Ergonomic Pipette Handle with Flexible Finger Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipettes lack ergonomic flexibility and tactile comfort, as they do not adapt to individual hand shapes, leading to suboptimal grip and manual handling during liquid dispensing.
Innovation Solution
A pipette with a flexible finger support made of elastic material, featuring a pivoted tip part and a spring that presses the tip part towards the handle, allowing users to shape the finger rest for optimal comfort and including a detachable elastic part and a lower radial support for improved grip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rigid finger support is used, then structural stability is maintained, but ergonomic adaptability and tactile comfort deteriorate
Solution Approach 1:
The finger support is designed with a spring mechanism that allows it to dynamically adapt to different finger pressures and shapes. The spring enables the support to move and conform to the user's finger while maintaining structural integrity through its elastic properties.
Solution Approach 2:
The finger support utilizes elastic material properties to change its physical state between compressed and relaxed positions. This parameter change allows the support to adapt ergonomically while the material's inherent elasticity maintains structural stability.
2Ease of operation
If a flexible finger support is used, then ergonomic comfort is improved, but structural stability deteriorates
Solution Approach 1:
The finger support employs an elastic material that functions as a flexible element, allowing it to conform to the user's finger for improved tactile comfort. The flexible nature of the elastic material provides the necessary adaptability while maintaining sufficient structural support.
Solution Approach 2:
The spring-loaded mechanism creates a dynamic system where the finger support can flex and adapt to different finger shapes and pressures, providing tactile comfort while the spring's restoring force maintains structural stability.
3Adaptability or versatility
If a fixed finger support design is used, then manufacturing simplicity is maintained, but user customization and ergonomic optimization deteriorate
Solution Approach 1:
The spring mechanism allows the finger support to dynamically adjust to different user needs without requiring multiple fixed designs. This single dynamic component provides customization capability while maintaining manufacturing simplicity through standardized spring and elastic material production.
Solution Approach 2:
The elastic material and spring mechanism enable parameter changes in the finger support's position and shape based on user interaction, providing customization without requiring complex manufacturing processes. The standard elastic materials and spring components keep manufacturing simple.
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
Enhances ergonomic fit and reduces manual effort required for handling, providing a customizable grip that improves tactile comfort and operational efficiency during liquid dispensing.
Implementation Method 1
a spring that presses the tip part towards the handle
Implementation Method 2
a spring that presses the tip part towards the handle
Implementation Method 3
the flexible support element is positioned substantially in the lengthwise direction of the handle... the user may shape the finger rest to be optimally suitable for him/her
