Solution Overview

Problem

Existing partition systems face challenges in securely and efficiently integrating light-transmitting materials, such as glass panels, into their frameworks, often resulting in instability and potential dislodgement.

Innovation Solution

A partition system featuring a frame with connector assemblies that include movable retainers with cam surfaces and retaining surfaces, allowing a window subassembly with a light-transmitting material to be securely fastened by engaging the retainers, ensuring stability and easy installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional partition systems use fixed or simple connection methods for light-transmitting materials, then the installation process is straightforward, but the panels become unstable and prone to dislodgement

Engineering Contradiction:
Improvestability of light-transmitting material integrationVSAvoidcomplexity of connector assembly
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The connector assembly employs a movable retainer that can shift between engaged and disengaged positions, allowing the system to adapt during installation while providing secure retention when engaged. The movable retainer with cam surface enables dynamic transition from installation mode to secured mode, resolving the contradiction between ease of installation and reliability of retention.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The connector assembly is divided into separate functional components: a base structure, a movable retainer, and a cam surface mechanism. This segmentation allows each component to perform its specific function independently while working together to achieve both easy installation and secure retention of the light-transmitting material.

Inventive Principle:
Principle #1Segmentation

2Reliability

If traditional partition systems use simple connection methods, then the device complexity is low, but the panels can be easily dislodged and lack stability

Engineering Contradiction:
Improvesecurity of panel retentionVSAvoidease of installation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The movable retainer is biased toward the engaged position, allowing it to automatically secure the light-transmitting material upon insertion without requiring additional manual operations. The cam surface and bias mechanism work together to self-lock the panel in place after installation, providing secure retention while maintaining ease of installation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The movable retainer is pre-positioned and biased toward the engaged state before installation. The cam surface is designed to guide the connecting portion into the engaged position automatically, performing the retention action in advance and eliminating the need for separate securing steps during installation.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If traditional partition systems lack a specific retention mechanism, then the structure remains simple, but the light-transmitting materials are prone to dislodgement

Engineering Contradiction:
Improveprevention of dislodgementVSAvoidcomplexity of retention mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The movable retainer acts as an intermediary element between the partition frame and the light-transmitting material. It provides a dedicated retention interface that transfers and secures the material to the frame structure, preventing dislodgement while maintaining a relatively simple overall system architecture through its specialized function.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Stability of the object's composition

If traditional partition systems use basic connection methods, then the manufacturing and installation process is simple, but the integration of light-transmitting materials is unstable

Engineering Contradiction:
Improvestability of panel integrationVSAvoidease of assembly
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The movable retainer provides a dynamic connection mechanism that stabilizes the light-transmitting material during operation while maintaining ease of assembly. The retainer can move during installation to accommodate misalignment and then locks into place to provide stable integration, resolving the contradiction between assembly ease and operational stability.

Inventive Principle:
Principle #15Dynamics

AI summary

A window assembly for partition walls. The window assembly includes a plurality of connector assemblies that are configured to be connected to a partition frame around an opening through the partition frame. Each connector assembly includes a base structure and at least one movable retainer that is biased towards an engaged position. The window assembly also includes a subframe including two pairs of elongated subframe members having opposite ends that are rigidly interconnected to define a generally rectangular central opening. The subframe further defines oppositely facing inner and outer side faces. The subframe includes a connecting portion protruding away from the inner side face and engaging the movable retainer to connect the subframe to the connector assemblies. The window assembly further includes at least one sheet of light-transmitting material secured to the subframe and extending across the central opening.
