Mobile computing devices used as barcode readers in transport and logistics facilities often require a handle for efficient scanning, but existing solutions do not facilitate easy attachment and detachment, and alignment with the ground for optimal scanning.
Innovation Solution
A handle adapter with a biased latch and switch mechanism that allows secure attachment and easy release of the mobile computing device, enabling efficient scanning by aligning the device parallel to the ground.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a mobile computing device is held in hand for scanning, then portability is improved, but scanning efficiency and ergonomics deteriorate because the device cannot be held parallel to the ground
Solution Approach 1:
The system is divided into two separate components: a mobile computing device and a handle adapter. The adapter can be attached to or detached from the device, allowing the scanning function to be segmented from the computing function. This enables the device to be held in optimal scanning orientation while maintaining portability when the adapter is detached.
Solution Approach 2:
The handle adapter serves as an intermediary component between the user's hand and the mobile computing device. It provides the ergonomic handle, trigger mechanism, and positioning structure that enables the device to be held parallel to the ground, while the device itself remains unchanged and portable.
2Ease of operation
If a handle adapter is added to the mobile computing device, then scanning ergonomics are improved, but device complexity increases
Solution Approach 1:
By segmenting the handle adapter as a separate attachable component rather than integrating it permanently into the device, the complexity is distributed. Users only deal with the additional complexity when the adapter is attached and needed for ergonomic scanning, while the device itself remains simple and portable.
Solution Approach 2:
The system transitions from a static configuration to a dynamic one where the handle adapter can be attached and detached as needed. This dynamic configuration allows the system to adapt to different operational requirements, providing ergonomic scanning when needed while maintaining simplicity when portability is the priority.
3Stability of the object's composition
If a secure attachment mechanism is implemented, then device stability is improved, but ease of attachment and detachment deteriorates
Solution Approach 1:
The biased latch mechanism automatically engages with the detent feature when the adapter is brought near the device, providing secure attachment without requiring manual intervention. The spring-loaded design ensures positive engagement while allowing simple one-handed attachment and detachment operations.
Solution Approach 2:
The complex multi-component mechanical fastening system is replaced with a simple biased latch and detent feature mechanism. This substitution maintains secure attachment through elastic force and geometric interlocking while enabling easy one-handed operation for attachment and detachment.
4Reliability
If a biased latch mechanism is used, then attachment security is improved, but mechanism complexity increases
Solution Approach 1:
A complex multi-component mechanical fastening system is replaced with a simple biased latch mechanism that uses elastic force from a spring and geometric interlocking with a detent feature. This substitution achieves reliable secure attachment through basic mechanical principles while minimizing the number of parts and overall mechanism complexity.

AI summary
An adapter is disclosed herein. The adapter comprises a base, at least one retention element, a biased latch, a handle, and a switch. The base has a first surface and a second surface opposite the first surface. The first base surface is configured to receive a first surface of a mobile computing device. The at least one retention element is positioned on a front end of the base and is configured to receive a first end of the mobile computing device. The biased latch is positioned on a rear end of the base and is adapted to attach a second end of the mobile computing device. The handle is positioned on the second base surface and the switch is positioned on the second base surface adjacent to the handle. The switch is mechanically linked to the biased latch, and the biased latch is configured to release the mobile computing device from the base when the switch is actuated.
