Electronic Pipette Two-Axis Controller Usability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic pipettes are less favored than manual pipettes due to their increased complexity, higher cost, unreliability, and difficulty in use, despite offering advanced features and ergonomic benefits, as they are often larger, heavier, and less intuitive.
Innovation Solution
A lightweight, reliable electronic pipette with a large color dot-matrix display, multifunction control buttons, and a two-axis controller for improved user experience, along with a micro-USB socket for charging and remote control, and an RFID tag for tracking and compliance, addressing ergonomic and usability issues while maintaining advanced features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electronic components (battery, control circuit, drive motor) are added to create an electronic pipette, then advanced features and ergonomic benefits are achieved, but the pipette becomes larger and heavier
Solution Approach 1:
The controller serves multiple functions: it acts as a directional control for navigation through menus and settings, a selection mechanism for choosing options, and a confirmation button when depressed. This multi-functionality reduces the need for separate buttons and controls, thereby minimizing the electronic component count and overall weight while maintaining advanced features
2Adaptability or versatility
If electronic components are added to create an electronic pipette, then advanced features are achieved, but the pipette becomes more complex and expensive
Solution Approach 1:
The controller integrates multiple control functions into a single component, reducing the total number of electronic parts needed. The color display serves as both an information output device and an interactive interface element. This consolidation reduces electronic complexity while maintaining advanced features like multidispense modes and complex sequences
Solution Approach 2:
The color display provides real-time visual feedback to the user, showing current settings, operational status, and guiding the user through menu structures. This feedback mechanism simplifies the user interface by providing intuitive visual cues, reducing the need for complex button combinations and making the electronic pipette easier to use despite its advanced capabilities
3Volume of moving object
If a small monochromatic display and few buttons are used due to size and cost constraints, then the pipette remains compact, but the user interface becomes difficult to program and use
Solution Approach 1:
The color display uses different colors to indicate various states, modes, and input fields, providing intuitive visual feedback without requiring additional display real estate. Colors help users quickly understand the current state and navigate the interface, significantly improving ease of use while maintaining a compact form factor
Solution Approach 2:
The controller functions as a directional pad for navigating menus, a selection mechanism for choosing options, and a confirmation button when depressed. This multi-functional design provides a rich user interface experience comparable to much larger devices, while keeping the physical footprint small and the pipette compact
4Ease of operation
If a large color display and multiple control buttons are added, then user friendliness and graphical feedback are improved, but the pipette becomes heavier and more complex
Solution Approach 1:
The controller serves multiple functions including directional control, option selection, and confirmation, eliminating the need for numerous separate buttons. This reduces the electronic component count and overall weight while maintaining an intuitive and friendly user interface with ample control options
