Solution Overview

Problem

Conventional roller holders for glass processing and conveying systems require multiple types for thick and thin glass sheets, complicating maintenance due to different designs, and there is a need for a versatile roller holder that can be used in both thick and thin slabs of support walls.

Innovation Solution

A roller holder with varying retaining elements, including distal and proximal elements at different distances from the open end, allowing secure mounting on both thick and thin plates, featuring spring-loaded tongues for elastic retention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If different roller holder designs are used for thick and thin glass sheets, then secure mounting is achieved for each specific thickness, but device complexity and maintenance difficulty increase

Engineering Contradiction:
Improvesecure mountingVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The roller holder is designed with multiple retaining elements at different distances from the open end, allowing a single holder design to securely mount on support walls of varying thicknesses. The retaining elements can engage with the back of thin or thick panels, providing universal applicability across different glass sheet processing applications without requiring multiple specialized holder types.

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

2Adaptability or versatility

If multiple roller holder types are used in the same plant, then specific mounting requirements are met, but maintenance becomes more difficult

Engineering Contradiction:
Improveadaptability to different thicknessesVSAvoidmaintenance difficulty
Core Design Contradiction:
Adaptability or versatilityVSEase of repair

Solution Approach 1:

By incorporating retaining elements at multiple positions along the roller holder body, a single holder design can adapt to both thin and thick support wall panels. This standardization means maintenance personnel only need to be familiar with one roller holder type, significantly easing repair and replacement procedures while maintaining adaptability across different mounting scenarios.

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

Solution Approach 2:

The retaining elements are designed to be elastically movable, allowing them to flex during insertion and then spring into position to engage with the back of the support wall panel. This dynamic characteristic enables the same holder design to accommodate varying panel thicknesses while maintaining secure engagement, simplifying both installation and maintenance operations.

Inventive Principle:
Principle #15Dynamics

3Ease of manufacture

If retaining elements are positioned at a fixed distance from the open end, then simple design is achieved, but adaptability to different plate thicknesses is reduced

Engineering Contradiction:
Improvedesign simplicityVSAvoidadaptability to plate thickness
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The roller holder incorporates multiple retaining elements positioned at different distances from the open end, effectively segmenting the retention function across multiple locations. This segmentation allows the holder to engage with support walls of various thicknesses, with appropriate retaining elements selecting themselves based on the panel thickness, thereby achieving versatility without significantly complicating the manufacturing process.

Inventive Principle:
Principle #1Segmentation

AI summary

In a roller (1) with a roller holder (2) intended for use in support walls for insulating glass and/or flat glass systems, retaining elements (8, 9) are provided on the roller holder (2) at different distances from the open end (6) of the roller holder (2) over which the roller (1) projects outwards. First, distal retaining elements (8), acting like latches, are for securing the roller holder (2) in a thicker plate (20), and further, proximal retaining elements (9) are for securing the roller holder (2) in a thinner plate (14). Four additional, proximal retaining elements (9), acting like latches, are provided and project elastically outwards from opposite longitudinal sides (3) of the roller holder (2). The first, distal retaining elements (8) project elastically outwards from the transverse sides (4) of the roller holder (2).
