Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the touch screen is exposed outside the protective case, then the touch screen is easily broken, but if the protective case covers the touch screen completely, then the touch screen becomes inaccessible

Engineering Contradiction:

Improvetouch screen protectionVSAvoidtouch screen accessibility

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The protective case is divided into a first covering part and a second covering part that can rotate relative to each other. The second covering part can be rotated to expose the touch screen while the first covering part remains stationary, providing both protection and accessibility.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The protective case incorporates a rotatable mechanism that allows the second covering part to dynamically change position between covering and exposing the touch screen, enabling the case to adapt between protection mode and usage mode.

Inventive Principle:

Principle #15Dynamics

2Object-affected harmful factors

If the protective case is designed to fully cover the electronic device, then scratch protection is improved, but heat dissipation becomes inadequate

Engineering Contradiction:

Improvescratch protectionVSAvoidheat dissipation

Core Design Contradiction:

Object-affected harmful factorsVSTemperature

Solution Approach 1:

The protective case incorporates heat dissipation holes at specific locations where heat generation is expected, and includes a heat dissipation plate in thermal contact with the electronic device. This provides localized heat dissipation functionality while maintaining overall protective coverage.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

A heat dissipation plate is introduced as an intermediary component between the electronic device and the protective case. The plate conducts heat away from the device through dedicated heat dissipation holes, enabling thermal management while maintaining the protective enclosure.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If the protective case uses a rotatable covering part to cover the touch screen, then scratch protection is improved, but usability deteriorates due to rotation requirement

Engineering Contradiction:

Improvetouch screen scratch protectionVSAvoidoperation convenience

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The protective case is segmented into a stationary first covering part and a rotatable second covering part. The first covering part provides continuous protection without requiring user action, while the second covering part can be rotated when needed, dividing the protective functions between passive and active components.

Inventive Principle:

Principle #1Segmentation

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution provides enhanced usability, scratch protection, and efficient heat dissipation for electronic devices, ensuring the touch screen is accessible while maintaining device safety and performance.

Implementation Method 1

the heat guiding layer contacts with the electronic device so that the heat of the electronic device conducts to the metal piece from the heat carrying layer via the heat removing layer, thus dissipating the heat to air

Methodology Applied

Scientific EffectThermal conduction: Conduction (thermal)

Implementation Method 2

the first covering part further includes a first adhesive layer configured around the internal face thereof so as to connect the first covering part with the front face of the electronic device

Methodology Applied

Scientific EffectAdhesion: Adhesive

AI summary

A protective case for an electronic device contains a first covering part and a second covering part which are connected together to define a hollow accommodation chamber for housing an electronic device. The second covering part couples with a back face of the electronic device and includes a heat removal groove for accommodating a heat dissipation plate, and when the electronic device is housed in the accommodation chamber, it contacts with the heat dissipation plate. The first covering part connects with a front face of the electronic device by using its internal face and includes a transparent visible window aligning with a touch screen of the front face of the electronic device. The accommodation chamber includes at least one receiving interface corresponding to at least one peripheral port of the electronic device and includes at least one button port for extending at least one button of the electronic device outwardly.
