Insulin Pump Bistable Display for Low-Power Status Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional insulin therapy methods, including insulin pumps, often require multiple daily injections and complex tracking, and insulin pumps can be difficult to program, leading to inconvenience and potential insulin level variations, which can result in serious health complications for diabetic patients.
Innovation Solution
The development of an insulin pump device featuring a bistable display that requires minimal power to maintain images, a processor to display non-blank screens when no input is received, and customizable menus and color indicators to assist users in effectively managing their therapy, along with alternative display systems for training and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a conventional display is used in the insulin pump, then the display can show information to the user, but the display consumes excessive power and requires constant refreshing
Solution Approach 1:
The patent applies periodic action by using a bistable display that maintains its state without continuous power input. The display only consumes power when transitioning between states (writing mode) and remains stable during readout mode, eliminating the need for constant refreshing and dramatically reducing power consumption while maintaining reliable display functionality.
Solution Approach 2:
The patent replaces the conventional electronic display system that requires continuous power for refreshing with a bistable display technology that uses a different mechanism (such as electrophoretic or interferometric modulation) to maintain visual output without continuous energy input, thus solving the power consumption issue while preserving display reliability.
2Use of energy by moving object
If the insulin pump display shows static information, then power consumption is reduced, but user engagement and attention to critical information decreases
Solution Approach 1:
The patent uses periodic action by implementing animated sequences that automatically play for a limited duration when the pump is idle. The animation cycles through multiple display states or visual elements in sequence, then pauses, allowing user interaction to resume. This periodic animation maintains user engagement and draws attention to critical information without requiring continuous power consumption, as the animation only operates during idle periods.
Solution Approach 2:
The patent applies dynamics by enabling the display to transition between static power-saving mode and animated engaging mode based on user interaction and system state. The display dynamically adjusts its behavior - remaining static when idle to conserve power, then activating animated sequences to engage users when needed, thus balancing power consumption with user engagement requirements.
3Adaptability or versatility
If the insulin pump has complex programming options, then therapy customization is improved, but device complexity and difficulty of programming increases
Solution Approach 1:
The patent applies dynamics by implementing a adaptive user interface that automatically adjusts its complexity based on the user's needs and interactions. The system starts with simplified guidance for new users, progressively revealing more advanced programming options as users become more comfortable with the device. This dynamic adaptation allows comprehensive therapy customization to be available while reducing the perceived complexity for average users.
Solution Approach 2:
The patent uses feedback mechanisms in the form of guided programming modes that provide real-time instructions and validation during the programming process. The system gives step-by-step guidance, confirms user inputs, and adjusts the interface based on user progress and errors, thereby enabling complex therapy customization while reducing the difficulty of programming through structured feedback loops.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The insulin pump device enhances user convenience and safety by reducing power consumption, providing customizable and animated displays, and offering intuitive menu navigation, thereby improving insulin management and reducing the risk of complications.
Implementation Method 1
A display element of the bistable display is placed in one of two stable orientations upon application of a biasing voltage. The display element stays in the stable orientation when the biasing voltage is removed.
