Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile hydraulic stage systems lack a convenient and efficient method for transforming between deployed and transport positions, requiring cumbersome wired or wireless control packs that restrict user mobility and increase setup/takedown time.
Innovation Solution
A wireless control system using a mobile computing device, such as a smartphone or tablet, that interfaces with a receiver unit to control a hydraulic system, allowing the stage to be transformed between positions without physical constraints, utilizing Bluetooth or Wi-Fi technology for communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wired or wireless control packs are used to control the hydraulic system, then the stage can be transformed between deployed and transport positions, but user mobility is restricted and setup/takedown time increases
Solution Approach 1:
The patent replaces the mechanical wired control pack system with a wireless communication system using Bluetooth or Wi-Fi technology. The mobile computing device communicates wirelessly with the receiver unit on the stage, eliminating physical wires and control packs, thereby enhancing user mobility while maintaining control functionality.
Solution Approach 2:
The patent introduces a receiver unit as an intermediary component mounted on the stage. This receiver unit receives wireless signals from the mobile computing device and relays commands to the hydraulic system, enabling wireless control while maintaining system reliability and control precision.
2Reliability
If wired control packs are used, then control functionality is maintained, but the system becomes more complex and cumbersome
Solution Approach 1:
The patent replaces the complex mechanical wired control pack system with a wireless communication system. The mobile computing device uses Bluetooth or Wi-Fi to communicate with the receiver unit, eliminating the need for physical wires, connectors, and control packs, thereby reducing system complexity while maintaining control functionality.
Solution Approach 2:
The patent utilizes the mobile computing device's existing wireless communication capabilities (Bluetooth, Wi-Fi) to control the hydraulic system. This multi-functional approach allows the device to serve both as a general-purpose computing device and as a control interface, reducing the need for dedicated control equipment.
3Ease of operation
If traditional control methods are used, then the hydraulic system can be operated, but operators must be physically close to the stage
Solution Approach 1:
The patent replaces physical proximity-based control with wireless communication. The mobile computing device can send commands to the receiver unit on the stage from a distance using Bluetooth or Wi-Fi signals, allowing operators to control the hydraulic system without being physically close to the stage, thereby improving operational flexibility and reducing setup time.

AI summary
A deployable mobile stage system including a remote mobile computing device which acts as a controller. The mobile computing device can be any basic personal computing device such as a smart phone, tablet computer, laptop, or proprietary control unit. The mobile computing device interfaces wirelessly with a receiver unit located on the mobile stage. The receiver unit relays commands to a hydraulic system which then commands various valves to open and/or close, thereby transforming the mobile stage from a first, deployed position to a second, transport position or back.
