Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single remote automobile diagnosis instrument is used, then the maintenance funds and professional qualifications requirements are reduced, but the diagnosis accuracy and efficiency are insufficient
Solution Approach 1:
The patent combines multiple remote terminals (first remote terminal and second remote terminal) to work together on a single diagnosis task. The first remote terminal performs initial diagnosis, and when accuracy is insufficient, a second remote terminal is invoked to perform additional diagnosis and cross-validation, thereby improving overall diagnosis accuracy while maintaining remote accessibility.
Solution Approach 2:
The control terminal acts as an intermediary that coordinates between the service terminal, multiple remote terminals, and the automobile. It manages the invocation of additional remote terminals when diagnosis accuracy is insufficient, facilitating collaborative diagnosis without requiring direct complex interactions between all components.
2Device complexity
If a single remote terminal performs diagnosis, then the system complexity is reduced, but the diagnosis efficiency and completeness are degraded
Solution Approach 1:
The system dynamically adjusts its complexity based on diagnosis needs. The control terminal monitors diagnosis results and automatically determines whether to invoke additional remote terminals. When the first remote terminal's diagnosis accuracy is sufficient, the system operates with minimal complexity; when accuracy is insufficient, the system dynamically expands to include a second remote terminal, thereby optimizing efficiency without unnecessary complexity.
Solution Approach 2:
The diagnosis process is segmented into multiple stages: initial diagnosis by the first remote terminal, accuracy evaluation by the control terminal, and conditional secondary diagnosis by a second remote terminal. This segmentation allows the system to maintain simplicity for routine cases while enabling complex multi-terminal collaboration only when necessary for difficult diagnoses.
3Measurement precision
If multiple remote terminals are used for simultaneous diagnosis, then the diagnosis accuracy and efficiency are improved, but the system complexity and coordination requirements increase
Solution Approach 1:
The control terminal serves as a central intermediary that manages all communications and coordination between the service terminal and multiple remote terminals. It receives diagnosis results from the first remote terminal, evaluates accuracy, and when necessary, invokes a second remote terminal while managing the interaction between all components, thereby enabling accurate multi-terminal diagnosis without requiring complex direct coordination between all terminals.
Solution Approach 2:
The system implements a feedback mechanism where the control terminal evaluates the diagnosis accuracy provided by the first remote terminal and uses this feedback to determine whether to invoke additional remote terminals. This feedback-driven approach ensures that multiple terminals are engaged only when necessary, optimizing the balance between diagnosis accuracy and system complexity.

AI summary
Disclosed are a remote automobile diagnostic method and apparatus, and a computer device. The method is applicable to a device side. A remote connection is established to a target terminal, and parameter information of a to-be-diagnosed automobile is transmitted to the target terminal, so that the to-be-diagnosed automobile can be directly diagnosed by the target terminal side. During the establishment of the remote connection to the target terminal, a second connection request signal may be transmitted to an operating terminal, to establish a remote connection to the operating terminal, so that the operating terminal can remotely control the device side and indirectly remotely diagnose the to-be-diagnosed automobile. That is, remote diagnosis is performed on the to-be-diagnosed automobile by two remote terminals. In this way, the efficiency of the remote diagnosis on the to-be-diagnosed automobile by the remote terminals can be enhanced.
