Door Handle Engagement Arm for Self-Closing Door Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles and robots face challenges in navigating through self-closing doors, as these doors automatically close after opening, requiring apparatuses to maintain them in an open position for navigation.
Innovation Solution
A door control apparatus mounted on vehicles, equipped with a processor, frame, door control arm, and interaction arms, which identifies doors, unlocks them using a curved door handle contact protrusion, and holds them open using force sensors and cameras for efficient navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a door control apparatus is used to autonomously open self-closing doors, then navigation efficiency is improved, but device complexity increases
Solution Approach 1:
The door control apparatus is divided into distinct functional modules: a door handle contact protrusion for engaging the door handle, door interaction arms for pushing/pulling the door, and a processor for controlling the operations. This segmentation allows each component to perform its specific function efficiently while simplifying the overall system design and maintenance.
Solution Approach 2:
The door control apparatus is designed to handle multiple types of door operations (pushing, pulling, handling different door handles) using a unified structure. The door interaction arms can adapt to different door types, and the processor manages various navigation scenarios, making the apparatus universally applicable across different environments without requiring multiple specialized devices.
2Reliability
If the door control apparatus maintains doors open for navigation, then passage safety is improved, but energy consumption increases
Solution Approach 1:
The door control apparatus operates in periodic cycles: it opens the door, maintains it open only for the duration necessary to pass through, and then closes it. The processor monitors the navigation progress and controls the door interaction arms to hold the door open only during the critical passage period, rather than maintaining it open continuously, thereby reducing energy consumption while ensuring safety during the essential navigation window.
