Platform Lift RF Configuration via Wireless Signal Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current platform lift manufacturing processes are complex and inefficient due to the need for country-specific components to comply with varying RF frequency and ERP standards, leading to production challenges and potential waste, as lifts cannot be easily adapted for different markets.
Innovation Solution
A method of configuring platform lifts using RF communication devices that allow for uploading country-specific settings during production or installation, enabling the platform lift to operate within specific frequency ranges, thereby simplifying production and adaptability across different regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If platform lifts are produced with customized hardware and software for each country, then compliance with local RF standards is achieved, but manufacturing complexity increases and production efficiency decreases
Solution Approach 1:
The patent segments the configuration process from the hardware manufacturing process. Country-specific RF parameters (frequency, ERP) are separated as independent software configurations that can be applied after production, rather than being hard-coded into custom hardware for each country. This allows standardization of manufacturing while maintaining compliance through software segmentation.
Solution Approach 2:
The patent implements preliminary configuration by pre-programming multiple country-specific RF parameter sets into the platform lift's memory during manufacturing. This preliminary action stores all possible country configurations in advance, allowing rapid switching between countries without requiring custom hardware production for each market, thus reducing manufacturing complexity while ensuring compliance.
2Reliability
If country-specific components are selected and inserted during production, then local regulatory requirements are met, but production time increases and waste potential increases
Solution Approach 1:
The patent makes the platform lift universal by equipping it with a single standardized hardware platform that can operate in multiple countries. The RF communication device is designed to support multiple frequency ranges and ERP levels through software configuration rather than requiring country-specific hardware variants. This multi-functionality allows one production line to serve all markets, dramatically improving productivity while maintaining regulatory compliance through configurable parameters.
Solution Approach 2:
The patent resolves the contradiction by changing the approach from hardware customization to parameter configuration. Instead of selecting and inserting different physical components for each country, the system changes RF operating parameters (frequency, power) through software. This parameter-based approach maintains regulatory compliance while enabling standardized, efficient production without country-specific component assembly, thus improving productivity.
3Ease of operation
If platform lifts are configured with specific country settings during production, then they are ready for immediate use, but adaptability to other markets is reduced
Solution Approach 1:
The patent introduces dynamics by making the RF configuration changeable and adaptable rather than fixed. The platform lift is equipped with a programmable RF communication device that can dynamically switch between different country-specific parameter sets stored in memory. This dynamic capability allows the device to be configured for immediate use in one country while retaining the ability to be reconfigured for other markets, thus maintaining both ease of operation and adaptability.

AI summary
A method of configuring a platform lift, having a drive unit with a communication device and a remote device in communication with the communication device so the remote device provides a user input to the control unit, is disclosed. The method includes uploading a selected country specific setting into the communication device, emitting an introductory signal from the communication device to the remote device, emitting an acknowledgement signal from the remote device back to the communication device, emitting from the communication device a first signal containing information corresponding to the uploaded country specific setting, receiving the emitted first signal at the remote device, configuring the remote device by recognizing the country specific setting in the first signal, selecting at the remote device the same country specific setting, and emitting a confirmation signal from the remote device back to the communication device which conforms to the selected country specific setting.
