Conventional thickness measuring devices for laminating films have limited measurement accuracy due to the precision and resolution of their components and sensors, leading to increased costs when higher accuracy is required.
Innovation Solution
A thickness measuring device design that incorporates a linking component with a rotating element, where the distance between the first moving component and the rotating axis is shorter than the distance between the second moving component and the rotating axis, amplifying the displacement of the second moving component to enhance sensing signal amplification and measurement accuracy, while maintaining a cost-effective structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the precision of components and resolution of sensor are increased to improve measurement accuracy, then measurement accuracy is improved, but device cost is raised
Solution Approach 1:
The patent introduces a linking component with a rotating element as an intermediary mechanism between the first moving component and the second moving component. This mediator amplifies the displacement of the sensing element through its rotating element, which has different distance relationships with the rotating axis for the two connection portions. This allows measurement accuracy improvement without requiring higher precision components or higher resolution sensors, thus avoiding increased device cost.
2Measurement precision
If the displacement of sensing element is enlarged to improve measurement accuracy, then measurement accuracy is improved, but device complexity is increased
Solution Approach 1:
The patent transforms the linear displacement relationship into a rotational dimension. The linking component's rotating element converts the linear movement of the first moving component into rotational movement, which then translates to amplified linear movement of the second moving component. This dimensional transformation achieves displacement amplification without adding complex multi-axis mechanisms, maintaining relative structural simplicity.
3Device complexity
If a fixed grating is directly connected to detection rod to measure thickness, then device structure is simple, but measurement accuracy is limited
Solution Approach 1:
The patent replaces the static direct connection between the fixed grating and detection rod with a dynamic linking component system. The linking component with its rotating element introduces dynamic motion transformation, converting small linear displacements into amplified displacements. This dynamic mechanism maintains structural simplicity while significantly improving measurement accuracy through motion amplification.
