Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If traditional heat-dissipating fans and heat-dissipating holes are provided on components, then heat dissipation effect is improved, but dustproof and waterproof properties deteriorate
Solution Approach 1:
The fan device is divided into separate modular components: a fan body, a fan lid, and a fan-end connecting device. This segmentation allows the heat dissipation function to be isolated in a self-contained module that can be sealed independently, preventing dust and water ingress while maintaining effective heat dissipation through the fan's operation.
Solution Approach 2:
A cable serves as an intermediary element to transmit power and signals between the fan body and the external environment without requiring direct openings in the sealed housing. The cable passes through sealed interfaces, allowing electrical connection while maintaining the dustproof and waterproof integrity of the main device structure.
2Object-affected harmful factors
If dustproof and waterproof structures are implemented, then dustproof and waterproof properties are improved, but ease of maintenance of heat-dissipating fan deteriorates
Solution Approach 1:
The fan device is designed as a modular assembly with distinct components (fan body, fan lid, connecting device) that can be easily separated. The fan-end connecting device interfaces with the housing through a standardized connection, allowing the entire fan module to be quickly removed and replaced without disassembling the sealed housing structure, thus maintaining both protection and maintainability.
Solution Approach 2:
The fan-end connecting device incorporates pluggable electrical connections that can be quickly connected and disconnected. This dynamic connection system allows maintenance personnel to rapidly replace the fan module by simply plugging and unplugging the connector, eliminating the need for complex disassembly while preserving the sealed environment during maintenance operations.
3Stability of the object's composition
If fan device is integrated into housing, then structural integrity is improved, but adaptability for replacement and maintenance deteriorates
Solution Approach 1:
The fan device is designed as a separate module with its own housing (fan lid and fan body) rather than being permanently integrated into the main device housing. This modular segmentation maintains the overall structural integrity of each component while enabling easy replacement of the fan module through the fan-end connecting device interface.
Solution Approach 2:
The fan-end connecting device is designed with standardized interfaces that can accommodate different fan models and configurations. This universal connection design allows the same mounting structure to work with various fan devices, enhancing adaptability for replacement and maintenance while preserving structural integrity through consistent interface standards.
