Sealing corner bracket for receiving two frame members and cabinet including corner bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fiber optic equipment cabinets with seamless single-piece shells are not scalable, leading to manufacturing inefficiencies, difficulty in transportation and installation, and challenges in repair and modification to meet varying capacity requirements.
Innovation Solution
The use of corner brackets that provide structural support and a dust- and fluid-resistant seal, allowing for the assembly of cabinets on-site and enabling scalability by adjusting the frame members and brackets to accommodate different dimensions and capacity needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a seamless single-piece shell construction is used for the cabinet, then the cabinet provides a sealed environment that prevents moisture and dust entry, but the cabinet becomes non-scalable and difficult to manufacture in different sizes
Solution Approach 1:
The cabinet is divided into multiple modular components including corner brackets, frame members, and panels that can be assembled together. The corner brackets serve as standardized connection elements that enable different cabinet configurations and sizes while maintaining sealed joints through integrated sealing mechanisms.
2Strength
If a seamless single-piece shell construction is used for the cabinet, then the cabinet provides structural integrity, but the cabinet becomes cumbersome to transport and install
Solution Approach 1:
The cabinet structure is segmented into smaller modular components that can be easily transported and assembled on-site. The corner brackets and frame members are designed as discrete elements that combine to form the complete cabinet structure, facilitating convenient handling and installation.
Solution Approach 2:
Multiple functional elements are combined into integrated components. The corner brackets incorporate both structural support functions and sealing functions in a single element, while frame members integrate connection features and structural geometry, reducing the number of separate parts to transport.
3Stability of the object's composition
If a seamless single-piece shell construction is used for the cabinet, then the cabinet provides a unified structure, but the cabinet becomes difficult to repair or replace damaged portions
Solution Approach 1:
The cabinet is constructed from modular components including corner brackets, frame members, and panels that can be independently accessed and replaced. This segmentation enables localized repair of damaged portions without requiring replacement of the entire cabinet structure.
Solution Approach 2:
Damaged components such as corner brackets or panels can be extracted and removed from the cabinet assembly independently. The modular design with standardized connection interfaces allows for easy removal and replacement of individual elements while maintaining the integrity of the remaining structure.
4Adaptability or versatility
If different sized cabinets are manufactured to meet varying capacity requirements, then the cabinet can be tailored to specific needs, but manufacturing and inventory inefficiencies occur
Solution Approach 1:
The corner brackets and frame members are designed as universal standardized components that can be used across different cabinet sizes and configurations. This modularity allows a limited set of components to be assembled into various cabinet dimensions, eliminating the need to manufacture completely different cabinet types for different capacity requirements.
Solution Approach 2:
The cabinet system is segmented into standardized modular components that can be combined in different quantities and arrangements to create cabinets of varying sizes. This approach enables customization of cabinet capacity while maintaining efficient manufacturing processes through repeated use of standard parts.

AI summary
A comer bracket (14) may include first and second retainers (132,134) configured to receive respective ends of first and second frame members, such that the first and second frame members are substantially perpendicular with respect to one another. The first and second retainers (132,134) may include structural and sealing portions (102,104), wherein the structural portion (102) includes a first material and the sealing portion (104) includes a second material, with the first material being relatively more rigid than the second material, and the second material being relatively more elastic than the first material. The comer bracket (14) may also include first and second exterior surfaces (136,140) at least partially including the second material and first and second door panel interfaces (138,142) configured to provide a seal between the first and second exterior surfaces (136,140) and interior surfaces of first and second door panels in a closed position. The comer bracket (14) may be incorporated into a frame for a cabinet.
