Telescopic Support Locking Assembly for Fast Height Adjustment

Solution Overview

Problem

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

Innovation Solution

A telescopic support with a locking component that includes a housing, driving component, and a linkage mechanism, allowing for quick and reliable locking and unlocking of tube connections through a spring-activated mechanism, enabling easy height adjustment.

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 tube positions, but the adjustment process becomes complicated and time-consuming

Engineering Contradiction:

Improvetube position stabilityVSAvoidadjustment time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The locking device automatically locks the tube component when the telescopic support is extended or retracted. The locking member engages with the tube component without requiring manual intervention, allowing the system to lock itself during normal operation. This eliminates the need for separate manual locking actions while maintaining stable tube positions.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The locking member is pre-positioned and spring-loaded to engage with the tube component before any adjustment is needed. When the telescopic support reaches its extended or retracted position, the locking member automatically engages to secure the tube component, preparing the system for stable operation in advance.

Inventive Principle:

Principle #10Preliminary action

2Reliability

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

Engineering Contradiction:

Improvetube position stabilityVSAvoidadjustment effort

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The locking device automatically locks the tube component when the telescopic support is extended or retracted. The locking member engages with the tube component without requiring manual intervention, allowing the system to lock itself during normal operation. This eliminates the need for separate manual locking actions while maintaining stable tube positions.

Inventive Principle:

Principle #25Self-service

3Reliability

If locking device is manually tightened to lock tube positions, then the telescopic support can prevent longitudinal movement, but the adjustment process becomes complicated

Engineering Contradiction:

Improvelongitudinal movement preventionVSAvoidadjustment procedure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The locking device automatically locks the tube component when the telescopic support is extended or retracted. The locking member engages with the tube component without requiring manual intervention, allowing the system to lock itself during normal operation. This eliminates the need for separate manual locking actions while maintaining stable tube positions.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The locking member is designed to dynamically engage and disengage based on the position of the telescopic support. As the support extends or retracts, the locking member automatically transitions between locked and unlocked states, eliminating the need for static manual adjustment procedures.

Inventive Principle:

Principle #15Dynamics
