Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera stabilizers face challenges in fine-tuning tilt angles, securing cameras during attachment and detachment, and accommodating monitors on various post diameters, with existing solutions being cumbersome or requiring multiple parts.
Innovation Solution
A camera stabilizer system incorporating a tilt head with Vernier drive for precise angle adjustment, a payload plate clamping mechanism with automatic safety locking, and a monitor mount with interchangeable inserts for secure attachment to different post diameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional tilt heads are used, then the head can be locked in position, but fine adjustment of the tilt angle becomes difficult and the head requires a lot of force to release
Solution Approach 1:
The tilt adjustment mechanism is segmented into two independent functions: a Vernier drive system for fine angular adjustments and a separate release mechanism for easy head detachment. The Vernier scale divides the adjustment into precise incremental steps, while the release mechanism independently handles the locking function, allowing fine adjustment without compromising release ease.
Solution Approach 2:
A Vernier scale acts as an intermediary between the coarse adjustment mechanism and the final tilt angle positioning. This intermediary provides precise incremental adjustments through a series of marked positions, enabling fine control of the tilt angle without requiring direct manual manipulation of the entire adjustment range at once.
2Reliability
If conventional dovetail and clamp mechanisms are used, then the camera can be secured to the support structure, but the camera is free to fall out during attachment and detachment, requiring separate safety actions
Solution Approach 1:
The safety mechanism is merged with the clamping lever into a single integrated system. The lever and cam mechanism simultaneously perform both the clamping function and the safety locking function, eliminating the need for separate safety actions. As the operator manipulates the lever to attach or detach the camera, the safety mechanism is automatically engaged or disengaged as part of the same continuous motion.
Solution Approach 2:
The safety mechanism operates automatically through the lever's motion path, requiring no separate operator action. The cam profile is designed so that the lever's natural movement during camera attachment or detachment automatically initiates the safety locking or release, making the system self-servicing and eliminating additional manual steps.
3Adaptability or versatility
If conventional monitor mounts are used, then the monitor can be attached to the central post, but the mount cannot securely fix monitors to posts of different diameters without numerous additional parts
Solution Approach 1:
The monitor mount employs a universal clamping mechanism with adjustable features that can accommodate multiple post diameters using the same basic structure. The mount includes adjustable arms or a resizable clamping interface that can be configured for different post sizes, eliminating the need for multiple specialized mounts for different diameter posts.
Solution Approach 2:
The monitor mount incorporates dynamic, adjustable elements rather than fixed rigid structures. The clamping mechanism can be resized or reconfigured to match different post diameters, providing adaptability through movement and adjustment capability while maintaining a simple overall construction without requiring numerous additional parts for different sizes.

AI summary
The invention includes a payload stage with tilt head, a monitor mount and a payload plate clamping mechanism, individually, and incorporated into a camera stabilizer. The tilt head provides a curved and a straight slot each having a pivot pin disposed therein. The pivot pins are at a fixed distance from one another and thus the stage tilts as the pivot progresses with respect to the straight slot. The monitor mount provides inserts to accommodate central posts of different sizes, each designed to be axially registered to the posts and the monitor mount.
