Solution Overview

Problem

Existing glass panel installation systems face challenges such as difficult and time-consuming installation, lack of precision in clamping force, potential damage to components, and safety risks due to the need for installers to lean over installed railings to install weather seals, as well as issues with removing stuck taper plates.

Innovation Solution

A revised base shoe with a dovetail groove for pre-installation of weather seals and a continuous setting strip replacing individual spacers, along with taper plates featuring a continuous projection for easy removal, enhance safety and efficiency by requiring weather seals to be installed before panel insertion and allowing for easier plate separation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If weather seals are installed after glass panel insertion, then installation flexibility is maintained, but installer safety deteriorates due to leaning over installed railings

Engineering Contradiction:
Improveinstallation flexibilityVSAvoidinstaller safety
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The base shoe is designed with a pre-formed recess that accommodates the weather seal before the glass panel is installed. This preliminary configuration of the base shoe allows the weather seal to be positioned in advance, eliminating the need for installers to lean over completed railings and thereby resolving the safety hazard while maintaining installation flexibility

Inventive Principle:
Principle #10Preliminary action

2Stability of the object's composition

If taper plates are driven tightly to secure panels, then panel stability improves, but plate removal difficulty increases due to sticking

Engineering Contradiction:
Improvepanel stabilityVSAvoidplate removal
Core Design Contradiction:
Stability of the object's compositionVSEase of repair

Solution Approach 1:

The taper plate incorporates a localized release feature at its base that creates a differential between the clamping interface and the removal interface. This local quality change allows the plate to maintain strong engagement with the panel during service while enabling easy separation during maintenance, resolving both the stability and removal difficulty concerns

Inventive Principle:
Principle #3Local quality

3Object-affected harmful factors

If individual spacers are used to prevent glass contact, then panel protection is achieved, but installation time increases due to multiple placement steps

Engineering Contradiction:
Improvepanel protectionVSAvoidinstallation time
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

Multiple individual spacers are merged into a single continuous setting strip that is pre-installed in the base shoe. This consolidation maintains the protective function of preventing glass contact with the base shoe while eliminating the need to individually place multiple spacers, thereby significantly reducing installation time

Inventive Principle:
Principle #5Merging (Combining)

AI summary

An improved base shoe 12 for use with the panel installation and removal system described in U.S. Patents Nos. 8,122,654 and 8,201,366 is presented. The improved base shoe 12 featuring dovetail grooves 22 for use with a safety-seal weather seal 24, wherein the safety-seal weather seal 24 must be installed prior to installing a glass panel 30. The safety-seal weather seal 24 eliminates a safety risk incurred by installers who attempt to install a press in seal 26 at an outboard base shoe to glass panel interface of an installed panel 30 and base shoe 12. In an alternative embodiment, the improved base shoe 12 features a recess 66 for use with taper plates 62 having a continuous projection 64 along an upper surface. The base shoe 12 and taper plates 62 are configured so as to provide a prying surface between the projection 64 on the taper plates 62 and a wall 18 of the base shoe 12.
