Solution Overview
Problem
Current electronic thermometer devices for rapid body temperature measurement are complex, costly, and fail to ensure proper assembly of a disposable sheath, leading to potential cross-infection and user inconvenience.
Innovation Solution
An electronic thermometer design that uses the axial reciprocating motion of a probe within a disposable sheath to trigger a control switch, ensuring pre-heating only when the sheath is assembled, employing a mechanical, contact, or reluctance switch mechanism to initiate the measurement process, thereby preventing cross-infection and simplifying the device structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical switch and optical probing are used to detect probe position, then the heating can be initiated only when specific position requirements are met, but the structure becomes more complicated and production cost increases
Solution Approach 1:
The patent extracts the position detection function from complex mechanical switches and optical probing systems, retaining only the essential function of detecting probe insertion status. This simplification reduces structural complexity while maintaining reliable control over heating initiation.
Solution Approach 2:
The patent replaces complex mechanical switch and optical probing systems with a simpler mechanical detection mechanism that uses the probe's own movement to trigger the heating function. This substitution reduces device complexity while maintaining the required reliability for controlled heating initiation.
2Productivity
If the probe position is detected to initiate heating, then the measurement speed and accuracy are improved, but the disposable sheath assembly requirement is not ensured, leading to cross-infection risk
Solution Approach 1:
The patent implements preliminary action by requiring the disposable sheath to be properly assembled on the probe before the heating and measurement process can be initiated. The control mechanism detects the sheath's presence and position, ensuring that heating only begins when the sheath is correctly in place, thereby preventing cross-infection while maintaining fast measurement capability.
Solution Approach 2:
The patent introduces the disposable sheath as an intermediary element between the probe and the measurement environment. The control mechanism uses the sheath's position as an intermediate condition to enable or disable heating, ensuring that the sheath must be properly assembled before measurement can proceed, thus eliminating cross-infection risk.
3Reliability
If complex components are used for position detection and heating control, then the heating initiation can be precisely controlled, but the production cost increases
Solution Approach 1:
The patent extracts and retains only the essential function of position detection and heating control, eliminating unnecessary complex components. This extraction approach maintains precise control over heating initiation while significantly reducing production costs by using simpler, more economical components.
Solution Approach 2:
The patent employs disposable sheaths as part of the cost-effective solution. By making the sheath disposable and integrating its position detection into the control mechanism, the system achieves reliable heating control at lower production cost, as the sheath is replaced after each use and does not require expensive recovery or recycling mechanisms.
