Solution Overview

Problem

Existing apparatuses for treating molded objects are complex and costly due to the need for multiple holding bolts of different lengths to accommodate objects of varying sizes, requiring complicated adjustments and component replacements.

Innovation Solution

The apparatus features movable conveyor strands with extendable connecting elements and pivot bearings, allowing the same holding bolts to be used for objects of different lengths, enabling efficient and precise conveyance through treatment stations without the need for multiple bolt lengths.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple holding bolts of different lengths are used to accommodate molded objects of varying sizes, then the apparatus can handle different object lengths, but the device complexity and cost increase due to needing to keep and manage multiple bolt types

Engineering Contradiction:

Improveability to handle different object lengthsVSAvoidcomplexity of managing multiple holding bolt types

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies universality by designing a single holding bolt that can accommodate molded objects of different lengths. The holding bolt includes an adjustable connecting element that can be positioned at different locations along the bolt's length, allowing one bolt type to serve multiple functions for various object sizes, thereby eliminating the need to maintain multiple bolt inventories.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent applies dynamics by making the connecting element position adjustable rather than fixed. The connecting element can be moved along the holding bolt and secured at different positions, enabling the same holding bolt to adapt dynamically to different molded object lengths, thus resolving the contradiction between versatility and device complexity.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If the drive chain is widened to accommodate molded objects of different lengths, then the apparatus can handle varying object sizes, but the adjustment process becomes complicated and time-consuming

Engineering Contradiction:

Improveability to accommodate different object lengthsVSAvoidease of adjusting the drive chain

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent applies dynamics by making the connecting element position adjustable on the holding bolt. Instead of widening the entire drive chain, only the connecting element position needs to be changed, which is a simpler and faster adjustment that maintains ease of operation while providing adaptability to different object lengths.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent applies segmentation by separating the adjustment function from the entire drive chain. Only the connecting element portion of the holding bolt needs to be adjusted or replaced, rather than adjusting the whole drive chain width. This segmented approach simplifies the adjustment process and reduces the time required to accommodate different object sizes.

Inventive Principle:

Principle #1Segmentation

3Reliability

If different-length holding bolts are used for stability reasons, then the molded objects can be conveyed stably, but the quantity of different holding bolts that must be kept increases

Engineering Contradiction:

Improvestability of molded object conveyanceVSAvoidnumber of different holding bolt types to maintain

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An apparatus for treating molded objects all having a predetermined object length in a treatment station has first and second transversely spaced conveyor strands extending longitudinally in a travel direction into the treatment station for displacing the object in the travel direction into the treatment station. Respective first and second holding bolts are supported by the respective strands and secured in respective ends of the objects with the objects extending transversely between the strands. A plurality of longitudinally spaced and transversely extending support elements are fixed to and longitudinally displaceable with the first strand. The first bolts are supported on the elements that each have a transverse length equal to at least 30% of the length of the first holding bolt between the respective end of the respective molded object and the first conveyor strand, or 10% of the length of the molded objects, or 30 mm.
