Solution Overview

Problem

Existing stick tree guides are limited in construction height and require laborious repositioning, making it difficult to adjust their height safely and efficiently during structure erection.

Innovation Solution

A stick tree guide with a frame structure and receiving area that encloses the stick tree, allowing for linear movement along its longitudinal direction, featuring sliding elements with angled end sections to prevent unintended hooking and fastening elements for secure attachment, enabling easy height adjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of stationary object

If conventional pole supports are used, then they can be used up to a certain structural height, but repositioning is required which involves labor-intensive steps

Engineering Contradiction:
Improvestructural heightVSAvoidrepositioning operation
Core Design Contradiction:
Length of stationary objectVSEase of operation

Solution Approach 1:

The pole guide is designed to move dynamically along the pole through a receiving area that allows linear movement in the guide direction. The sliding elements enable the guide to transition smoothly between positions without labor-intensive repositioning operations, while maintaining stable contact with the pole throughout the movement range.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The pole guide is divided into modular components including a frame structure, sliding elements, and receiving area that can be independently positioned. This segmentation allows the guide to be repositioned along the pole by adjusting individual components rather than moving the entire structure, reducing labor intensity.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If the receiving area encloses the pole completely, then stabilization is improved, but the complexity of the frame structure increases

Engineering Contradiction:
Improvepole stabilizationVSAvoidframe structure complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The receiving area is designed with specific geometric characteristics that match the pole's cross-section, providing localized contact and stabilization only where needed. The sliding elements are positioned strategically to maintain stability without requiring complete enclosure, balancing stability with structural simplicity.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The frame structure serves multiple functions: it provides the guiding path, supports the sliding elements, and maintains the receiving area geometry. This multi-functionality reduces the need for additional stabilization components, simplifying the overall structure while maintaining pole stabilization.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If sliding elements are arranged parallel to the longitudinal direction of the pole, then linear movement is enabled, but the risk of unintended hooking increases

Engineering Contradiction:
Improvelinear movement capabilityVSAvoidunintended hooking
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The sliding elements are designed with asymmetric geometry where the contact section is parallel to the pole's longitudinal direction for linear movement, while the end section is angled away from the receiving area. This asymmetric design prevents unintended hooking by creating a geometric mismatch that allows the element to slide freely in the guide direction while blocking reverse engagement.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The angled end sections of the sliding elements are designed in advance to prevent unintended hooking before it can occur. The angle is specifically configured to counteract any tendency for the sliding elements to engage with the pole in a harmful manner, proactively eliminating this risk while maintaining linear movement capability.

Inventive Principle:
Principle #9Preliminary anti-action
