Solution Overview

Problem

Existing non-face-to-face electronic commerce methods face limitations in real-time communication and transaction efficiency, particularly when using large-screen displays like smart TVs, due to the need for remote controls and text/audio communication, which are cumbersome and time-consuming.

Innovation Solution

A commerce service that enables real-time communication between sellers and purchasers through voice, audio, and video data exchange using a display device without a camera or microphone, allowing product introduction and purchase consultation via a smart TV or digital TV, with features like speech-to-text conversion and remote control functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If text or audio communication is used between purchaser and seller through TV, then non-face-to-face shopping is enabled, but communication efficiency is low and transaction time is long

Engineering Contradiction:

Improvenon-face-to-face shopping capabilityVSAvoidtransaction efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent replaces text-based remote control input with voice recognition technology. The TV set includes a voice recognition unit that captures and processes spoken commands, converting them into control signals. This substitutes the mechanical remote control operation with acoustic field-based voice recognition, significantly improving communication efficiency and transaction speed while maintaining non-face-to-face shopping capability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a voice recognition unit as an intermediary between the purchaser and the TV system. This intermediary captures voice inputs, converts them to text or commands, and transmits them to the TV controller, thereby mediating the interaction and eliminating the need for direct manual remote control operation

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If remote control is used to select items on TV, then product selection is possible, but operation convenience is poor

Engineering Contradiction:

Improveitem selection capabilityVSAvoidtime to complete purchase

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent replaces manual remote control operations with voice recognition technology. The voice recognition unit captures spoken commands and converts them into control signals that directly operate the TV interface. This substitution eliminates the time-consuming process of navigating through menus with a remote control, significantly reducing the time required to complete purchases while improving operational convenience

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
