Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing content playback devices do not effectively play back content corresponding to a person's perceived temperature, which can differ from actual temperature, leading to discomfort.

Innovation Solution

A content playback device that receives perceived temperature information via a communication network, stores date and temperature data, and selects playback content based on this information to output audio or video signals corresponding to the perceived temperature and season.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If content playback devices use actual temperature data for content selection, then the system is simple to operate, but the content does not match the user's perceived temperature experience

Engineering Contradiction:

Improvetemperature measurement accuracyVSAvoiduser comfort

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The patent changes the temperature parameter from actual physical temperature to perceived temperature, which accounts for human physiological response to environmental conditions. This is achieved by receiving perceived temperature information from external devices rather than using raw sensor data, thereby making the content selection match user experience while maintaining system simplicity

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent introduces an intermediary component (perceived temperature information receiver) that translates actual temperature into user-perceived temperature. This intermediary layer processes the temperature data through communication interfaces to reflect human experience, resolving the contradiction between measurement accuracy and user comfort

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the device receives and processes perceived temperature information from external devices, then content matching user experience is improved, but device complexity increases

Engineering Contradiction:

Improvecontent adaptation to environmentVSAvoidsystem structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements multi-functionality by combining the perceived temperature information receiver with the existing content playback functionality. The communication interface serves multiple purposes: receiving temperature data, processing it, and using it for content selection, thereby reducing overall system complexity despite added adaptability

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent performs preliminary action by pre-receiving and storing perceived temperature information before content selection occurs. This allows the system to have temperature data ready when needed for content playback, simplifying the real-time processing requirements and reducing operational complexity

Inventive Principle:

Principle #10Preliminary action

AI summary

A content playback device includes: a network interface that receives the current perceived temperature information for a person in a specific area from a server via a communication network; a memory that stores the perceived temperature information and date information indicating the current date; and a central processing unit (CPU) that causes the memory to store the perceived temperature information received by the network interface, selects playback content from a plurality of pieces of content, based on the perceived temperature information and the date information, and plays back the playback content.
