Battery-Powered Dolly for Cable-Free Stage Equipment Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dollies for transporting lighting equipment on stages face challenges such as space constraints, trip hazards from power cables, and the need to disconnect and reconnect electrical equipment during movement, which is time-consuming and disrupts power supply.
Innovation Solution
A dolly with a built-in battery that powers electrical equipment, featuring secure attachment points and wheels that allow simultaneous movement and power supply without cables, along with wireless DMX control for easy maneuverability and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power cables are run between power sockets and electrical equipment, then electrical equipment can be powered, but trip hazards are created and space is restricted
Solution Approach 1:
The patent extracts the power source (battery) from its traditional fixed location (power socket) and integrates it directly into the mobile dolly platform. This eliminates the need for power cables connecting external power sources to electrical equipment, thereby removing trip hazards while maintaining reliable power supply to equipment on the dolly.
2Adaptability or versatility
If portable batteries are moved to locations near electrical equipment, then power can be provided, but more space is required and trip hazards remain
Solution Approach 1:
The patent merges the battery with the dolly platform into a single integrated unit. The battery is mounted on the platform and moves together with the electrical equipment, eliminating the need for separate battery placement and reducing the total space required compared to having both equipment and battery as separate movable components.
3Ease of operation
If electrical equipment and power sources are moved separately, then flexibility is maintained, but time is lost and power supply may be interrupted
Solution Approach 1:
By integrating the battery into the dolly platform, the system enables simultaneous movement of both power source and electrical equipment as a single unit. This eliminates the time-consuming process of disconnecting, moving, and reconnecting equipment separately, while maintaining the flexibility to relocate the entire system as needed.
4Area of stationary object
If electrical equipment is placed on the dolly platform, then space is saved, but equipment may fall off during movement
Solution Approach 1:
The patent incorporates attachment points (such as ropes, straps, or mechanical fasteners) on the dolly platform that can secure electrical equipment before movement begins. This preliminary securing action prevents equipment from falling off during transport while maintaining space efficiency by keeping equipment on the platform rather than requiring separate storage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The dolly provides safe, space-efficient, and uninterrupted power to electrical equipment, enabling simultaneous movement and secure attachment, reducing trip hazards and improving portability and safety on stages.
