Solution Overview

Problem

Existing apparatuses for transporting devices along tall constructions, such as chimneys, fail to ensure precise positioning of devices like pilot flames due to non-constant shapes and tapered sections, leading to suboptimal functioning and maintenance challenges.

Innovation Solution

An apparatus with a rail system and an oscillating frame that allows for precise positioning of devices at the terminal portion of the construction, using a pulley and cam mechanism to adjust the frame's orientation and ensure correct alignment without requiring detailed rail design studies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a carriage with wheels sliding on a vertical rail is used to transport devices along chimneys, then maintenance operations can be performed without operators going to the top of the chimney, but the correct positioning of the device at the terminal portion cannot be guaranteed due to non-constant shapes and tapered sections

Engineering Contradiction:
Improvemaintenance accessibilityVSAvoiddevice positioning precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent introduces an oscillating frame that can rotate about a horizontal axis, transforming the static rail-carriage system into a dynamic one. The frame's ability to oscillate between operative and non-operative positions allows the device to be precisely positioned at the terminal portion while maintaining ease of operation through ground-based control. This dynamic adjustment resolves the contradiction by enabling both accessible maintenance and precise positioning despite varying chimney geometries.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent adds a rotational degree of freedom to the traditional linear rail system by introducing the oscillating frame mechanism. This dimensional change allows the device to accommodate non-constant shapes and tapered sections of the chimney while maintaining precise positioning capability. The frame's rotation about a horizontal axis creates a new dimension of adjustment that compensates for geometric variations in the chimney structure.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If the rail configuration is designed to accommodate non-constant shapes and tapered sections, then detailed design studies are required, but optimal positioning of the device still cannot be ensured

Engineering Contradiction:
Improveadaptability to non-constant sectionsVSAvoiddevice positioning precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

Rather than designing complex static rails to accommodate varying chimney geometries, the patent employs a dynamic oscillating frame that can adapt its position. The frame's rotational capability allows it to compensate for non-constant shapes and tapered sections without requiring detailed design studies of each specific geometry. This dynamic approach provides both adaptability and positioning precision simultaneously.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the operational parameters of the transport system by introducing angular adjustment capability through the oscillating frame. Instead of fixing the rail geometry to match the chimney shape, the system allows the frame angle to vary, providing adaptability to different geometries while maintaining precise device positioning through controlled oscillation to predetermined positions.

Inventive Principle:
Principle #35Parameter changes

3Measurement precision

If operators access the terminal portion of the construction for maintenance, then device positioning can be visually verified, but the operation becomes dangerous and expensive due to high height and strong flames

Engineering Contradiction:
Improvepositioning verification accuracyVSAvoidsafety risks from height and flames
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The oscillating frame mechanism enables self-verification of device positioning through its controlled oscillation to predetermined positions. The system inherently provides positioning accuracy through its mechanical design and control mechanism, eliminating the need for operator intervention at heights. The device positions itself correctly through the frame's oscillation, providing both safety and verification capability.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the manual visual verification method with a mechanical control system that automatically positions the device at predetermined locations. The oscillating frame's controlled motion substitutes for operator judgment and visual assessment, providing consistent positioning accuracy without exposing operators to dangerous conditions of height and strong flames.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
