Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If multiple contact points or surfaces are used to support the rotational shaft, then the structural stability is improved, but the rotational resistance increases
Solution Approach 1:
The support structure is segmented into a fixed support part and a movable support part, with the connection part bridging them. This segmentation allows the rotational shaft to be supported at multiple locations while minimizing contact at the critical rotation interface, thus maintaining stability without excessive rotational resistance.
Solution Approach 2:
The connection part acts as an intermediary between the fixed support part and the movable support part. It provides the necessary structural linkage while allowing relative movement, thereby supporting the rotational shaft without creating excessive friction or rotational resistance at the support interface.
2Strength
If multiple contact points or surfaces are used to support the rotational shaft, then the mechanical strength is improved, but the measurement precision deteriorates
Solution Approach 1:
By segmenting the support system into fixed and movable parts connected by the connection part, the invention maintains mechanical strength through distributed support while minimizing contact at the rotation interface. This reduces frictional forces that would otherwise interfere with the precise measurement of angular displacement.
Solution Approach 2:
The connection part serves as an intermediary that transmits structural support forces while allowing smooth relative movement between the fixed and movable support parts. This intermediary function preserves mechanical strength without introducing excessive friction that would compromise measurement precision.
3Stability of the object's composition
If multiple contact points or surfaces are used in the support structure, then the structural stability is improved, but the frictional force increases
Solution Approach 1:
The support structure is divided into distinct fixed and movable parts with a connection part between them. This segmentation concentrates the necessary contact at specific interfaces while minimizing contact at the rotation point, thereby maintaining stability without generating excessive frictional force.
Solution Approach 2:
The connection part functions as an intermediary element that provides structural linkage between the fixed and movable support parts while facilitating smooth relative movement. This intermediary role maintains structural stability without creating excessive friction that would impede rotation.
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
The solution significantly reduces rotational resistance, enhancing the sensitivity and accuracy of thrombelastography measurements by minimizing frictional forces, allowing for more precise blood coagulation analysis.
Implementation Method 1
Since the first fixing connection member and the second fixing connection member are connected together in point contact fashion, when the movable support part rotates relative to the fixed support part, only one contact point generates a frictional force to impede the rotation of the movable support part.
