Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If hard-wired connections are used for audio inputs, then connection reliability is improved, but device versatility deteriorates

Engineering Contradiction:

Improveconnection reliabilityVSAvoidinput connectivity options

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent combines both hard-wired and wireless input capabilities into a single portable speaker system. The speaker includes traditional hard-wired audio input ports (AUX, USB) as well as integrated wireless transmitters that support Bluetooth and other wireless protocols, allowing the device to accept audio inputs through multiple connection types simultaneously.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The portable speaker is designed with multi-functional input capabilities, supporting both wired and wireless connection methods. The device can function as a traditional wired speaker while also serving as a wireless audio receiver, making it adaptable to various source devices and connection preferences.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If wireless transmitters are integrated into the portable speaker, then device versatility is improved, but device complexity deteriorates

Engineering Contradiction:

Improveinput connectivity optionsVSAvoidsystem structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The wireless transmitters are detachably housed within the portable speaker enclosure, allowing them to be nested inside the main device when not in use. This nesting approach integrates the wireless functionality into the speaker's overall structure without creating separate external components.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The wireless transmitter components are designed as detachable modules that can be separated from the main speaker unit. This segmentation allows for independent maintenance, replacement, or upgrading of wireless components without affecting the core speaker functionality.

Inventive Principle:

Principle #1Segmentation
