Portable Terminal Holder With Detachable Communication Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable-terminal holders and radio communication systems face inefficiencies due to limited cable lengths, requiring users to frequently move devices for charging and ID configuration, which decreases working efficiency and complicates device connections, especially in distant workplaces and systems without display devices.
Innovation Solution
A portable-terminal holder with a detachable communication module that allows wireless charging and data transmission up to 10 meters, and a radio communication system that simplifies ID configuration by using local IDs instead of absolute IDs, enabling users to manage device connections without displaying detected terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cable length connecting the holder and host computer is limited to 1m-3m, then the connection stability is maintained, but the user has to bring the scanner unit to the holder placed in a location distant from the workplace, which lowers working efficiency
Solution Approach 1:
The holder is divided into two separable parts: a base unit that can be placed at the workplace and a communication module that connects to the host computer via cable. This segmentation allows the base to be positioned independently near the user's workspace while the communication module remains connected to the computer, eliminating the need to move the entire holder or scanner unit to a distant location for charging.
Solution Approach 2:
The base acts as an intermediary device between the scanner unit and the host computer. It provides local charging capability at the workplace while maintaining communication with the host computer through the cable-connected communication module, thus mediating between the need for local convenience and remote computer connection.
2Reliability
If the absolute ID is described by a very long code (48-bit Bluetooth address), then the unique identification is achieved, but the code is hard for users to recognize and handle
Solution Approach 1:
The system creates a simplified copy or representation of the absolute ID through the local ID. Instead of requiring users to directly handle and remember the complex 48-bit Bluetooth address, the system uses a shortened local ID that serves as a convenient reference, while the full absolute ID is stored and used internally for unique identification and connection authentication.
3Device complexity
If the host computer is not provided with a display device, then the system simplicity is maintained, but the user cannot easily select the intended communication target from detected radio communication terminals
Solution Approach 1:
The base unit provides self-service functionality by displaying detected radio communication terminals and their local IDs locally, without requiring the host computer's display. This allows users to easily select communication targets at the workplace while the base handles the complexity of terminal detection and management independently.
Solution Approach 2:
The display function is moved from the host computer dimension to the base unit dimension. By placing the display capability at the local workplace station rather than relying on the remote computer display, the system enables terminal selection at the point of use without adding complexity to the computer itself.

AI summary
A portable-terminal holder for holding a portable terminal that has a rechargeable battery and a first radio communication device is constituted by a base and c communication module. The base has a portion on which the portable terminal is placed, and a charging device for charging the rechargeable battery of the portable terminal while said portable terminal is placed on the portion. The communication module has a second radio communication device communicating with the first radio communication device for wireless data transmission between the portable terminal and the communication module, and a cable communication device communicating with an external host computer for cable data transmission between the host computer and the communication module. The communication module is configured to be detachable from the base.
