Solution Overview

Problem

Existing cell phone cases do not adequately accommodate wider items such as smoking apparatuses and rolling papers, limiting their convenience for smokers.

Innovation Solution

A mobile device case with a compartment featuring vertically separated sections to securely hold loose plant-based combustibles and a rolled smoking apparatus, along with a sliding lid for easy access and secure storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a cell phone case includes compartments for small items like cards or cash, then it provides basic storage functionality, but it cannot accommodate wider items such as smoking apparatuses and rolling papers

Engineering Contradiction:
Improvestorage capabilityVSAvoidcase structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The case is divided into multiple compartments with different functions: a first compartment for small items (cards, cash) and a second compartment for smoking apparatuses and rolling papers. This segmentation allows each compartment to be optimized for its specific purpose while maintaining overall case functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The second compartment is designed with increased width dimension compared to traditional phone case compartments, specifically to accommodate smoking apparatuses. This dimensional expansion in the width direction enables storage of wider items without compromising the structural integrity of the case.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If a separate carrying case is used for smoking apparatuses and rolling papers, then adequate storage space is provided, but convenience is reduced as users must carry multiple cases

Engineering Contradiction:
Improvestorage spaceVSAvoidconvenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The invention merges the phone case with a dedicated smoking apparatus storage compartment into a single integrated unit. The second compartment is specifically designed to hold smoking apparatuses and rolling papers, eliminating the need for a separate carrying case and improving user convenience.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cell phone case serves multiple functions: protecting the phone, storing small personal items in the first compartment, and storing smoking apparatuses and rolling papers in the second compartment. This multi-functionality consolidates what would traditionally require separate cases into one universal accessory.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If a compartment is designed to hold both loose plant-based combustibles and rolled smoking apparatuses, then storage versatility is improved, but the compartment structure becomes more complex

Engineering Contradiction:
Improvestorage versatilityVSAvoidcompartment structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The second compartment is further segmented into a second section for loose plant-based combustibles and a third section for rolled smoking apparatuses. This internal segmentation allows the compartment to accommodate different types of smoking materials while maintaining an organized structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The compartment structure uses nested sections where the second and third sections are integrated within the broader second compartment. This nesting approach allows multiple storage functions within a unified compartment boundary, managing complexity through hierarchical organization.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

A cell phone case with a storage compartment that has multiple sections and a slidable lid. The storage compartment is on the rear side of the case. The slidable lid is contained by a lip that ensures the lid slides only in one direction laterally and stays attached to the cell phone case storage compartment.
