Wearable Scanner Display Forearm Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable electronic devices with display screens on the wrist struggle to provide clear and immediate visual recognition of code information due to limited screen size and stability issues when the scanner is positioned to face a subject, making it difficult to confirm read code information efficiently.
Innovation Solution
A wearable electronic device configuration that includes a scanner and display panel positioned on the forearm, with a flexible mounting body that allows for easy operation and visibility, featuring a long glove-like design with a two-layer structure, cylindrical portions for finger fixation, and belt-shaped portions for wrist and forearm support, ensuring the display panel is within the user's field of view without hindering arm motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display screen is arranged on the wrist close to the back of the hand, then the device can be worn like a watch, but it becomes difficult for the user to visually recognize the display screen when the scanner faces the subject
Solution Approach 1:
The mounting body allows the display panel to be positioned dynamically on the forearm rather than fixed on the wrist, enabling the display to remain visible while the scanner rotates to face different directions. This dynamic positioning resolves the conflict between wearable convenience and visual accessibility.
Solution Approach 2:
The display panel is relocated from the wrist (one dimension) to the forearm (another dimension along the arm), creating spatial separation between the display and scanner. This dimensional change allows both components to function optimally without interfering with each other's visibility or operation.
2Area of stationary object
If the display screen area is limited to watch dial size, then the device maintains compact wearability, but the amount of information that can be simultaneously displayed is small
Solution Approach 1:
By moving the display to the forearm, the patent gains additional spatial room, allowing the display area to expand beyond watch dial dimensions. This dimensional relocation enables larger screen real estate while maintaining wearable form factor.
3Stability of the object's composition
If the scanner is positioned on a band wound around the wrist, then the device can be worn securely, but stability decreases when the size is increased
Solution Approach 1:
The patent distributes components along the forearm dimension rather than concentrating them on the wrist circumference. This linear arrangement along the arm's length provides a larger base area for mounting, improving stability even as device size increases.
Solution Approach 2:
The mounting body is segmented into cylindrical portions for finger fixation and belt-shaped portions for wrist and forearm support. This segmentation allows the device to anchor at multiple points along the arm, distributing mechanical load and maintaining stability with larger component sizes.
4Productivity
If the scanner is positioned to face the subject, then reading function is enabled, but it becomes difficult to confirm read code information immediately on the display
Solution Approach 1:
By separating the scanner (on the hand) from the display (on the forearm), the patent creates independent positioning freedom for each component. The scanner can face the subject for efficient reading while the display positions information within the user's field of view, eliminating the time delay for information confirmation.
