Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Clamping assemblies in camera stabilizers fail to supply power to function expansion modules, leading to increased weight and reduced grip experience due to separate battery modules, and increased load on support arms, resulting in a shorter service life.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate battery modules are arranged in function expansion modules to enable independent operation, then the function expansion modules can operate independently, but the overall weight of the function expansion modules increases greatly, leading to poor grip experience
Solution Approach 1:
The patent merges the power supply function from the clamping assembly to the function expansion module by integrating power supply contacts on the clamping blocks and power receiving pins on the function expansion modules. This allows the function expansion modules to receive power from the main stabilizer body, eliminating the need for separate battery modules and significantly reducing overall weight while maintaining independent operation capability.
Solution Approach 2:
The clamping assembly is designed with dual functionality: it provides both mechanical clamping support and electrical power supply. The guide pillars serve both as mechanical guides for the clamping blocks and as conductive paths for power transmission, enabling a single component to fulfill multiple functions and reduce the need for additional separate battery modules.
2Power
If separate battery modules are arranged in function expansion modules, then power supply is ensured, but the load borne by the support arm increases, leading to a shorter service life of the camera stabilizer
Solution Approach 1:
The patent combines the power supply function into the main clamping assembly structure, where the guide pillars serve as both mechanical guides and electrical conductors. This integration allows power to be transmitted to function expansion modules without adding separate battery modules, thereby reducing the load on the support arm and extending the service life of the camera stabilizer.
Solution Approach 2:
The guide pillars act as intermediary elements that transmit both mechanical motion and electrical power from the clamping assembly to the function expansion modules. This dual role of the guide pillars as mechanical and electrical intermediaries enables power supply without increasing the load on the support arm, thus preserving the service life of the stabilizer.
3Power
If guide pillars are made conductive to supply power, then power transmission is achieved, but the structural complexity of the clamping assembly increases
Solution Approach 1:
The guide pillars are designed to perform multiple functions simultaneously: they guide the movement of clamping blocks mechanically and transmit electrical power to function expansion modules. By making the existing guide pillars conductive rather than adding separate power transmission components, the patent achieves power supply capability while minimizing increases in structural complexity.
Solution Approach 2:
The patent merges the electrical conduction function into the existing mechanical guide pillar structure. Instead of adding separate power transmission mechanisms, the guide pillars are made conductive to serve both mechanical guidance and electrical power transmission purposes, thereby achieving power supply without significantly increasing device complexity.

AI summary
Disclosed are a clamping assembly and a handheld auxiliary photographic device using the clamping assembly. The clamping assembly comprises a main shell and clamping blocks, wherein a main control board and at least one group of guide pillars electrically connected to the main control board are arranged in the main shell, and the guide pillars are able to retract into and stretch out of one end surface of the main shell; and at least two clamping blocks are respectively arranged at two ends of the main shell to form a clamping area and are correspondingly connected to the guide pillars stretching out of the main shell at the same end. The guide pillars, as conducting structures, work together with power supply contacts formed on surfaces of the clamping blocks to supply power to external function expansion modules to drive the function expansion modules.
