Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If DLNA is used for multimedia playback in home network, then interconnection between devices and file format conversion are improved, but device selection based on user requirements and adaptability to multiple functional devices are worsened
Solution Approach 1:
The patent introduces a gateway as an intermediary device in the home network that mediates between user instructions and target devices. The gateway obtains instructions, queries for suitable target devices based on predetermined conditions, and notifies selected devices to execute instructions. This intermediary mechanism enables adaptability to multiple functional devices while simplifying user operations, as users only need to send instructions to the gateway without directly selecting specific target devices.
2Ease of operation
If user directly sends instruction to specific device, then instruction execution is direct, but user operation complexity increases due to need for detailed device information knowledge
Solution Approach 1:
The patent implements a self-service mechanism where the gateway automatically queries for suitable target devices and selects the most appropriate device based on predetermined conditions, without requiring user input about device specifications. The system autonomously handles device selection by comparing device capabilities with instruction requirements, thereby simplifying user operations while eliminating the need for users to possess detailed device performance information.
3Productivity
If device functions are fully utilized through automatic selection, then user experience is improved, but system complexity for querying and evaluating devices increases
Solution Approach 1:
The patent employs parameter changes by establishing predetermined conditions and evaluation criteria for device selection. The gateway queries devices based on specific parameters such as device type, capability, and current state, comparing these parameters against instruction requirements to automatically select the most suitable device. This parameter-based approach enables efficient device selection and full utilization of device functions while managing system complexity through structured evaluation criteria.

AI summary
A method includes: an obtaining step, in which a first device in the home network obtains the instruction; a query step, in which the first device queries for at least one particular device meeting a predetermined condition in the home network; and a notification step, in which the first device notifies the particular device of the instruction. A user does not need to directly send an instruction to a particular device that executes the instruction; instead, the user only needs to make sure that any device in the home network obtains the instruction. The user can enable a most suitable device to execute the instruction automatically without knowing a large amount of detailed information such as device performance. Therefore, not only is full use of functions and features of devices in the home network made, but also user operations are significantly facilitated, improving user experience for users.
