Solution Overview

Problem

Existing automated liquid handling systems lack a robust and efficient mechanism for quickly attaching, adjusting, and removing modules from actuating devices, limiting flexibility and precision in liquid handling operations.

Innovation Solution

A self-centering mounting system comprising a base plate, a locking mechanism with a groove and a locking part, and an adjustably attached mounting rail, allowing for rapid adjustment and secure locking of modules relative to the base plate of a manipulator.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a robust attachment mechanism is used to securely mount modules, then reliability of attachment is improved, but speed of attachment and adjustment deteriorates

Engineering Contradiction:
Improveattachment securityVSAvoidattachment time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The locking mechanism transitions between locked and unlocked states through rotational movement of the locking shaft, enabling rapid attachment and detachment without complex manual operations. The dynamic state change allows secure mounting when locked and quick release when unlocked.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The locking part is separated from the mounting rail, allowing the rail to be independently positioned and adjusted before locking. This extraction enables the rail to be moved freely in the open position and then securely fixed when locked.

Inventive Principle:
Principle #2Taking out (Extraction)

2Stability of the object's composition

If modules are firmly fixed to the base plate, then positional stability is improved, but adjustability and flexibility deteriorate

Engineering Contradiction:
Improvepositional stabilityVSAvoidadjustability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The mounting system allows the rail to transition between movable and fixed states. When the locking mechanism is in the open position, the rail can be freely adjusted to different positions. When locked, the rail becomes firmly fixed, providing positional stability during operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The mounting system is divided into separate components: the base plate, the locking mechanism, and the mounting rail. This segmentation allows the rail to be independently positioned and adjusted before being locked to the base plate, enabling both adjustability and stability.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If multiple modules are mounted on the manipulator, then functionality and versatility are improved, but device complexity increases

Engineering Contradiction:
Improvefunctional versatilityVSAvoidmounting system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The locking mechanism and mounting rail design allows multiple modules to be mounted on the manipulator using the same standardized interface. Each module can be independently attached and adjusted using identical locking mechanisms, simplifying the overall system despite increased functionality.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The mounting system uses modular components that can be independently assembled and configured. Each module has its own locking mechanism that operates independently, allowing multiple modules to be mounted without increasing the complexity of individual mounting operations.

Inventive Principle:
Principle #1Segmentation
