Electronic Pipette Touch Screen Interface Ergonomics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic pipettes often cause user fatigue due to fixed and non-adaptive user interfaces, which can lead to increased physical stress during operation, as they do not accommodate varying hand sizes or user preferences effectively.
Innovation Solution
The implementation of touch screens with adjustable and programmable icons and areas for controlling pipetting operations, allowing for customizable operation and real-time feedback, along with sliding functions that mimic manual pipetting motions, to reduce user strain and improve ergonomic compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fixed user interface buttons are used for controlling pipetting operations, then the device structure is simple, but user fatigue increases due to non-adaptive interface that does not accommodate varying hand sizes or user preferences
Solution Approach 1:
The patent implements a touch screen interface where button positions, sizes, and configurations can be dynamically adjusted based on user preferences, hand size, and operational context. The interface transitions from static fixed buttons to dynamic customizable elements, allowing users to optimize the interface for their specific needs and reduce fatigue during prolonged use.
Solution Approach 2:
The system allows modification of interface parameters including button position coordinates, button size dimensions, and operational settings. These parameters can be changed to accommodate different users and operational scenarios, transforming the rigid fixed interface into an adaptable one that responds to user requirements.
2Adaptability or versatility
If fixed button locations are used on the user interface, then the device is easier to manufacture, but adaptability to different users and operations is reduced
Solution Approach 1:
The touch screen interface employs dynamic button positioning and sizing capabilities, allowing the same physical device to adapt to different users and operational requirements. This software-based adaptability achieves versatility without requiring multiple physical device variants, maintaining manufacturing simplicity while enhancing user accommodation.
Solution Approach 2:
The single touch screen interface serves multiple functions and accommodates multiple user types through programmable button configurations. The system can be programmed to provide different interface layouts for different users or operations, making one device universally adaptable rather than requiring specialized versions for different use cases.
3Ease of operation
If standard fixed-size touch areas are used, then the device design is simpler, but ease of operation is reduced for users with different hand sizes
Solution Approach 1:
The system allows modification of touch area size parameters to accommodate different hand sizes and user preferences. Users can adjust the dimensions of clickable areas on the touch screen to make them appropriately sized for their comfort, transforming uniform fixed-size buttons into customizable variable-size interactive elements.
Solution Approach 2:
Different regions of the touch screen can have different button sizes and configurations optimized for specific operations or user needs. The interface allows local customization where frequently used buttons for a particular user can be larger or positioned in easily reachable areas, while maintaining overall system functionality.
