Solution Overview

Problem

Existing filter devices require separate mounting of measurement portions and antenna assemblies, leading to potential mistakes and increased costs due to the need for dual components on the lid body.

Innovation Solution

A measurement unit is designed with a case that integrates an antenna unit and a sensor, allowing both to be mounted as a single component, with the antenna unit positioned near one end of the case and the sensor inside, enabling simultaneous measurement and IC tag reading without the need for separate positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If separate mounting of measurement portion and antenna assembly is performed, then each component can be independently positioned, but mounting complexity and cost increase

Engineering Contradiction:

Improvemounting simplicityVSAvoidnumber of components

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent combines the measurement portion and antenna assembly into a single integrated unit that is mounted as one component on the lid body, eliminating the need for separate mounting operations and reducing the number of parts while maintaining independent positioning capabilities

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If multiple components are mounted on lid body, then functional requirements are met, but mistake in mounting increases

Engineering Contradiction:

Improvemounting accuracyVSAvoidnumber of mounting operations

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

By integrating the measurement portion and antenna assembly into a single mounted unit, the patent reduces the number of mounting operations from two separate steps to one, thereby minimizing the opportunity for mounting mistakes while ensuring reliable positioning of both functional components

Inventive Principle:

Principle #5Merging (Combining)

3Volume of moving object

If antenna unit and sensor are positioned separately, then signal interference is reduced, but device size increases

Engineering Contradiction:

Improvemeasurement unit sizeVSAvoidsignal interference

Core Design Contradiction:

Volume of moving objectVSObject-affected harmful factors

Solution Approach 1:

The patent positions the antenna unit and sensor in different spatial dimensions within the measurement unit, allowing them to be mounted close together for compactness while maintaining sufficient separation to minimize signal interference, thus achieving both small device size and reduced interference

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
