Sliding Panel Gear Release Mechanism for Manual Override
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart home devices, such as windows and doors, often lack automation capabilities, making it inconvenient to open or close them manually, especially in emergencies or when the automated system is malfunctioning, and there is a need for a mechanism that allows users to manually control automated sliding panels without damaging the motor or gear system.
Innovation Solution
An automated sliding panel mechanism featuring a motor-driven gear system with a manual release mechanism using magnets to disengage the gear from the rack, allowing users to manually open or close the panel, and a brake system to prevent backdriving and protect the motor, along with a user-friendly interface like a plate or lever for easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a motor-driven gear system is used to automate sliding panels, then automation capability is improved, but the ability to manually operate the panel is lost
Solution Approach 1:
The system is divided into two distinct operational modes: automated mode where the motor drives the gear system, and manual mode where the release mechanism disengages the gear from the rack. This segmentation allows each mode to function independently without interfering with the other, resolving the contradiction between automation and manual operation capability
Solution Approach 2:
The system dynamically transitions between engaged and disengaged states through the release mechanism. The gear can be dynamically shifted along its axis to mesh with or disengage from the rack teeth, allowing the system to adapt between automated and manual operation modes as needed
2Ease of operation
If a manual release mechanism is added to allow manual operation, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The release mechanism acts as an intermediary component that mediates between the user's manual input and the gear-rack system. By introducing this intermediate element, the patent enables manual operation without requiring complete redesign of the automated system, thus adding minimal complexity while achieving the desired functionality
Solution Approach 2:
The patent replaces complex mechanical locking systems with a magnetic holding mechanism. Magnets are used to hold the gear in engaged or disengaged positions, eliminating the need for complex mechanical springs, latches, or cam-based release mechanisms, thereby reducing overall device complexity
3Ease of operation
If the gear is allowed to move freely for manual operation, then ease of operation is improved, but the motor may be damaged by backdriving
Solution Approach 1:
The patent extracts the gear from its fixed position on the motor shaft, allowing it to move independently along the axis. This extraction enables the gear to be disengaged from the rack during manual operation, preventing backdriving forces from being transmitted to the motor while still allowing automated operation when engaged
Solution Approach 2:
The system segments the power transmission path by allowing the gear to be physically separated from the rack. This segmentation creates a clear distinction between automated operation (where power flows from motor to gear to rack) and manual operation (where the gear-rack connection is disconnected), protecting the motor from damage
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables safe and convenient manual operation of automated sliding panels in emergencies or when the automated system fails, preventing damage to the motor and gear system while providing user-friendly control over window opening and closing.
Implementation Method 1
a manual release mechanism that is adapted to move the gear along its axis of rotation from an engaged position, wherein the gear teeth mesh with the rack teeth, to a released position, wherein the gear teeth are disengaged from the rack teeth
Data Source
AI summary
An automated sliding panel mechanism is disclosed. An automated sliding panel mechanism includes a motor attached to a first component of a sliding panel that is configured to move the sliding panel between a closed position and an open position. The mechanism also includes a power source and a rack attached to a second component of the sliding panel and including a base with rack teeth extending from a plane thereof. A gear is rotated by the motor and has gear teeth shaped to mesh with the rack teeth. A manual release mechanism is adapted to move the gear along its axis of rotation, from an engaged position, wherein the gear teeth mesh with the rack teeth to a released position, wherein the gear teeth are disengaged from the rack teeth. The manual release mechanism also includes a holding mechanism adapted to hold the gear in the engaged position and in the released position as selected by a user.
