Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light source is added to illuminate the display window and input means, then readability and operability are improved, but device complexity and power consumption increase
Solution Approach 1:
The patent combines multiple functions into the housing structure: the housing serves both as the structural enclosure and as the mounting platform for the light source, display window, and input means. This integration reduces the need for separate components and simplifies the overall device architecture while maintaining improved readability and operability.
Solution Approach 2:
The patent introduces a light guide as an intermediary element between the light source and the display window/input means. The light guide efficiently distributes light from the source to illuminate the display area and input means, improving readability without requiring the light source to be in direct contact with these elements, thus maintaining design flexibility and reducing complexity.
2Illumination intensity
If a light source is added to illuminate the display window and input means, then readability and operability are improved, but power consumption increases
Solution Approach 1:
The light source is designed to operate in periodic cycles rather than continuously. It illuminates the display window and input means during active use periods when the device is being operated, then enters low-power states during idle periods. This periodic operation significantly reduces overall power consumption while maintaining adequate illumination when needed for readability and operability.
Solution Approach 2:
The illumination is provided locally only to the specific areas that need it - the display window and input means - rather than illuminating the entire device. This localized approach minimizes the total light output required and consequently reduces power consumption while still achieving the goal of improved readability and operability where it matters most.
3Duration of action of moving object
If the light source illuminates only during operation, then battery life is extended, but readability during setup may be insufficient
Solution Approach 1:
The light source is activated in advance during the setup phase before actual device operation begins. This preliminary illumination ensures that users can clearly see and configure device settings, adjust parameters, and understand input options before starting to use the device. After setup is complete, the light source enters periodic operation mode to extend battery life during normal use.
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 solution provides enhanced readability and operability, especially for visually impaired users, by ensuring clear display of dosage information and operational states, reducing the risk of misreading and extending battery life through efficient lighting.
Implementation Method 1
The medication delivery device comprises a light guide which is arranged in the optical path between the light source and the at least partially transparent window
Implementation Method 2
LCD-panels are fabricated as transparent substrates with polarization changing liquid crystals in between and illumination of the LCD-panel can be performed from the backside by the light source
Implementation Method 3
the light source comprises at least two light emitting elements, preferably light-emitting diodes, capable of emitting light with different colors
