Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a Bluetooth module and circuit board are added to the thermometer probe, then wireless data transmission capability is improved, but the overall volume and structural complexity increase
Solution Approach 1:
The patent combines the Bluetooth module, circuit board, and temperature sensor into an integrated probe assembly. The circuit board is embedded within the probe housing, and the Bluetooth module is mounted on the circuit board, creating a unified wireless thermometer unit that reduces overall system complexity while maintaining functionality.
Solution Approach 2:
The circuit board is nested within the probe housing structure, and the Bluetooth module is nested on the circuit board. This nested arrangement allows compact integration of multiple components within the probe, minimizing external complexity while enabling wireless communication capability.
2Ease of manufacture
If dry batteries are used to power the Bluetooth module, then ease of manufacture is improved, but reliability in high-temperature environments deteriorates
Solution Approach 1:
The patent changes the power supply parameter from dry batteries to a capacitor-based electrical accumulation device. This parameter change enables the thermometer to operate reliably in high-temperature environments (above 60°C) where dry batteries would fail, while still maintaining ease of manufacture through standard capacitor components and electrical connection structures.
3Measurement precision
If the thermometer probe is inserted into food for temperature detection, then measurement precision is improved, but the need to open the grill or oven door to read the dial increases operational complexity
Solution Approach 1:
The patent replaces the mechanical dial reading system with an electronic display and Bluetooth wireless transmission system. The temperature data detected by the sensor is processed electronically and transmitted wirelessly to a mobile device or display unit, eliminating the need to physically open the grill or oven door to read the temperature, thus improving ease of operation while maintaining measurement precision.
