Solution Overview

Problem

Existing sticking type thermometers face a decrease in measurement accuracy due to reduced adhesive strength when repeatedly used, leading to increased costs with disposable alternatives.

Innovation Solution

A sticking type thermometer with a replaceable sheet-like sticking member that can be peeled off and replaced, maintaining the thermometer's body temperature measurement unit and cases, ensuring consistent accuracy without increasing costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the thermometer uses a sticking tape to attach to the body surface, then the thermometer can be easily attached and used, but the adhesive strength decreases when repeatedly used, causing measurement accuracy to deteriorate

Engineering Contradiction:

Improveease of attachmentVSAvoidbody temperature measurement accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The thermometer is divided into two separate parts: a reusable main body portion (containing the temperature detector and processing circuit) and a replaceable sticking member (adhesive layer). This segmentation allows the sticking member to be replaced when adhesive strength decreases, while the expensive main body portion is reused, thus maintaining measurement accuracy without increasing costs.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The sticking member is designed to be discarded after use (or when adhesive strength decreases) and recovered/replaced with a new one, while the main body portion is retained and reused. This approach maintains measurement accuracy by ensuring fresh adhesive contact with the body surface, while avoiding the need to discard the entire thermometer.

Inventive Principle:

Principle #34Discarding and recovering

2Measurement precision

If the thermometer is disposed of after each use (disposable type), then measurement accuracy is maintained, but the cost increases

Engineering Contradiction:

Improvebody temperature measurement accuracyVSAvoidcost

Core Design Contradiction:

Measurement precisionVSQuantity of substance

Solution Approach 1:

The thermometer is segmented into a valuable main body portion (temperature detector, processing circuit) and a low-cost sticking member. This allows selective replacement of only the inexpensive sticking member while retaining the expensive main body, thus maintaining measurement accuracy without incurring the full cost of a disposable thermometer.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The inexpensive sticking member is discarded after use, while the expensive main body portion is recovered and reused. This approach maintains measurement accuracy by ensuring each use has a fresh sticking member, while significantly reducing costs by reusing the main body portion across multiple uses.

Inventive Principle:

Principle #34Discarding and recovering

3Ease of operation

If the sticking tape covers the entire body surface side of the thermometer, then the thermometer can be easily attached to the body surface, but the adhesive strength decreases when repeatedly used

Engineering Contradiction:

Improveease of attachmentVSAvoidadhesive strength durability

Core Design Contradiction:

Ease of operationVSDuration of action of stationary object

Solution Approach 1:

The sticking member is designed as a consumable component that is discarded when adhesive strength decreases and recovered/replaced with a new one. This ensures the thermometer can be easily attached to the body surface with each new sticking member while maintaining adhesive strength durability through systematic replacement rather than attempting to maintain a single long-term adhesive bond.

Inventive Principle:

Principle #34Discarding and recovering

AI summary

A sticking type deep-body thermometer is provided that includes a body temperature measurement unit having a wiring substrate on which four temperature sensors and a processing circuit are mounted. The thermometer includes an upper case accommodating the body temperature measurement unit, an lower case that is in close contact with the upper case and a peripheral edge portion, and a sticking member stuck to an outer side surface of the lower case. The sticking member is formed in a sheet-like shape, has a pair of sticking surfaces with adhesiveness, and one sticking surface of the pair of sticking surfaces is stuck to the outer side surface of the lower case in a peelable manner.
