Engineering Contradiction Analysis
1Area of stationary object
If multiple devices transmit communication signals simultaneously in close proximity, then communication coverage is improved, but communication interference increases and bandwidth efficiency deteriorates
Solution Approach 1:
The patent implements dynamic transmission control where the electronic apparatus adjusts its transmission behavior based on real-time detection of surrounding devices. When another apparatus is detected within the transmission area, the system dynamically restricts further transmission. This dynamic adaptation allows the system to maintain communication coverage while avoiding interference from simultaneous transmissions.
Solution Approach 2:
The system employs feedback mechanisms by continuously monitoring the communication environment through reception signals. When a transmission is received from another apparatus, this feedback triggers the restricting process that prevents further transmission. This feedback loop ensures that communication coverage is maintained while interference is automatically prevented through real-time environmental awareness.
2Reliability
If the electronic apparatus continuously transmits signals to ensure communication reliability, then communication reliability is improved, but communication traffic volume increases and bandwidth is wasted
Solution Approach 1:
The patent applies partial action by transmitting signals only when necessary and not when another device is already transmitting. The restricting process prevents excessive transmission that would waste bandwidth, while still ensuring reliable communication when needed. This selective transmission maintains communication reliability without generating unnecessary traffic volume.
Solution Approach 2:
The system performs self-service by autonomously determining when to transmit and when to restrict transmission based on detected reception signals. This self-regulating mechanism ensures communication reliability is maintained through appropriate transmission while automatically preventing bandwidth waste from redundant transmissions.
3Productivity
If the electronic apparatus transmits signals in one-to-many communication mode, then communication efficiency is improved, but transmission interference increases when multiple devices are close
Solution Approach 1:
The patent implements dynamic control of one-to-many communication by allowing transmission only when no other apparatus is detected in the vicinity. When another device is present, the system dynamically switches to a restricted state, preventing interference. This dynamic approach maintains communication efficiency when appropriate while avoiding interference in close-proximity scenarios.
Solution Approach 2:
The system uses feedback from received signals to control its transmission behavior in one-to-many mode. When reception signals indicate another device is present, this feedback triggers the restricting process, preventing interference. This feedback mechanism preserves communication efficiency through one-to-many transmission while automatically preventing interference when multiple devices are close.

AI summary
An electronic apparatus comprises a communication unit and at least one processor. The communication unit performs wireless communication with an external device and a vehicle. (i) Upon receiving, via the communication unit, a reception signal transmitted from the external device through one-to-many communication, the at least one processor makes a determination based on the reception signal, about whether a first distance between the electronic apparatus and the external device is shorter than a distance reference value. (ii) Upon determining that the first distance is shorter than the distance reference value, the at least one processor performs a restricting process of restricting transmission of a transmission signal via the communication unit.
