Manual Dosing Device Segmented Frame Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional manual dosing devices have a rigid housing that does not fit well in the hand, becomes dirty easily, and is difficult to clean, limiting the selection of materials and user comfort.
Innovation Solution
A manual dosing device with a long, elongated frame as a support structure that holds the syringe or pipette tip at its bottom end, with drive means attached above, and a housing that is only partially supported by the frame to absorb forces, allowing for a soft and easily cleanable housing material with improved haptics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid housing is used to support all components, then structural strength is improved, but user comfort and ease of cleaning deteriorate
Solution Approach 1:
The support structure is segmented into a rigid frame (providing structural strength) and a separate housing (providing user comfort and ease of cleaning). The frame carries the mechanical loads while the housing can be made of soft, easily cleanable material that contacts the user's hand.
Solution Approach 2:
The load-bearing function is extracted from the housing and assigned to a dedicated rigid frame. This allows the housing to be optimized for user comfort and hygiene without compromising structural strength.
2Strength
If a rigid housing is used to support all components, then structural strength is improved, but ease of cleaning deteriorates
Solution Approach 1:
The device is segmented into a rigid frame for structural strength and a separate housing for ease of cleaning. The housing can be made of smooth, non-porous material that is easy to wipe clean, while the frame provides the necessary structural support.
Solution Approach 2:
The cleaning-related functions are extracted from the structural support system. The housing, which requires ease of cleaning, is separated from the frame, allowing independent optimization of both properties.
3Device complexity
If a rigid housing supports all components, then device complexity is reduced, but material selection flexibility deteriorates
Solution Approach 1:
The support system is segmented into frame and housing, allowing different materials to be selected for each component based on their specific functional requirements. The frame uses rigid materials for strength, while the housing uses materials optimized for user comfort and hygiene.
Solution Approach 2:
The frame serves as a universal load-bearing structure that can support various configurations of dosing components, while the housing can be customized with different materials and designs to meet specific user comfort and hygiene requirements.

AI summary
A manual dosing device for dosing liquids on which a syringe or pipette tip can be releasably held. The manual dosing device includes an elongated frame as a support structure, a mechanism for releasably holding a syringe or pipette tip at the bottom end of the frame, a drive member that attached above the mechanism for releasably holding to the frame, a displacement member for displacing a fluid in the syringe or pipette tip that can be driven by the drive means and are connected to the mechanism for releasably holding, and a housing encasing the frame.
