Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If a mobile device is made thinner and more compact, then portability and aesthetics are improved, but the device becomes more susceptible to damage from drops and impacts

Engineering Contradiction:
Improvedevice thicknessVSAvoiddamage resistance
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The patent applies beforehand cushioning by incorporating a foam material between theclam shell halves that compresses during impact to absorb energy before the force reaches the device. The foam is positioned to contact the device during closure, providing pre-positioned protection that activates upon impact occurrence.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The patent implements nesting by placing the mobile device within the cavity formed by the clam shell halves, and positioning the foam material between the device and the shell structure. This nested arrangement allows the foam to surround and protect the device from multiple directions during impact.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Strength

If existing protectors use a rigid shell design, then impact resistance is improved, but the protector adds excessive bulk and weight to the device

Engineering Contradiction:
Improveimpact resistanceVSAvoidprotector weight
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The patent employs a flexible foam material instead of a rigid shell to provide impact protection. The foam compresses under impact forces to absorb energy while maintaining a thin profile when not in use, avoiding the bulk and weight associated with rigid protective shells.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The patent changes the physical state parameter of the protective material from rigid (solid shell) to flexible (compressible foam). This parameter change allows the material to provide equivalent impact resistance through compression rather than rigid structural support, reducing overall weight and bulk.

Inventive Principle:
Principle #35Parameter changes

3Weight of moving object

If existing protectors use foam material, then weight reduction is achieved, but the protectors lack structural support and durability

Engineering Contradiction:
Improveprotector weightVSAvoidstructural support
Core Design Contradiction:
Weight of moving objectVSStrength

Solution Approach 1:

The patent creates a composite protective structure by combining foam material with theclam shell halves. The foam provides lightweight cushioning while the shell halves contribute structural rigidity and durability. This composite approach achieves both weight reduction and structural support that neither material could provide alone.

Inventive Principle:
Principle #40Composite materials

4Reliability

If a clam shell protector is designed to fully enclose the device, then comprehensive protection is improved, but the protector becomes difficult to open and close

Engineering Contradiction:
Improveprotection coverageVSAvoidopening and closing ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent divides the protective structure into two separableclam shell halves that can be independently opened and closed. This segmentation allows the device to be accessed by separating the halves rather than opening a single enclosed structure, maintaining comprehensive protection when closed while improving operational ease.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The foam material acts as an intermediary element positioned between theclam shell halves. During closure, the foam compresses to accommodate the device and facilitate the joining of the two halves, reducing friction and resistance that would otherwise make opening and closing difficult.

Inventive Principle:
Principle #24Intermediary (Mediator)
