Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cabled information code reading devices face challenges in cost reduction due to complex production management and potential damage from frequent connections, while wireless scanners are vulnerable to theft and require battery management, making them difficult to secure.
Innovation Solution
An information code reading device that uses external power supplied through a cable for operation, wirelessly transmits reading results, and employs a power storage circuit for notifications, preventing unauthorized removal and reducing wear on connectors by detecting power shut-offs and performing notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless scanner is used, then ease of operation is improved, but reliability deteriorates due to theft vulnerability
Solution Approach 1:
The patent introduces a cable as an intermediary component between the scanner and external devices. The cable serves as a physical constraint that prevents unauthorized removal of the scanner while still allowing wireless communication functionality. This intermediary element resolves the contradiction by providing both security (through physical connection) and operational flexibility (through wireless transmission).
Solution Approach 2:
The patent segments the functionality into two independent parts: wireless communication capability and power/data transmission through cable. The scanner can wirelessly transmit data to external devices while being physically constrained by the cable connection. This segmentation allows the device to maintain ease of operation for data transmission while improving reliability through physical security.
2Reliability
If cabled scanner is used, then reliability is improved, but ease of operation deteriorates due to frequent connections
Solution Approach 1:
The cable acts as an intermediary that provides reliable physical connection while enabling wireless data transmission. This allows the scanner to maintain reliability through continuous power and data connection while reducing the frequency of physical connections needed for data transfer.
Solution Approach 2:
The patent replaces the mechanical data transmission method (physical cable connection for both power and data) with a wireless communication system for data transfer. The cable continues to provide power and maintain physical connection for reliability, while wireless communication eliminates the need for frequent mechanical connections for data transfer.
3Adaptability or versatility
If cable connector is used frequently, then adaptability is improved, but loss of substance worsens due to wear and tear
Solution Approach 1:
The cable serves as a permanent intermediary connection that provides adaptability for different external devices while minimizing wear on connectors. By maintaining a continuous physical connection for power and data, the system reduces the frequency of connector engagements and disengagements, thereby reducing wear and tear.
Solution Approach 2:
The patent substitutes wireless communication for mechanical data transfer connections. This replacement significantly reduces the frequency of cable connector engagements, thereby minimizing wear and tear on the connectors while maintaining adaptability through wireless data transmission capabilities.
