Scan Head Rotation Mechanism for Ergonomic Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dataform scanning devices with a single rotational pivot point compromise either side scanning or front scanning ergonomics, leading to user fatigue during intensive applications due to suboptimal ergonomic adjustments.
Innovation Solution
A scan head mechanism that rotates and mechanically adjusts the scan engine angle using a cam assembly with a rotating cam pin and adjustable cam height, allowing for optimal ergonomic positioning through a predetermined cam path, enabling multiple ergonomic angles and adjustable settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single rotational pivot point scan head is used, then the device complexity is reduced, but the ergonomics for either side scanning or front scanning is compromised, leading to user fatigue
Solution Approach 1:
The scan head is divided into multiple independent rotational segments, each capable of rotating about its own pivot point. This segmentation allows the scan head to achieve multiple ergonomic configurations for different scanning modes (side scanning, front scanning, angled scanning) without requiring a completely complex redesign, as each segment can be optimized independently
Solution Approach 2:
The scan head incorporates dynamic rotational mechanisms that allow real-time adjustment of scanning angles and orientations. The multiple pivot points enable the scan head to dynamically adapt its position and angle during operation, providing optimal ergonomics for various scanning scenarios rather than being fixed in a single configuration
2Device complexity
If the scan head is fixed at a single angle, then the device complexity is minimized, but the adaptability to different scanning modes is reduced
Solution Approach 1:
The scan head employs dynamic rotational mechanisms with multiple pivot points that enable real-time adjustment of scanning angles. Each rotational segment can be independently positioned to accommodate different scanning modes (side scanning, front scanning, angled scanning), providing adaptability without requiring an overly complex mechanism
Solution Approach 2:
The multi-pivot scan head design serves multiple scanning functions through a single integrated mechanism. The same rotational segments and pivot points enable various scanning modes and angles, making the device versatile for different applications without requiring separate mechanisms for each function

AI summary
A scan head adjustable for optimum ergonomic scan angles. The scan head can be rotated according to a user's preferred mode such that the angle of the scan engine can be mechanically adjusted to give the optimum angle for its use. In support thereof, a cam provides sufficient action to give the optimum angle. A rotating cam pin is utilized through the cam path in accordance with a predetermined height that adjusts to specific angles of the scan engine.
