Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Retail displays for hand-held electronics face challenges in providing both power and security functionalities without the need for complex multi-conductor retractors, which are prone to wear and tear and voltage fluctuations, and struggle to adapt to devices with different power requirements.
Innovation Solution
The implementation of a wireless security system that uses a mechanical reel with a steel cable for physical security, combined with a puck electronics board that communicates security breaches wirelessly and provides power to hand-held devices through a single-source power signal, eliminating the need for continuous wire connections and allowing for easy swapping of devices with different power requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multi-conductor retractors are used to provide both power and security signals, then both power supply and security functionality are achieved, but the system becomes prone to wear and tear, voltage fluctuations, and cable tangling
Solution Approach 1:
The patent divides the previously integrated multi-conductor retractor system into separate components: a mechanical retractor providing only physical security tethering, and separate power supply mechanisms. This segmentation eliminates the wear and voltage fluctuation problems of the multi-conductor design while maintaining both security and power functionality.
Solution Approach 2:
The patent extracts the electrical conductor wires from the mechanical retractor cable, leaving only the mechanical tethering function. The electrical power and security signal functions are then provided through separate, dedicated pathways, removing the source of wear and voltage instability from the retractor system.
2Use of energy by moving object
If separate power cables are provided for each device position, then power supply to individual devices is ensured, but cable management becomes complex and swapping devices requires changing multiple cables
Solution Approach 1:
The patent combines multiple electrical functions (power supply and security signaling) into a single communication protocol transmitted over the existing mechanical retractor cable infrastructure. This merging eliminates the need for separate power cables at each device position, simplifying cable management while maintaining full functionality.
Solution Approach 2:
The patent implements a universal communication protocol that can transmit both power control and security signaling functions through the existing cable infrastructure. This multi-functional approach allows the same cable system to serve multiple purposes, reducing overall system complexity.
3Strength
If a mechanical retractor with steel cable is used for physical security, then tethering strength is improved, but the ability to transmit power and security signals is lost
Solution Approach 1:
The patent introduces an intermediary communication system that uses the mechanical retractor cable as a physical tether while employing separate wireless or alternative signaling pathways for transmitting power and security information. This intermediary approach allows the steel cable to fulfill its mechanical strength function without compromising signal transmission capabilities.
