Handheld Processing Device Transport Eyelet Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-held processing devices are not user-friendly for comfortable carrying and operation, as they often require two hands and complex securing mechanisms, which can lead to obstruction and difficulty in handling.
Innovation Solution
A hand-held processing device design featuring a handle with a transport eyelet arranged along the longitudinal axis, allowing for one-handed carrying and operation, with a secure and easy-to-use securing mechanism that includes a carabiner hook or similar device, enabling quick attachment and detachment without obstructing the device's operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional securing mechanism is used, then the device can be carried securely, but it requires two hands and complex operations that reduce ease of operation
Solution Approach 1:
The handle is divided into two functional sections: a main handle for gripping and a separate transport eyelet for securing. This segmentation allows the carrying function to be separated from the operating hand, enabling one-handed operation while maintaining secure transport capability.
Solution Approach 2:
The transport eyelet is extracted as a separate component from the main handle body. It can be positioned independently along the longitudinal axis, allowing it to be engaged or disengaged without interfering with the main handle's gripping function, thus simplifying the overall securing mechanism.
2Ease of operation
If the transport eyelet is positioned incorrectly, then the device can be secured, but it obstructs the handle opening and reduces ease of operation
Solution Approach 1:
The transport eyelet is positioned at a specific location along the longitudinal axis where it does not interfere with the handle opening. This localized positioning ensures that the eyelet serves its securing function while maintaining clear access to the handle opening for operational purposes.
Solution Approach 2:
The handle opening is designed with an asymmetric orientation relative to the transport eyelet position. The handle opening extends in a direction that is offset from the longitudinal axis, ensuring that even when the eyelet is present, it does not symmetrically block the asymmetrically oriented handle opening.
3Ease of operation
If the handle opening is not aligned with the longitudinal axis, then the device can be operated comfortably, but it reduces manufacturing precision
Solution Approach 1:
The handle opening's longitudinal axis is merged with the device's main longitudinal axis. By aligning both axes, the design achieves both comfortable operation (as the handle naturally follows the device axis) and manufacturing precision (as a single reference axis simplifies production alignment).
