Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional substrate conveying hands with frames and blades have a wide frame that is not optimally utilized for rigidity, making it difficult to reduce the frame width while maintaining mechanical strength, which complicates component arrangement and maintenance.
Innovation Solution
A substrate holding hand with a frame and blade configuration where the frame, front supports, and rear supports are arranged in a V-shape, allowing for a reduction in frame width while maintaining rigidity and enabling easier component arrangement and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the frame width is increased to ensure rigidity, then the mechanical strength is improved, but the space for component arrangement and maintenance is reduced
Solution Approach 1:
The patent applies asymmetry by configuring the frame, front supports, and rear supports in a V-shape rather than a symmetric rectangular structure. This asymmetric arrangement optimizes the distribution of structural members to provide maximum rigidity with minimum material, allowing the frame width to be reduced while maintaining mechanical strength.
Solution Approach 2:
The patent transitions from a two-dimensional rectangular frame structure to a three-dimensional V-shaped configuration. By utilizing spatial arrangement in multiple dimensions, the structure achieves enhanced rigidity through the geometric configuration rather than simply increasing frame width, thus solving the contradiction between strength and compactness.
2Area of stationary object
If the frame width is reduced to save space, then the component arrangement space is improved, but the rigidity is reduced
Solution Approach 1:
The V-shaped asymmetric configuration allows the frame to achieve optimal rigidity with reduced width by strategically positioning structural members along the V-shape, rather than uniformly distributing them in a wider rectangular frame.
Solution Approach 2:
The patent changes the geometric parameters of the frame structure from a rectangular configuration to a V-shaped configuration. This parameter change optimizes the structural efficiency, allowing the frame to maintain rigidity while reducing the overall width and creating more space for components.
3Ease of operation
If the frame width is increased to simplify component arrangement, then the ease of operation is improved, but the space utilization is reduced
Solution Approach 1:
By transitioning to a three-dimensional V-shaped configuration, the patent creates efficient spatial arrangement for components along the angled members of the V-shape. This allows components to be arranged in a compact yet accessible manner, maintaining ease of operation while minimizing the overall frame width.
