Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Barbecue temperature probes lack guidance on the outer surface temperature, posing a risk of burns to users when handling the probe after cooking due to high surface temperatures.
Innovation Solution
A barbecue temperature probe with a temperature sensing portion on its outer surface that changes morphological characteristics with temperature changes, allowing users to intuitively determine the surface temperature without additional devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the probe is used in high-temperature cooking environments, then the temperature monitoring function is improved, but the outer surface temperature becomes dangerously high causing burn risks
Solution Approach 1:
The patent applies a temperature-sensitive color-changing material on the outer surface of the probe. When the probe surface temperature exceeds a safe threshold (e.g., 50°C), the material changes color to visually warn users. This resolves the contradiction by maintaining the probe's high-temperature measurement capability while adding a passive visual warning system that prevents user contact during dangerous temperature conditions.
2Device complexity
If no external devices are used for temperature monitoring, then the device complexity is reduced, but the user cannot estimate the outer surface temperature
Solution Approach 1:
The probe performs self-monitoring of its outer surface temperature using an integrated temperature-sensitive material. The probe itself provides the temperature information through color change, eliminating the need for external monitoring devices. This resolves the contradiction by keeping the probe structure simple while enabling it to self-report its surface temperature status through the color-changing indicator.
