Photo Booth Rotating Arm Structure for Stable Counterweight-Free Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing photo booth support structures require counterweights for balance, leading to increased material costs and structural redundancy, and manual operation results in uneven rotation speed and jittering of shooting images.
Innovation Solution
A support driving structure comprising a main shaft, a gear or belt wheel driven by an electric motor, and a rotating arm connected to the driven wheel, which rotates uniformly without a counterweight, ensuring stable and balanced operation of the shooting device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If counterweight blocks are added to balance the horizontal rod, then the horizontal rod can be balanced, but the structure becomes more complex and material costs increase
Solution Approach 1:
The patent removes the counterweight block from the system entirely. Instead of adding balancing components, the design uses the weight distribution of existing components (horizontal rod, connecting rod, shooting device) to achieve natural balance, thereby eliminating structural redundancy while maintaining balance stability.
Solution Approach 2:
The patent applies counterbalance through the geometric arrangement and weight distribution of existing components rather than additional counterweight blocks. The connecting rod and horizontal rod are positioned to create inherent balance, achieving the counterweight effect without the harmful addition of extra components.
2Ease of operation
If manual pushing is used to rotate the horizontal rod, then the shooting device can be rotated, but the rotation speed becomes uneven causing image jittering
Solution Approach 1:
The patent replaces the manual mechanical pushing system with an electric motor-driven system. The motor provides controlled, uniform rotational motion through the connecting rod and horizontal rod, eliminating the speed variability and image jittering caused by manual operation while maintaining ease of operation through automated control.
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 solution provides reliable stability and balanced rotation of the shooting device at uniform or variable speeds, eliminating the need for counterweights and reducing material costs while preventing image jittering.
Implementation Method 1
The rotating structure is an electric motor configured to transmit power to the driven wheel, and the driven wheel receives the power to drive the rotating arm to rotate at a uniform speed or a fast, slow, or variable speed
Implementation Method 2
The driven wheel is sleeved on the supporting main shaft and is rotatably connected to the supporting main shaft

AI summary
A support driving structure of a photo booth includes: a supporting main shaft, a driven wheel, and a rotating arm. The driven wheel is sleeved on the supporting main shaft and is rotatably connected to the supporting main shaft. The rotating arm is connected to an end surface of the driven wheel. The driven wheel is rotatably connected to the supporting main shaft through a bearing. The rotating arm is connected to the end surface of the driven wheel through screws. The rotating arm is of a frame structure. The rotating arm includes long rods, short rods, and connecting sheets. Two ends of each of the short rods and two ends of each of the connecting sheets are both connected to the two long rods. Connecting positions are defined on the connecting sheets. Connecting portions corresponding to the connecting positions are disposed on the driven wheel.
