Modular Barcode Scanner Hand Wearable for Adjustable Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hand wearables for barcode scanners are limited by size customization, hygiene issues, ergonomic inefficiencies, and premature retirement of integrated trigger devices, leading to increased costs and reduced usability across a diverse group of operators.
Innovation Solution
A hand wearable support for a barcode scanner featuring a modular design with adjustable straps and detachable trigger and scanner components, allowing for customizable fit and independent maintenance of parts, enhancing ergonomics and longevity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a glove covers both the back of the hand and the palm of the hand with multiple layers of material, then the hand wearable provides comprehensive coverage and support, but heat and moisture generated by the hand are built up and contained inside the wearable, causing hygiene problems
Solution Approach 1:
The hand wearable is divided into two separate components: a glove portion covering the back of the hand and a wristband portion wrapping around the wrist and palm. This segmentation allows the glove portion to provide support while the wristband portion manages moisture and heat, preventing buildup inside the wearable.
Solution Approach 2:
The palm coverage is extracted from the glove portion and relocated to the wristband portion. The wristband wraps around the wrist and extends toward the palm, providing necessary coverage without enclosing the hand completely, thus allowing heat and moisture to escape.
2Ease of operation
If the hand wearable is sized for a custom fit to an operator, then the glove provides comfortable and secure fit, but this limits the use of the glove to the operator or others having a similar hand configuration, requiring each operator to have their own glove which increases cost
Solution Approach 1:
The wristband portion includes an adjustable strap with a buckle that can be tightened or loosened to accommodate different hand sizes. This dynamic adjustment capability allows a single wristband to fit multiple operators with varying hand configurations, eliminating the need for custom-sized gloves for each operator.
3Reliability
If the trigger device and associated components are integrated into the hand wearable, then the trigger device is securely positioned, but any failure of the hand wearable that requires retirement also results in retiring of the trigger device even if it is still operable, leading to increased total cost
Solution Approach 1:
The trigger device is separated from the hand wearable and mounted on a bar code scanner attachment that can be independently removed and replaced. This segmentation allows the trigger device to remain securely positioned during use while enabling independent replacement of the bar code scanner attachment when it fails, without retiring the still-operable trigger device.
4Device complexity
If conventional gloves are limited in their adjustability, then the glove structure remains simple, but this further limits the glove to a particular size and form factor of a hand
Solution Approach 1:
The wristband portion incorporates an adjustable strap with a buckle mechanism that allows dynamic adjustment of the fit. This simple addition enables the wristband to accommodate various hand sizes and shapes without significantly complicating the overall glove structure.

AI summary
Hand wearable support for a bar code scanner comprises back and front sides. The front side includes a V-member, first and second harness straps attached thereto extending away from each other at an angle, and means along the V-member for releasably attaching the front to the back side of the support which further comprises a back of the hand portion, a thumb portion, a trigger attachment portion, and first and second strap attachment portions each including a buckle. The first and second harness straps of the front side include a tongue portion for threading through the first and second buckle and folding back to releasably attach to itself. Releasable attachment of a trigger device, bar code scanner attachment, and bar code scanner to trigger attachment portion, bar code scanner attachment portion, and bar code scanner attachment portion, respectively, forms a bar code scanner assembly in the form factor of a support wearable by a user to perform scanning operations.
