that allows one-hand operation, wireless charging, and car mounting while also providing a secure pocket for personal items like credit cards, identification, and money, without encumbrances such as bags or purses, and enhancing the grip and comfort of holding the phone.

Innovation Solution

An attachable and removable pouch is integrated into the mobile phone case, featuring a zipper closure, a strap for secure attachment, and optional extender straps for different sizes, allowing the pouch to hold personal items and support the phone in an upright position without interfering with wireless charging or car mounting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a pouch is added to the phone case to carry personal items, then the need for bags and purses is reduced, but the phone case becomes more complex and may interfere with wireless charging and car mounting

Engineering Contradiction:

Improvehands-free capabilityVSAvoidcase structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the pouch and phone case into a single integrated unit, where the pouch is attached to the back of the phone case. This merging eliminates the need for separate bags or purses while maintaining a unified structure that doesn't interfere with wireless charging or car mounting when the pouch is positioned correctly.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The phone case is designed to serve multiple functions: protecting the phone, carrying personal items in the pouch, and allowing wireless charging and car mounting. The pouch is positioned and designed to be removable or foldable, enabling it to adapt to different usage scenarios without permanently blocking essential functions.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a pouch is integrated into the phone case, then personal items can be carried securely, but one-hand operation becomes more difficult

Engineering Contradiction:

Improvepersonal item carryingVSAvoidone-hand operation

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The pouch is positioned at the back of the phone case, away from the front controls and display area. This local placement allows users to access the phone's front functions with one hand while the pouch remains in the background, not interfering with thumb or finger access to buttons and screen.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The pouch is designed with flexible attachment mechanisms (snaps, Velcro, or magnetic connectors) that allow it to be easily opened, closed, or removed. This dynamic design enables users to quickly access or secure personal items without requiring two hands, and to remove the pouch if one-hand operation becomes necessary.

Inventive Principle:

Principle #15Dynamics

3Quantity of substance

If the pouch is made larger to hold more items, then carrying capacity increases, but the phone case size increases and grip comfort decreases

Engineering Contradiction:

Improvepersonal item capacityVSAvoidgrip comfort

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The pouch is designed with a capacity that is sufficient for essential personal items (cards, cash, keys) but not excessively large. This partial capacity approach ensures the pouch holds necessary items while maintaining a compact size that doesn't significantly increase the overall phone case dimensions or compromise grip comfort.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The pouch utilizes thin, flexible materials that maximize internal capacity while minimizing external bulk. The flexible construction allows the pouch to conform to the phone case's contours, maintaining a sleek profile that doesn't interfere with the user's ability to hold and grip the phone comfortably.

Inventive Principle:

Principle #30Flexible shells and thin films

4Adaptability or versatility

If the pouch is permanently attached to the phone case, then personal items are securely carried, but removal for wireless charging or car mounting becomes difficult

Engineering Contradiction:

Improvepersonal item securityVSAvoidpouch removal

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The pouch is attached to the phone case using dynamic, reversible connection mechanisms such as magnetic connectors, snap buttons, or Velcro strips. These attachments provide secure holding during normal use but can be easily detached with one hand when wireless charging or car mounting is needed, enabling quick transitions between different usage modes.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The attachment mechanism acts as an intermediary between the pouch and phone case, providing a balance between security and ease of removal. The magnetic or snap connection is strong enough to keep the pouch securely attached during everyday handling but weak enough to allow simple detachment without tools or complex operations.

Inventive Principle:

Principle #24Intermediary (Mediator)
