Spring-Driven Door Opener with Damping Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Side opening furniture doors are inconvenient to open and close, often causing collisions with users, especially children, due to the need for handles or similar structures, and the existing mechanisms do not effectively manage closing speed to prevent noise or harm.
Innovation Solution
A device comprising a shell with a pushing mechanism driven by springs, which allows the door to be opened by a gentle press, eliminating the need for handles and incorporating a damper to control closing speed and reduce noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a handle or similar structure is installed on the door for easy opening, then the ease of operation is improved, but the harmful factors increase due to collision risk with users, especially children
Solution Approach 1:
The patent removes the handle from the door system entirely. Instead of providing a traditional handle for manual pulling, the invention uses a pushing mechanism where the user simply pushes the door body to trigger the automatic opening function, thereby eliminating the protruding handle that causes collision hazards
Solution Approach 2:
The door opening system operates automatically once triggered. The spring-driven mechanism self-activates the door opening sequence without requiring continuous manual intervention through a handle. The user only needs to initiate the action by pushing the door, and the system completes the opening function autonomously
2Device complexity
If the door is equipped with a traditional hinge mechanism, then the structural simplicity is maintained, but the closing speed is too fast causing noise and potential harm to users
Solution Approach 1:
The patent incorporates a damper mechanism that pre-establishes resistance to the door's closing motion. This damper counteracts the excessive closing speed generated by the hinge, cushioning the closing action to reduce noise and prevent harmful collisions with users before they occur
Solution Approach 2:
The damper acts as an intermediary element between the hinge and the door. It mediates the closing force generated by the hinge, transforming the potentially harmful fast closure into a controlled, slower movement that is safe for users while maintaining the overall simplicity of the door mechanism
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
Facilitates easy opening and closing of side opening doors without handles, preventing user collisions and minimizing noise and damage from fast closure speeds.
Implementation Method 1
One end of a driving device, which has one or more springs, drives the pushing device to rotate via a rotating member
Implementation Method 2
The above technical solution also has a damper. When the hinge pushes the door to close, the damper slows down the closing speed of the door

AI summary
This invention discloses a door opener, comprising a shell consisting of an upper cover plate (1) and a lower cover plate (2). The key is that a pushing device for pushing the door to rotate is provided in the shell. An end of a driving device, which has one or more springs, can drive, via a rotating member (3), the pushing device to rotate. A locking/releasing device, which cooperates with the driving device, is provided at the other end of the driving device. The structure of this invention is unique. It allows the door to be conveniently opened and will not cause any possible harm to the users.
