Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional portable medical device covers are easily separable, posing a safety risk as infants and toddlers can access and swallow batteries, particularly small button cells.

Innovation Solution

A portable medical device case design featuring a cover that requires an external tool to separate, incorporating a fastening part and a hole for the tool to press, ensuring the cover can only be opened with a specific tool, preventing accidental battery exposure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a conventional cover structure is used, then the cover can be easily separated for battery replacement, but infants and toddlers can also easily separate it causing safety accidents

Engineering Contradiction:

Improveease of separationVSAvoidbattery swallowing risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

An external tool acts as an intermediary between the user and the cover fastening mechanism. The tool must be inserted through a hole in the main body to press the fastening part, creating a mediated interaction that prevents direct access by infants while enabling adult operation for battery replacement.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If the cover is made difficult to separate to prevent infant access, then safety is improved, but user convenience for battery replacement decreases

Engineering Contradiction:

Improvesafety from battery swallowingVSAvoidconvenience of battery replacement

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The opening mechanism is segmented into two functional parts: a hole in the main body for tool insertion, and a fastening part on the cover that requires pressing. This segmentation allows the cover to remain securely attached during normal use while enabling easy separation when the appropriate tool is used.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The design allows users to serve themselves by using a simple external tool (such as a pen or stick) that is readily available, eliminating the need for specialized opening tools or complex mechanisms while maintaining safety.

Inventive Principle:

Principle #25Self-service

3Object-affected harmful factors

If a secure fastening mechanism is used to prevent accidental opening, then safety is improved, but the complexity of the device increases

Engineering Contradiction:

Improveaccidental cover separationVSAvoidcover fastening structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The fastening function is extracted from the cover itself and relocated to interact through a hole in the main body. The fastening part extends into the main body and can be pressed through the hole, separating the locking function from the cover structure and simplifying the overall design.

Inventive Principle:

Principle #2Taking out (Extraction)
