Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Bluetooth automatic registration is used for device pairing, then ease of operation is improved, but the ability to transmit large amounts of video data deteriorates
Solution Approach 1:
The patent divides the data transmission process into two segments: small data (pairing information, key data) transmitted via Bluetooth, and large data (video data) transmitted via a separate communication protocol such as Wi-Fi or DisplayPort. This segmentation allows each communication channel to be optimized for its specific data type, resolving the contradiction between ease of pairing and video data transmission capacity.
Solution Approach 2:
The patent introduces an intermediary mechanism where key data is first exchanged via Bluetooth to establish a pairing relationship, which then enables subsequent video data transmission through a different communication channel. The key data acts as a mediator that bridges the two communication methods, allowing the system to leverage the strengths of both Bluetooth (ease of pairing) and other protocols (video data capacity).
2Quantity of substance
If a separate communication method is required for video data transmission, then video data transmission capacity is improved, but device complexity increases
Solution Approach 1:
The patent implements multi-functionality by enabling the image display apparatus to operate with multiple communication protocols (Bluetooth for pairing, and other protocols like Wi-Fi or DisplayPort for video data). The system universally supports both communication methods, allowing it to adapt to different data transmission needs without requiring separate dedicated hardware for each function, thereby managing complexity while maintaining versatility.
Solution Approach 2:
The patent applies preliminary action by using Bluetooth to first establish the pairing relationship and exchange key data before initiating video data transmission through the separate communication channel. This preliminary setup simplifies the overall process by automating the configuration phase, so that when video transmission begins, the communication path is already established and optimized.
3Adaptability or versatility
If mirroring is performed between multiple image display apparatuses, then adaptability is improved, but key data management complexity increases
Solution Approach 1:
The patent uses copying by transmitting key data from a first image display apparatus to a second image display apparatus through a mobile terminal. The key data is copied and shared across multiple devices, enabling them to establish pairing relationships without requiring unique complex configuration for each device. This copying mechanism simplifies key data management while supporting multi-device mirroring capability.
Solution Approach 2:
The patent introduces a mobile terminal as an intermediary that facilitates key data exchange between multiple image display apparatuses. The mobile terminal acts as a mediator that collects, manages, and distributes key data to enable pairing between different display devices, thereby simplifying the key data management complexity that would otherwise arise from direct device-to-device configuration.
