Solution Overview

Problem

Portable bioparameter determining devices are bulky due to their design, which occupies unnecessary storage space when not in use and allows ambient light to interfere with the measurement process.

Innovation Solution

A space-saving structural component with a grooved recess and a flexible, flat cover that deforms elastically to accommodate an appendage, sealing the chamber and optimizing the device's operation by isolating light when the appendage is present, and returning to a compact state when absent, ensuring efficient use of storage space and minimizing ambient light interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a chamber is designed to receive an appendage in a portable bioparameter determining device, then the device can perform non-invasive measurements, but the device becomes bulky and occupies unnecessary storage space when not in use

Engineering Contradiction:

Improvenon-invasive measurement capabilityVSAvoiddevice volume

Core Design Contradiction:

Ease of operationVSVolume of moving object

Solution Approach 1:

The cover is designed to be movable between an open position (allowing appendage insertion) and a closed position (creating a compact profile). This dynamic structure allows the chamber volume to change based on operational needs, reducing the device volume when not in use while maintaining measurement capability when needed.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The appendage is inserted into a recess that is integrated within the device structure, with the cover closing over it. When closed, the appendage-containing recess is nested within the overall device footprint, effectively reducing the external volume occupied by the device while preserving the internal measurement chamber.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Ease of operation

If a chamber is designed to receive an appendage, then measurements can be taken, but ambient light interferes with the measurement process

Engineering Contradiction:

Improvemeasurement capabilityVSAvoidambient light interference

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The closed cover creates an optically controlled environment within the chamber, isolating the measurement area from ambient light. This effectively creates an 'inert' optical atmosphere where only the light from the light source interacts with the appendage, eliminating harmful ambient light interference during measurements.

Inventive Principle:

Principle #39Inert atmosphere (Inert environment)

3Object-affected harmful factors

If a flexible cover is used to accommodate the appendage, then the device can seal the chamber to isolate light, but the cover must deform elastically which requires additional space

Engineering Contradiction:

Improvelight isolationVSAvoidcomponent volume

Core Design Contradiction:

Object-affected harmful factorsVSVolume of moving object

Solution Approach 1:

The cover is made of flexible material that can deform elastically to accommodate the appendage while maintaining a compact form factor. This flexible shell approach allows the cover to conform to the appendage shape when inserted, creating effective light isolation without requiring a large rigid chamber structure.

Inventive Principle:

Principle #30Flexible shells and thin films
