Adjustable Robot Arm Hands for Window Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot arms for transferring windows require multiple versions to accommodate different sizes, leading to increased manufacturing and replacement costs, time, and defects such as cracks and static electricity issues due to residual pressure and contact with the folding area during transfer.
Innovation Solution
A robot arm design featuring adjustable distance between first and second hands with engraved patterns and an auxiliary member, which allows for vacuum suction without contact with the folding area, reducing the need for multiple robot arm versions and minimizing defects by discharging residual pressure and static electricity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple versions of robot arms are used to accommodate different window sizes, then transfer precision for various sizes is improved, but manufacturing cost and device complexity increase
Solution Approach 1:
The robot arm incorporates an adjustable distance mechanism between the first and second hands, allowing the configuration to be dynamically changed according to different window sizes. This enables a single robot arm to adapt to multiple transfer scenarios without requiring multiple fixed-version arms, thereby reducing device complexity while maintaining transfer precision.
Solution Approach 2:
The robot arm is designed with universal functionality to handle various window sizes through the adjustable distance feature. Instead of requiring separate specialized arms for different sizes, this single multi-functional arm can be reconfigured for different transfer requirements, reducing manufacturing costs and simplifying the overall system.
2Adaptability or versatility
If multiple versions of robot arms are used to accommodate different window sizes, then adaptability to different sizes is improved, but manufacturing cost increases
Solution Approach 1:
The adjustable distance mechanism allows the robot arm to adapt to different window sizes without requiring multiple specialized versions. This dynamic reconfiguration capability maintains high adaptability while significantly reducing manufacturing costs by eliminating the need to produce and store multiple robot arm variants.
Solution Approach 2:
The robot arm's configuration parameters (distance between hands) can be changed according to different transfer requirements. This parameter adjustability provides the needed adaptability for various window sizes without the expense of manufacturing multiple fixed-parameter arms.
3Ease of operation
If the robot arm contacts the folding area during transfer, then handling simplicity is improved, but defect rate increases
Solution Approach 1:
The engraved patterns are selectively positioned on specific local areas of the hands (first and second hands) rather than covering the entire surface. This local modification allows the robot arm to maintain simple vacuum suction handling while the engraved patterns specifically prevent contact with the folding area, thereby reducing defects without compromising handling simplicity.
4Speed
If vacuum suction is applied without considering residual pressure, then transfer speed is improved, but defect rate increases
Solution Approach 1:
The engraved patterns create porous or channel-like structures on the hand surfaces that allow residual pressure to escape during vacuum suction. This enables rapid transfer speeds to be maintained while the engraved channels actively manage pressure release, preventing defects caused by trapped residual pressure.
