Camera-equipped screwing device for ergonomic operator guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of screwing devices often adopt ergonomically unfavorable postures to access and see difficult-to-reach screwing points, leading to uncomfortable and time-consuming processes, potentially causing poor posture over time.
Innovation Solution
A screwing device equipped with a camera device that films the screwing point and transmits real-time images to a display, allowing the operator to perform the screwing process in an ergonomically favorable posture by acting as a virtual eye, combined with a holding mechanism providing translational and rotational degrees of freedom to absorb forces and torques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operator directly observes the screwing point, then the screwing operation can be performed with direct visual feedback, but the operator must adopt ergonomically unfavorable postures to access difficult-to-reach points
Solution Approach 1:
The patent uses a camera device to create a visual copy (image) of the screwing point and transmits it to a display device. This allows the operator to view the screwing point indirectly through the displayed image rather than directly observing it, enabling ergonomic positioning while maintaining visual feedback capability.
2Ease of operation
If a camera device is added to film the screwing point, then ergonomic posture is improved, but the device complexity increases
Solution Approach 1:
The camera device is integrated into the screwing device to serve multiple functions: it films the screwing point for ergonomic viewing, and can also save the filmed images for quality control purposes. This multi-functionality justifies the added complexity by providing both ergonomic benefits and quality assurance capabilities.
3Difficulty of detecting and measuring
If real-time image transmission is implemented, then the operator can follow the screwing process virtually in real time, but the loss of time for image processing and transmission occurs
Solution Approach 1:
The system establishes a feedback loop where the camera device continuously captures images of the screwing point and transmits them in real-time to the display device. This allows the operator to monitor the screwing process with minimal delay, maintaining effective visual feedback for precise operation control.
