Telescopic Camera Support With Automatic Tube Locking

Solution Overview

Problem

Conventional telescopic supports for photographic equipment require manual and labor-intensive adjustment, which can be time-consuming and may miss crucial moments during photography.

Innovation Solution

A telescopic support with a locking component comprising a housing, driving component, first and second bases, and a linkage component that allows for quick and easy locking and unlocking of tube connections using a driving member and elastic elements to automate the height adjustment process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual locking device is used to lock adjacent tubes, then the telescopic support can maintain stable height, but the adjustment process becomes complicated and time-consuming

Engineering Contradiction:

Improveheight stabilityVSAvoidadjustment time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The locking device automatically locks the telescopic support tubes through the weight of the photographic equipment itself. When the tubes are extended to the desired height, the equipment's weight causes the locking member to engage with the tube, providing automatic locking without manual intervention. This eliminates the need for manual operation while maintaining reliable height stability.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the traditional manual mechanical locking system with an automatic mechanical system driven by gravitational force. The locking member is designed to be pushed outward by the equipment's weight, which automatically engages the locking mechanism. This substitution eliminates manual operation while maintaining the mechanical reliability of the locking function.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If manual locking device is used to lock adjacent tubes, then the telescopic support can maintain stable height, but the adjustment process becomes labor-intensive

Engineering Contradiction:

Improveheight stabilityVSAvoidadjustment ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The locking device automatically locks the telescopic support tubes through the weight of the photographic equipment itself. When the tubes are extended to the desired height, the equipment's weight causes the locking member to engage with the tube, providing automatic locking without manual intervention. This eliminates the need for manual operation while maintaining reliable height stability.

Inventive Principle:

Principle #25Self-service

3Device complexity

If traditional locking mechanism is used, then the structure can be simple, but the adjustment speed is slow and may miss crucial photographic moments

Engineering Contradiction:

Improvestructure simplicityVSAvoidadjustment speed

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The locking device automatically locks the telescopic support tubes through the weight of the photographic equipment itself. When the tubes are extended to the desired height, the equipment's weight causes the locking member to engage with the tube, providing automatic locking without manual intervention. This eliminates the need for manual operation while maintaining reliable height stability.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The locking member is pre-positioned within the tube structure, ready to engage immediately when the telescopic tubes reach the desired position. The automatic locking action occurs instantaneously upon reaching the target height, eliminating the delay between extension and locking that characterizes manual systems.

Inventive Principle:

Principle #10Preliminary action
