Solution Overview

Problem

Existing gutter forming apparatus face challenges with dimensional and shape deviations due to independently adjustable components, leading to misalignment and time-consuming alignment processes, which affect the quality and reliability of the end product and require skilled intervention for repairs.

Innovation Solution

A subframe with laterally spaced side walls and fixed relationships between components, ensuring precise alignment of driven and guide keel rollers, allowing for quick assembly and maintenance without complex adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If independently adjustable components are used, then adaptability is improved, but manufacturing precision deteriorates due to misalignment

Engineering Contradiction:

Improveadjustability of componentsVSAvoidalignment of rollers

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The apparatus is divided into a main frame and a subframe assembly. The subframe contains the driven and guide keel rollers mounted on a separate structure that can be independently positioned and adjusted relative to the main frame, allowing precision alignment without affecting the entire apparatus.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The subframe acts as an intermediary structure between the main frame and the rollers. It provides a stable mounting platform with adjustment mechanisms that enable precise positioning of the rollers while maintaining their functional independence and adaptability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple independently adjustable components are used, then adaptability is improved, but device complexity increases

Engineering Contradiction:

Improveindependent adjustment capabilityVSAvoidnumber of adjustment mechanisms

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple adjustment functions are combined into the subframe structure. The subframe integrates mounting positions, alignment mechanisms, and support functions into a single modular assembly, reducing the overall complexity compared to having independent adjustment mechanisms for each roller mounted directly to the main frame.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of operation

If independent adjustment of components is allowed, then ease of operation is improved, but reliability deteriorates due to alignment deviations

Engineering Contradiction:

ImproveadjustabilityVSAvoidconsistency of product quality

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The subframe is pre-configured with precise mounting positions and alignment features during manufacturing. This preliminary precision setup ensures that when the apparatus is assembled and operated, the rollers maintain consistent alignment, reducing variability in product quality while still allowing operational adjustments.

Inventive Principle:

Principle #10Preliminary action

AI summary

An apparatus for shaping a formable sheet advancing in a travel path has a main frame and a unitary subframe on the main frame. Driven and guide keel rollers are operatively mounted to the subframe so that there is a predetermined relationship between turning axes on the driven and guide keel rollers. Sheet shaping assemblies progressively shape a sheet advanced by the driven keel rollers.
