Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a phone case is designed with fixed mass production styles, then manufacturing efficiency is improved, but the ability to meet individuality needs deteriorates

Engineering Contradiction:
Improvemanufacturing efficiencyVSAvoidindividuality expression
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The phone case is divided into a base case and detachable modeling modules. The base case maintains standardized production for efficiency, while the modeling modules can be independently designed and combined to express individuality. This segmentation allows mass production of the base case while enabling personalized customization through module selection and combination.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The modeling modules are designed with universal attachment interfaces that can be used across different phone case models. The same set of modular components can create multiple different designs and configurations, allowing a limited production set to serve diverse customization needs while maintaining manufacturing efficiency.

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

2Adaptability or versatility

If a phone case allows for personalized customization, then individuality expression is improved, but device complexity increases

Engineering Contradiction:
Improvepersonalized customizationVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

By segmenting the customization system into standardized modeling modules with uniform attachment mechanisms, the complexity is distributed and managed through modular components rather than a complex integrated system. Each module remains simple in structure while the combination capability provides the customization functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The magnetic attachment mechanism acts as an intermediary that simplifies the connection between modeling modules and the base case. This magnetic interface provides a simple, reliable attachment method that reduces structural complexity compared to mechanical fastening systems, while still enabling easy customization and module replacement.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If detachable modeling modules are used for customization, then ease of operation is improved, but reliability of attachment deteriorates

Engineering Contradiction:
Improvemodule detachabilityVSAvoidattachment stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The mechanical attachment system is replaced with a magnetic attachment system. The magnetic force provides reliable and stable attachment of the modeling modules to the base case, while still allowing easy detachment when needed. This substitution eliminates the complexity of mechanical fasteners while maintaining both ease of operation and attachment reliability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The attachment mechanism utilizes magnetic field strength as a controllable parameter. By adjusting the magnetic force intensity, the system achieves optimal balance between secure attachment during normal use and easy detachment for customization. The magnetic attraction provides sufficient holding force for reliability while requiring minimal force for detachment, satisfying both requirements.

Inventive Principle:
Principle #35Parameter changes

AI summary

A modular individualized phone case is provided according to the present application, which relates to the technical field of phone accessories. The modular individualized phone case includes a case body, a back plate and a modular modeling component. The back plate is detachably arranged in the case body, the back plate is a ferromagnetic metal plate, and the modular modeling component is attracted and fixed onto a rear side surface of the back plate. The modular modeling component includes multiple modeling modules which can be combined to form different looks. The modeling modules are magnetic attraction sheets. The modeling modules are attracted on the rear side of the back plate and combined to form individualized designs, and then the back plate is put into the case body. The modeling modules of the individualized design can be exhibited through the transparent case body. As such, various different rear-view looks (depending on the number of modeling modules, the more the number is, the more diverse the overall look is) can be obtained, which can meet the needs of people for showcasing individuality and pursuing uniqueness.
