Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing substrate-holding apparatuses face challenges in setting the pitch between blades at a desired value due to deviations in blade attachment, requiring time-consuming and labor-intensive fine adjustments.
Innovation Solution
A substrate-holding hand and substrate-conveying robot design that utilizes an eccentric element to connect each blade to a support mechanism, allowing for easy fine adjustment of the pitch between blades by changing the rotation angle of the eccentric element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If blade attachment plates are attached to a pitch conversion cylinder to change the pitch between blades, then the pitch can be adjusted, but deviation in attachment occurs making fine adjustment difficult and time-consuming
Solution Approach 1:
The patent changes the parameter of blade positioning from fixed attachment plate locations to continuously adjustable positions via eccentric elements. By rotating the eccentric elements, the vertical positions of blades can be precisely adjusted to achieve the desired pitch, eliminating attachment deviation issues and enabling quick fine adjustments without time-consuming manual intervention.
2Adaptability or versatility
If blade attachment plates are used to change pitch, then pitch adjustment is possible, but the adjustment process requires significant work activity and effort
Solution Approach 1:
The patent replaces the complex mechanical attachment plate system with a simpler eccentric element mechanism. The eccentric elements convert rotational motion into vertical displacement, allowing blades to be easily positioned at different heights. This substitution dramatically simplifies the adjustment operation, making it intuitive and requiring minimal effort while maintaining full adaptability for pitch adjustment.
3Adaptability or versatility
If pitch conversion cylinder moves blade attachment plates to change pitch, then pitch variation is achieved, but attachment deviation prevents desired pitch setting
Solution Approach 1:
The patent introduces dynamic adjustability through rotatable eccentric elements, transforming the static attachment plate system into a dynamically adjustable mechanism. Each blade's position can be independently fine-tuned by rotating its corresponding eccentric element, allowing precise achievement of the desired pitch within the full variation range while eliminating the attachment deviation problems inherent in fixed-position systems.
