Communication Terminal Content Exchange System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication terminals limit the chances of users enjoying video and music content, as content availability is restricted to user evaluations and lack mechanisms to promote usage, leading to limited exposure and access for users.
Innovation Solution
A communication terminal-based contents exchange system that includes a communication device, operation unit, memory, and controller, which repeatedly transmits request information, determines content transmission based on flag information, and stores received content data, allowing for the exchange of image and voice content between terminals, thereby increasing content accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If content exchange is limited to user evaluations, then content quality is maintained, but content accessibility and distribution range are reduced
Solution Approach 1:
The patent segments the content exchange system into two independent components: evaluation information (quality indicators) and distribution information (accessibility indicators). This allows the system to maintain content quality through evaluations while simultaneously expanding accessibility through automated distribution based on distribution information, resolving the contradiction between quality control and wide distribution
Solution Approach 2:
The patent introduces an intermediary mechanism (the content exchange system with separate evaluation and distribution channels) that decouples the relationship between user evaluation and content distribution. This intermediary allows content to be evaluated for quality while being distributed independently based on distribution information, enabling both quality maintenance and accessibility expansion
2Productivity
If repeated transmission of request information is implemented, then content distribution efficiency is improved, but communication overhead increases
Solution Approach 1:
The patent implements periodic transmission of request information at predetermined intervals rather than continuous transmission. This periodic action maintains content distribution efficiency by ensuring regular content exchange while reducing communication overhead by eliminating unnecessary transmissions during intervals, thus resolving the contradiction between productivity and information loss

AI summary
Opportunity of enjoying video and music is enlarged. A content reproducing device is used in a contents exchange system including a plurality of contents reproducing devices. The content reproducing device includes a short range communication unit, a memory, a control unit, and a speaker. The short range communication unit communicates request information, response information, content data and flag information to/from content reproducing devices. The control unit controls the short range communication unit so that content data is transmitted. The control unit controls the memory such that the content data and the flag information received by the short range communication unit are stored.
