Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Contemporary tripods have adjustment limitations that restrict the angular positioning of their legs relative to the vertical, affecting the stability and positioning of photographic devices, especially when the legs are at 90 degrees to the vertical.
Innovation Solution
A tripod system with continuously adjustable leg-to-vertical angle adjustment, allowing precise height-above-base vertical positioning through a fixed hub and movable tubular rod system, combined with telescopic leg extensions for optimal stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If contemporary tripods use fixed angular positions for legs, then the structure is simple and easy to manufacture, but the positioning flexibility and stability are limited
Solution Approach 1:
The tripod leg support mechanism transitions from fixed angular positions to continuously adjustable angular positions. The leg can rotate freely around the vertical axis and be locked at any desired angle, providing dynamic adaptability while maintaining structural simplicity through the use of a locking mechanism at the hub.
Solution Approach 2:
The leg-to-vertical angle parameter is changed from discrete fixed values to continuous adjustable values ranging from 0 to 90 degrees. This allows optimization of stability and positioning for different photographic devices and shooting scenarios while using a straightforward locking mechanism to maintain the desired parameter.
2Reliability
If the leg angle is fixed at one position, then the device complexity is reduced, but the ability to achieve optimal stability at 90 degrees is lost
Solution Approach 1:
The tripod provides dynamic adjustment capability allowing the leg angle to be changed from fixed positions to continuous positions up to 90 degrees. This enables optimal stability configurations for different devices and shooting conditions while using a simple locking mechanism to maintain the chosen configuration.
Solution Approach 2:
The leg angle parameter can be continuously adjusted and locked at any value between 0 and 90 degrees, allowing optimization of tripod stability for different photographic devices and shooting scenarios without requiring a complex adjustment system.
3Measurement precision
If the tripod legs are limited to one angular position, then the manufacturing is simpler, but the positioning precision for high-resolution images is affected
Solution Approach 1:
The tripod leg support mechanism allows continuous angular adjustment and locking at any desired position, enabling precise positioning of the photographic device for high-resolution imaging while maintaining ease of manufacture through a straightforward locking mechanism at the hub.
Solution Approach 2:
The leg angle parameter is made continuously adjustable from 0 to 90 degrees with locking capability, allowing precise positioning of the photographic device for optimal image quality while using a simple manufacturing approach with a locking mechanism.

AI summary
The purpose of the photographic tripod is to prevent movement of the photographic device during the capture of an image. In addition, the photographic tripod should enable the user to precisely position the camera relative to the floor and the object that is being photographed. Tripod legs, when unfolded, create an effective circular base. However because of the way they are constructed tripods typically allow the legs to unfold to a fixed angle essentially 45 degrees to the vertical. As the camera height position is increased, this makes the base that's created less stable. The invention makes use of novel structures to enable continuous angular leg adjustment, between, essentially, 0 and 90 degrees. As such, it allows a wider, effective, circular base and more secure support.
