Solution Overview

Problem

Conventional end guides for folding panel systems are confusing for customers due to the need for two types, cannot be easily reconfigured for reverse use, and guide bolts tend to unwind, leading to disconnection and security vulnerabilities.

Innovation Solution

A guide assembly with a first body section and a second body section connected by cooperating mountings, allowing relative displacement and rotation, featuring a locking device and a guide bolt support with a D-shaped bore to prevent axial rotation and visible access, enabling ambidextrous operation and enhanced security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional end guides are used with threaded guide bolts, then the guide bolts can be adjusted, but the bolts may unwind due to vibration causing disconnection and security vulnerabilities

Engineering Contradiction:
Improveadjustability of guide boltVSAvoidconnection stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The guide assembly is divided into two separate body sections: a first body section that remains fixed in the channel, and a second body section that carries the guide bolt and can be displaced relative to the first. This segmentation allows the guide bolt to be adjusted during installation but prevents it from unwinding during operation, as the threaded connection is maintained within the secured second body section.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The guide assembly transitions from a static fixed connection to a dynamic adjustable connection. The second body section can be displaced relative to the first body section to adjust the guide bolt position, then locked into place. This dynamic adjustment capability resolves the contradiction by allowing ease of operation during installation while maintaining reliability during operation.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If guide bolts with HEX profiles are used, then the bolts can be wound in and out, but the visible HEX drive makes the door vulnerable to break-in

Engineering Contradiction:
Improvebolt adjustment capabilityVSAvoidsecurity vulnerability
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The visible HEX drive feature is extracted from the external view of the guide assembly. The guide bolt is positioned within the second body section, and the adjustment mechanism is concealed within the channel structure. This removes the security vulnerability while preserving the ease of operation during installation, as the bolt can still be adjusted through the channel access point but is not visible from the exterior.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The channel structure serves as an intermediary that provides access for adjusting the guide bolt during installation while preventing external access during operation. The channel acts as a mediator between the adjustment mechanism and the external environment, allowing adjustment capability while blocking the visible HEX drive from being accessible to potential intruders.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If end guides are designed for specific handedness, then the guide structure is optimized, but customers face confusion and the guide cannot be reconfigured for reverse use

Engineering Contradiction:
Improveguide structure optimizationVSAvoidreconfiguration capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The guide assembly is designed with universal adaptability through the two-body section structure. The second body section can be displaced relative to the first body section to accommodate different handedness configurations. This multi-functionality allows a single guide assembly design to serve multiple purposes (left-handed and right-handed installations) while maintaining the optimized guide structure for each configuration, thereby resolving the contradiction between structural optimization and adaptability.

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

AI summary

A guide assembly for a folding panel assembly or system, the guide assembly including a first body section for locating the assembly in a guide channel and a second body section for carrying a bolt that passes through a hinge for attachment to a folding panel, wherein the second body section is pivotally mounted to the first body section so as to adopt either a left or right handed orientation relative to the first body section.
