Solution Overview

Problem

Existing injection devices are complex and difficult for users with disabilities or older individuals to operate due to text-based instructions and numerous buttons, and their ergonomic design is unsuitable for comfortable handling.

Innovation Solution

A pen-like injection device with an ergonomic gripping surface, featuring display elements on both the lateral and rear ends, using luminous pictograms and LEDs to guide users through the injection process, ensuring readability and usability regardless of language or visibility during use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If text-based display instructions are used on the front surface, then information can be conveyed to users, but readability becomes difficult for users with disabilities due to text size and reflections

Engineering Contradiction:
Improveinformation conveyanceVSAvoidreadability for users with disabilities
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent uses color-coded pictograms instead of text to convey information. Different colors represent different states or instructions, making the display readable and interpretable for users with visual impairments or reading difficulties, while still effectively communicating the necessary information.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent replaces complex text instructions with simplified visual symbols and icons that copy or represent the essential meaning of the text in a more accessible format. This allows users to quickly understand instructions without needing to read or interpret text.

Inventive Principle:
Principle #26Copying

2Adaptability or versatility

If numerous buttons are provided for device operation, then device functionality and control options increase, but operation becomes a real challenge for older people who have not grown up with electronic devices

Engineering Contradiction:
Improvedevice functionalityVSAvoidoperational simplicity for older users
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent removes the need for multiple physical buttons by extracting the control function and replacing it with a push-buttonless interface. Users simply press the injection button, and the device handles all other operations automatically, eliminating the complexity of navigating numerous buttons while maintaining full device functionality.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The device performs operations automatically without requiring users to manually control multiple buttons. The system self-manages the injection process, eliminating the need for users to navigate complex button interfaces while preserving all necessary device functions.

Inventive Principle:
Principle #25Self-service

3Stability of the object's composition

If a box-shaped housing is used for the injection device, then structural stability is provided, but holding the device during injection is either simply unpleasant or, depending on the disposition of a user, almost impossible

Engineering Contradiction:
Improvestructural stabilityVSAvoidergonomic comfort during injection
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent transitions from a box-shaped housing to a pen-like shape with curved surfaces that conform to the natural contours of the hand. This ergonomic design provides structural stability while enabling comfortable and intuitive gripping during injection, accommodating various user hand dispositions.

Inventive Principle:
Principle #14Spheroidality (Curvature)

4Loss of information

If the display screen is arranged on the wide front surface, then information can be displayed to guide users, but the text displayed can be difficult for the user with a disability to read due to size and reflections

Engineering Contradiction:
Improveinstruction displayVSAvoidreadability under various lighting conditions
Core Design Contradiction:
Loss of informationVSIllumination intensity

Solution Approach 1:

The patent uses color-coded visual indicators that are visible under various lighting conditions. The color changes provide clear visual feedback that is readable regardless of ambient light, eliminating reflection issues while maintaining effective information display.

Inventive Principle:
Principle #32Color changes
