Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a protective casing is designed with a key structure for a specific electronic device, then the casing can effectively protect and operate that device, but the casing cannot be used with other electronic devices having different button positions

Engineering Contradiction:

Improvecompatibility with different electronic devicesVSAvoidstructure of key mechanism

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The resilient arm's length is designed as an adjustable parameter that can accommodate different button positions. By changing the effective length or position of the resilient arm, the key structure can adapt to various button locations on different electronic devices, thereby achieving versatility without requiring multiple specialized casings

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The protective casing is designed with a universal key structure that can serve multiple functions across different electronic devices. The resilient arm mechanism is configured to potentially trigger buttons at various positions, allowing a single casing design to protect and operate multiple types of electronic devices rather than being device-specific

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If separate protective casings are purchased for each electronic device, then each device receives dedicated protection, but the user incurs increased additional costs

Engineering Contradiction:

Improveprotection effectivenessVSAvoidnumber of casings required

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The protective casing is designed as a universal solution that can protect multiple electronic devices with different button configurations. The resilient arm mechanism is configured to potentially trigger buttons at various positions, allowing a single casing design to serve multiple devices, thereby reducing the quantity of casings needed while maintaining dedicated protection for each device

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Manufacturing precision

If the resilient arm length is fixed, then the manufacturing precision is improved, but the adaptability to different button positions is reduced

Engineering Contradiction:

Improveresilient arm length specificationVSAvoidaccommodation of different button distances

Core Design Contradiction:

Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

Inventive Principle:

Principle #35Parameter changes

AI summary

A protective casing is adapted for a first electronic device with a first button and a second electronic device with a second button. The protective casing includes a lower casing and an upper casing. The lower casing includes a partition member disposed therein. The partition member has a first resilient arm extended from a periphery of the partition member. The upper casing cooperates with the lower casing to form a first accommodating space, wherein the first accommodating space is above the partition member. When the first electronic device is accommodated in the first accommodating space, the first button is at a first distance from a bottom of the partition member. When the second electronic device is accommodated in the first accommodating space, the second button is at a second distance from the bottom of the partition member. A length of the first resilient arm covers the first and second distances.
