Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a traditional thermometer design is used, then the structure is simple, but it is difficult to read at night due to insufficient visibility
Solution Approach 1:
The patent combines multiple functions into the thermometer device: temperature measurement, display, lighting, and power supply are integrated into a single floating device. The lighting device and display device are merged with the temperature measurement function, eliminating the need for separate reading devices and solving the visibility problem while maintaining reasonable structural complexity.
Solution Approach 2:
The floating thermometer serves multiple purposes: it measures temperature, displays readings digitally, provides illumination for night reading, and floats on water surfaces. This multi-functionality addresses the visibility issue without requiring additional separate devices, as the thermometer itself becomes its own reading and lighting device.
2Measurement precision
If the thermometer components are exposed to liquid, then temperature measurement is accurate, but internal components are damaged by liquid ingress
Solution Approach 1:
The thermometer is divided into separate functional zones: the probe portion that contacts liquid for measurement, and the sealed suspension chamber that houses electronic components. The mounting seat creates a transition zone with sealing structures that prevent liquid from reaching internal components while allowing the probe to remain exposed for accurate temperature measurement.
Solution Approach 2:
The mounting seat and mounting cover body act as intermediary sealed structures between the liquid environment and the internal electronic components. These intermediate sealing elements allow the probe to contact liquid for measurement while blocking liquid ingress to the control main board, display device, and lighting device.
3Ease of operation
If the thermometer floats on liquid surface, then it is easy to position and read, but internal components may be damaged by water ingress
Solution Approach 1:
The counterweight assembly provides downward force to balance the buoyancy of the floating chamber, stabilizing the thermometer's position on the liquid surface. This counterweight mechanism enables easy positioning and reading while the sealed mounting structures simultaneously prevent water ingress to internal components.
Solution Approach 2:
The mounting cover body and mounting seat form sealed enclosures that protect internal components from water ingress while allowing the device to float. These shell structures create a barrier between the external liquid environment and the internal electronics, enabling both floating operation and component protection.
