Glass Panel Wire Exit Structure for Stable Terminal Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glass panel units face issues with electric wires disconnecting due to external terminals being easily movable relative to the glass panel units, leading to disconnection of connecting portions.
Innovation Solution
A glass panel unit design that includes a first and second glass panel, a frame-shaped seal, and electric wires extended through connecting voids in the panels, ensuring the wires do not protrude and thus reducing the likelihood of disconnection by integrating them within the panel structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electric wires are extended from the end surface of the glass panel unit, then external terminals can be connected, but the connecting portion becomes easily movable and disconnected
Solution Approach 1:
The patent transitions the wire exit position from the end surface (one-dimensional edge) to the side surface (two-dimensional face) of the glass panel unit. This dimensional change allows terminals to be connected on the side surface while the wire protrusion is minimized, reducing relative movement and disconnection risk while maintaining connectivity functionality
2Adaptability or versatility
If electric wires protrude from the glass panel unit, then external connections are enabled, but the connecting portion is prone to disconnection due to easy relative movement
Solution Approach 1:
The patent applies local quality by creating a specific protrusion structure at the wire exit point on the side surface. The protrusion is designed with specific dimensional characteristics (smaller than the terminal connection area) to provide localized support and reduce relative movement, while maintaining the overall connection capability

AI summary
Provided is a glass panel unit that reduces the chances of an electric wire extended being disconnected. A glass panel unit includes a first panel, a second panel, a seal, a connecting void, and an electric wire. The first panel includes a first glass pane. The second panel includes a second glass pane and is arranged to face the second glass pane. The seal has a frame shape and hermetically bonds respective peripheral edge portions of the first panel and the second panel to create an internal space between the first panel and the second panel. The connecting void is provided for a portion, other than a portion facing the internal space, of at least one of the first panel or the second panel. The electric wire is extended from the internal space to the connecting void by passing through the seal.
