Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to determine whether an object has been heated by electromagnetic wave radiation, such as a microwave oven, as they either do not provide clear indication or are unable to detect the heating event after the object is removed from the oven.
Innovation Solution
An electromagnetic wave radiation detection member comprising a detection material with a liquid and discoloring substance enclosed in a bag that flows out upon radiation, adhering to a test substance to visibly indicate exposure to electromagnetic waves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a temperature indicating element is melted and flowed to indicate temperature, then it is possible to determine that the temperature has reached a predetermined temperature, but it is impossible to determine whether the object has been heated by a microwave oven
Solution Approach 1:
The detection system is segmented into multiple functional components: a temperature-sensitive bag containing liquid detection material, and a separate test paper with indicator substances. The bag releases the liquid material when a specific temperature is reached, and this liquid then reacts with the test paper to produce a color change. This segmentation allows the system to simultaneously detect temperature and identify the heating source (microwave vs. conventional heating).
Solution Approach 2:
The liquid detection material serves as an intermediary between the temperature indication mechanism and the heating source identification. When the bag is heated to a specific temperature, the liquid material flows out and acts as a mediator that reacts with the test paper's indicator substances, producing different color changes depending on whether the heating source was a microwave oven or conventional heat source.
2Temperature
If the temperature of an object is lowered when taken outside the microwave oven, then the object cools down, but it becomes impossible to detect that the object was destroyed by the heat of the microwave oven
Solution Approach 1:
The detection system performs preliminary action by capturing and recording the thermal history of the object during microwave heating. The temperature-sensitive bag is designed to respond to the specific temperature profile generated by microwave heating, and the test paper is pre-prepared with indicator substances that will react with the released liquid material to provide a permanent record of microwave exposure, even after the object cools down.
3Ease of operation
If a seal peels off or cutline breaks to notify heat-cooking completion, then it is possible to notify that heating has been completed, but it is impossible to determine whether the object has been heated by a microwave oven
Solution Approach 1:
The invention employs color changes as the primary indication mechanism. The test paper contains indicator substances that produce distinct color changes when exposed to the liquid detection material released from the heated bag. Different color patterns or intensities indicate different heating methods (microwave vs. conventional), providing both heating completion notification and heating method identification through visual color cues.
