Solution Overview

Problem

Conventional thermometer sheaths for ear thermometers have a low yield rate during manufacturing and are difficult to assemble or detach from the probe due to weak strength.

Innovation Solution

A probe cover design featuring a conical main body, annular elastomer, flange, and convex rib structures that protrude upwardly from the flange, allowing for easy engagement and disengagement from the probe.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the conventional thermometer sheath structure is used, then the manufacturing process is simple, but the yield rate is low and the assembly/detachment is difficult

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidyield rate
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The probe cover is divided into multiple functional segments: a conical main body for insertion, a flange for positioning, and multiple convex rib structures for engagement. This segmentation allows each part to perform its specific function optimally, improving both manufacturing yield and assembly ease.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The convex rib structures are strategically positioned on the flange to provide localized engagement points with the probe. This local quality enhancement at critical areas improves the overall strength and assembly reliability without complicating the entire structure.

Inventive Principle:
Principle #3Local quality

2Device complexity

If the conventional thermometer sheath structure is used, then the structure is simple, but the strength is weak making assembly/detachment difficult

Engineering Contradiction:
Improvestructural simplicityVSAvoidsheath strength
Core Design Contradiction:
Device complexityVSStrength

Solution Approach 1:

The convex rib structures are pre-formed on the flange during manufacturing, creating built-in engagement features that automatically interact with the probe during assembly. This preliminary action eliminates the need for complex assembly mechanisms while providing sufficient strength.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The conical main body employs a curved conical shape that tapers smoothly, providing both structural integrity and ease of insertion. The curvature distributes stress evenly during assembly and detachment, enhancing strength without increasing complexity.

Inventive Principle:
Principle #14Spheroidality (Curvature)
