Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional charging interface is provided for charging the mobile intelligent terminal, then charging function is achieved, but water accumulates in the charging interface causing short-circuit risk
Solution Approach 1:
The patent replaces the conventional mechanical electrical charging interface with an optical charging interface. Light transmissive sheets are disposed on the housing to enable optical signal transmission for charging and data communication, eliminating the need for exposed electrical contacts that accumulate water and cause short-circuits.
Solution Approach 2:
The patent uses light transmissive sheets (thin films) integrated into the housing structure to create the charging interface. These sheets allow optical signals to pass through while maintaining the waterproof integrity of the housing, preventing water accumulation issues associated with traditional open electrical interfaces.
2Ease of operation
If a charging interface is provided on the mobile intelligent terminal, then charging capability is enabled, but waterproof performance is compromised
Solution Approach 1:
The patent substitutes electrical signal transmission through physical connectors with optical signal transmission through light transmissive sheets. This replacement maintains waterproof performance by eliminating openings in the housing while preserving charging capability through optical communication.
Solution Approach 2:
The light transmissive sheets serve multiple functions: they maintain the waterproof seal of the housing, enable optical charging, and facilitate data communication. This multi-functionality eliminates the need for separate charging ports that would compromise waterproofing.
3Reliability
If the mobile intelligent terminal uses optical-to-electrical conversion module for charging, then waterproof integrity is maintained, but device complexity increases
Solution Approach 1:
The optical-to-electrical conversion module handles multiple tasks including charging current reception, data communication, and authentication signals all through the same optical interface. This consolidation reduces the need for separate specialized components that would increase overall device complexity.

AI summary
This application provides a waterproof mobile intelligent terminal, a charger, and an optical charging control method. A housing of the mobile intelligent terminal is provided with a waterproof structure, to prevent water from causing damage to an electronic device inside the mobile intelligent terminal when the mobile intelligent terminal falls into water. The waterproof structure includes a waterproof external information interface. The external information interface includes a light transmissive sheet of the housing and an optical-to-electrical conversion module disposed inside the housing. The optical-to-electrical conversion module is configured to convert an optical signal that passes through the light transmissive sheet into an electric signal. When a user needs to charge the mobile intelligent terminal or transmit data to or from the mobile intelligent terminal, energy or the data may be carried on an optical signal, and a device, for example, the charger or an optical fiber, that can generate and output an optical signal, is aligned with the light transmissive sheet of the housing, so that the optical signal enters the housing through the light transmissive sheet and is received by the optical-to-electrical conversion module. Then, the optical-to-electrical conversion module converts the optical signal into an electric signal. The electric signal may be used to provide electric energy for the mobile intelligent terminal, transmit data, and the like. Therefore, in the technical solutions of this application, the mobile intelligent terminal does not need to be provided with a charging interface. Therefore, even after the mobile intelligent terminal is immersed in water, the user can safely charge the mobile intelligent terminal or transmit data to or from the mobile intelligent terminal without worrying about short-circuiting of the mobile intelligent terminal, thereby ensuring personal safety of the user.
