Door Grille Connector with Pivot Pin for Removable Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a connector that allows a grille to be attached to a door in a removable and pivotable manner, specifically designed to engage with a preexisting door insert, providing a decorative and functional solution for various door types.
Innovation Solution
A connector system that includes a door insert with screw bosses and connector holes, allowing for the attachment of a grille that can be pivoted for access, using tubular extensions and fasteners to secure the grille to the door insert, enabling easy installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a grille is permanently attached to a door, then structural stability is improved, but ease of maintenance and adaptability deteriorate
Solution Approach 1:
The connector is divided into separate components: a first portion that attaches to the door insert and a second portion that attaches to the grille. These portions are connected through a removable pin mechanism, allowing the grille to be segmented from the door while maintaining stable attachment when connected. This segmentation enables easy removal for maintenance while providing structural stability during normal use.
Solution Approach 2:
The connector transitions from a static permanent attachment to a dynamic removable attachment. The pin can be inserted and removed to change the state of connection between the grille and door, providing both stable attachment when needed and easy removal for maintenance. This dynamic capability resolves the contradiction between structural stability and ease of maintenance.
2Adaptability or versatility
If a custom attachment system is designed for each door type, then adaptability is improved, but device complexity increases
Solution Approach 1:
The connector is designed with universal adaptability through the door insert interface. The first portion of the connector attaches to a standardized door insert that can be installed in various door types, allowing a single connector design to work across multiple door configurations. This universal approach provides adaptability without requiring complex custom designs for each door type.
Solution Approach 2:
The door insert serves as an intermediary component between the door and the connector. Rather than designing the connector to directly interface with various door types, the standardized door insert mediates this connection, simplifying the connector design while maintaining adaptability to different door configurations.
3Ease of repair
If a grille is made removable for maintenance, then ease of maintenance is improved, but structural stability and security worsen
Solution Approach 1:
The connector is pre-designed with a secure pin-and-hole engagement mechanism that provides robust structural stability when assembled. The pin fits into aligned holes in the door insert and grille, creating a strong mechanical connection that maintains reliability during normal use. This preliminary design ensures that the removable connection still provides adequate structural stability while enabling easy maintenance when the pin is removed.

AI summary
A connector for connecting a grille to a door. The connector can include a first plate connected to a second plate at a right angle. A first tubular can extend at a right angle from the first plate for inserting into a door insert frame, such as in a screw boss. The first tubular can have a hole for receiving a fastener and fastening the connector to a door. A second tubular can be disposed proximate an intersection of the first plate and the second plate. The second tubular can have a hole extending at a right angle to the hole of the first tubular for receiving a pin that can be used to connect a grille to the connector.
