Shooting Stand Counterweight Linkage for Telescopic Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shooting stands experience poor stability due to uneven load distribution when the telescopic part is extended, leading to shaking and reduced shooting effectiveness.
Innovation Solution
A shooting stand with a balancing weight system, featuring a telescopic member, guide wheel, rope, and balancing rod, where the rope is connected to both the telescopic part and the balancing rod, allowing the balancing rod to pivot and swing to balance the load when the telescopic part is extended or retracted, ensuring uniform load distribution on both sides of the standing frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the telescopic part is extended to adjust the shooting apparatus position, then the shooting angle and position flexibility is improved, but the load distribution on the standing frame becomes uneven causing shaking and reduced stability
Solution Approach 1:
The patent introduces a balancing rod with a counterweight that pivots on the standing frame. When the telescopic part extends and creates uneven load distribution, the counterweight automatically adjusts its position to generate a balancing moment that offsets the unbalanced load, thereby maintaining standing frame stability while allowing full telescopic range for shooting flexibility.
2Length of moving object
If the telescopic part is extended to maximum position, then the shooting distance and composition variety is improved, but the load difference on both sides of the standing frame becomes great causing shaking
Solution Approach 1:
The counterweight system is specifically designed to compensate for the maximum extension position where the load difference is greatest. The counterweight pivots to its extreme position, generating maximum balancing moment to counteract the large unbalanced load, thereby eliminating shaking even at maximum telescopic extension.
Solution Approach 2:
The balancing rod is designed as a dynamic component that automatically adjusts its pivot position in real-time as the telescopic part moves. This dynamic adjustment ensures continuous load balancing throughout the entire range of motion, preventing shaking at any extension position rather than only at fixed points.
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 balancing weight system stabilizes the standing frame by maintaining uniform load distribution, enhancing the shooting effect by reducing shaking and improving stability.
Implementation Method 1
when the telescopic part is retracted relative to the fixed part, the rope is loosened to cause the balancing rod to pivot or swing away from the cantilever arm under an action of a dead weight thereof

AI summary
A shooting stand with a balancing weight includes a standing frame, a top base, an installing support, a telescopic member, a guide wheel, a rope and a balancing rod. The balancing rod is hinged with the top base, and the balancing rod is extended along a direction away from the top base, the rope goes around the guide wheel, one end of the rope is connected to the telescopic part or the installing support, and the other end is connected to the balancing rod away from the top base. When the telescopic part is extended, the rope is pulled to cause the balancing rod to pivot to approach the cantilever arm; when the telescopic part is retracted, the rope is loosened to cause the balancing rod to pivot away from the cantilever arm, and the rope is pulled to move again. The stability and reliability are improved.
