Back-of-Hand Data Capture Mount with Forearm-Aligned Optical Axis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing accessories for attaching data capture devices to an operator's hand are cumbersome, cause discomfort, and often misalign the device's optical axis, making it difficult to use intuitively.
Innovation Solution
A hand mount with a body that rests on the back of the hand, a mounting plate with a latch assembly, a proximal wing for the wrist, a distal wing for the index finger, and a trigger on the distal wing, allowing toolless attachment and intuitive alignment of the device's optical axis parallel to the forearm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing accessories are used to attach data capture devices to the hand, then the device can be mounted, but the accessories are cumbersome and cause discomfort
Solution Approach 1:
The mounting accessory is divided into multiple segments: a wrist strap component, a finger loop component, and a device holder component. This segmentation allows each part to be optimized independently - the wrist strap provides secure anchoring, the finger loop enables easy attachment/detachment, and the holder positions the device correctly, collectively solving both security and comfort requirements
Solution Approach 2:
The mounting system transitions from a single-plane attachment to a three-dimensional configuration spanning multiple body parts (wrist, fingers, hand back). By distributing attachment points across different spatial dimensions and body locations, the system achieves secure device mounting while avoiding concentration of pressure or bulk in one area, thereby improving operator comfort
2Reliability
If existing accessories are used to attach data capture devices, then the device can be mounted, but they are cumbersome to apply and operate
Solution Approach 1:
The finger loop component is pre-configured with an open configuration that allows the finger to be inserted first, followed by automatic engagement of the loop. This preliminary positioning action simplifies the overall attachment process, reducing the time and complexity of securing the device to the hand
Solution Approach 2:
The finger loop incorporates flexible, dynamic material that can deform during attachment and then lock into a secure configuration. This dynamic behavior allows for quick, toolless attachment while maintaining reliable security, eliminating the need for complex fastening mechanisms that would increase attachment time
3Ease of operation
If the device is mounted on the hand, then it is accessible, but the optical axis is misaligned and difficult to use intuitively
Solution Approach 1:
The device holder incorporates specific geometric features and positioning elements that locally adjust the device orientation. These localized structural qualities ensure the optical axis is precisely aligned parallel to the forearm while the rest of the mounting system maintains flexibility for comfortable hand positioning
Solution Approach 2:
The mounting structure uses asymmetric positioning of the device holder relative to the hand anatomy. This asymmetric configuration naturally orients the device's optical axis parallel to the forearm direction, improving intuitive aiming and alignment precision without requiring additional adjustment mechanisms

AI summary
A hand mount for a data capture device having an optical axis includes: a body configured to rest on a back of a hand of an operator; a mounting plate affixed to the body, the mounting plate defining a longitudinal axis; a latch assembly coupled to the mounting plate, the latch assembly configured to releasably secure the data capture device with the optical axis parallel with the longitudinal axis of the mounting plate; a proximal wing extending from a proximal end of the body, the proximal wing defining a proximal fastener configured to engage with a wrist of an operator; a distal wing extending from a distal end of the body at a nonparallel angle to the longitudinal axis, the distal wing configured to engage with a finger of the operator; and a trigger disposed on the distal wing.
