Reconfigurable Sled Mirror for Indicia Reading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile device accessories for indicia reading, such as scanning sleds, are costly and bulky, and fixed optical redirection adapters do not interact with the mobile device, limiting camera usage and requiring manual configuration for indicia reading.
Innovation Solution
A reconfigurable sled that redirects the mobile device's camera imaging direction using a mirror with visible markings, allowing the mobile device to perform indicia reading by detecting these markings in acquired images and adjusting camera settings, and optionally includes a motion control subsystem and aimer subsystem for enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed optical redirection adapter is used to redirect camera imaging, then indicia reading capability is enabled, but the mobile device's normal camera usage is limited and manual configuration is required
Solution Approach 1:
The patent employs a movable mirror that can be dynamically positioned between a retracted state (normal camera operation) and an extended state (indicia reading mode). This dynamic mechanism allows the system to adapt between different functional states, enabling both normal photography and barcode scanning without permanent optical path modification.
Solution Approach 2:
The sled assembly serves multiple functions: it acts as a protective case for the mobile device, houses an optical redirection system for indicia reading, and includes a movable mirror mechanism. This multi-functional design eliminates the need for separate dedicated barcode scanners while maintaining normal camera operation.
2Adaptability or versatility
If a scanning sled is used for indicia reading, then indicia reading functionality is achieved, but cost and device bulkiness increase
Solution Approach 1:
The patent combines the protective case, optical redirection system, mirror mechanism, and indicia reading functionality into a single integrated sled assembly. This merging of functions into one compact unit reduces overall device bulkiness compared to separate components while maintaining full indicia reading capability.
Solution Approach 2:
The sled serves as both a protective case and a functional indicia reading device, eliminating the need for separate barcode scanner hardware. This multi-functional approach reduces device bulkiness and cost while maintaining versatility.
3Adaptability or versatility
If a fixed adapter is used for optical redirection, then indicia reading is enabled, but the system cannot communicate with or configure the mobile device
Solution Approach 1:
The system includes a sensor that detects the presence and position of the movable mirror, providing feedback to the mobile device. This feedback mechanism enables automatic configuration of camera parameters (such as focus and exposure) when the mirror is extended for indicia reading, eliminating manual setup requirements.
Solution Approach 2:
The movable mirror mechanism includes visible markings that automatically appear in the camera viewfinder when extended. The system self-configures by detecting these markings and automatically adjusting camera settings, eliminating the need for manual intervention or complex communication protocols.

AI summary
A reconfigurable sled for a mobile device with camera is provided. The reconfigurable sled may be moved into different configurations in order to facilitate either normal or specialized use. For example, in a first configuration, the mobile device's camera is unobstructed and imaging may proceed normally. In a second configuration, on the other hand, the camera's imaging direction may be repositioned by a reflective element in the camera's optical path. The reflective element provides feedback to the mobile device via visible markings that may be imaged by the camera and detected by the mobile device. If the mobile device determines that the mirror is in the optical path, then the mobile device may respond to accommodate the mirror and enable a function, like reading an indicium.
