Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual input of geographical location and channel setting is used, then the receiving apparatus can receive terrestrial wave digital signals, but the operation becomes troublesome and inconvenient when moving to a new region
Solution Approach 1:
The receiving apparatus automatically determines its own geographical location using GPS positioning and autonomously sets the receiving channel by querying the correspondence relationship between transmitting and receiving channels at the determined location, eliminating the need for manual user input and making the system self-configuring
Solution Approach 2:
The system pre-stores the correspondence relationship between transmitting channels and receiving channels at various geographical locations in advance, so that when the apparatus moves to a new region, it can quickly retrieve and apply the appropriate channel setting without requiring real-time manual configuration
2Device complexity
If manual channel setting is required, then the receiving channel can be set to correspond to transmitting channel, but the process becomes complex and troublesome
Solution Approach 1:
The apparatus automatically performs the channel correspondence setting by itself through GPS positioning and automatic querying of the stored channel mapping data, eliminating the need for users to manually configure the complex correspondence relationship between transmitting and receiving channels
Solution Approach 2:
The system uses GPS positioning data as an intermediary to automatically retrieve the corresponding channel setting information from the pre-stored map data, simplifying the complex channel configuration process into a single automatic lookup operation

AI summary
There are provided an image signal receiving apparatus, a method for setting a receiving channel of the image signal receiving apparatus, and a display apparatus. The method for setting the receiving channel comprises: storing (101) map information in the image signal receiving apparatus, wherein the map information comprises correspondence relationship between a transmitting channel and the receiving channel at each of different geographical positions; automatically determining (102) a geographical position where the image signal receiving apparatus is located; inquiring (103) the correspondence relationship between the transmitting channel and the receiving channel according to the geographical position where the image signal receiving apparatus is located; and setting (104) the receiving channel of the image signal receiving apparatus according to result of the inquiry. In the image signal receiving apparatus and the method for setting the receiving channel of the image signal receiving apparatus, a geographical position, where the image signal receiving apparatus is located, is determined automatically by a positioning module without inputting the geographical position where the image signal receiving apparatus is located manually, such that setting of the receiving channel of the image signal receiving apparatus after it moves in geographical position becomes more convenient, the troublesome manual setting is removed, and efficiency of the setting for the receiving channel is also improved.
