Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a wireless charger is mounted to a cellphone case using existing methods, then the charger can be secured to the case, but the mounting system lacks robustness and compatibility with other accessory mounts

Engineering Contradiction:

Improvemounting stabilityVSAvoidaccessory compatibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The mounting system is divided into separate functional components: a retention ring with metal plate for magnetic attachment to the case, and a protrusion with metal plate on the charger. This segmentation allows the case to maintain its structural integrity while providing a dedicated mounting interface that doesn't interfere with other accessories.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The cellphone case is designed with a standardized bore and retention ring interface that can accommodate both the wireless charger and other accessory mounts. The magnetic mounting system provides a universal attachment method that maintains compatibility with various accessories while ensuring robust charger attachment.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Strength

If a magnetic mounting system is used to secure the wireless charger to the cellphone case, then the mounting becomes robust and stable, but the device complexity increases

Engineering Contradiction:

Improvemounting strengthVSAvoidmounting structure complexity

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The traditional mechanical screw or clip-based mounting systems are replaced with a magnetic mounting system. The metal plates with magnetic properties provide strong attachment forces without requiring complex mechanical fastening mechanisms, reducing overall device complexity while maintaining mounting strength.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The mounting function is merged with the existing case structure by integrating the retention ring and metal plate into the case design. This combines the structural support function with the magnetic attachment function, eliminating the need for separate mounting hardware and reducing device complexity.

Inventive Principle:

Principle #5Merging (Combining)

3Manufacturing precision

If a retention ring with metal plate is used to secure the wireless charger, then the alignment and stability are improved, but the manufacturing complexity increases

Engineering Contradiction:

Improvealignment precisionVSAvoidmanufacturing simplicity

Core Design Contradiction:

Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The retention ring with metal plate is pre-assembled and pre-aligned during the case manufacturing process. The bore is precisely positioned and the retention ring is installed before final case assembly, ensuring accurate alignment with the charger protrusion while simplifying the overall manufacturing process through staged assembly.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The metal plate is integrated within the retention ring structure, with the retention ring nested within the case bore. This nested arrangement ensures precise alignment through the hierarchical structure while simplifying manufacturing by combining multiple components into nested assemblies rather than separate parts requiring complex alignment.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

A system for mounting a wireless cellphone charger to a cellphone, including a cellphone case and a wireless cellphone charger mount. The cellphone case defines a bore and a recess disposed adjacent the bore and includes a shell and a first retention ring having a first metal plate receivable by the recess to secure the first retention ring to the shell. The wireless cellphone charger mount has a wireless cellphone charger, a second metal plate and an interface comprising a protrusion receivable by the bore. The wireless cellphone charger is securable to the cellphone case when the first retention ring is secured to the shell by aligning the protrusion and the bore and magnetically coupling the first and second metal plates.
