Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tilting mechanisms for electronic devices, such as televisions, lack adjustable and secure mounting solutions that allow for easy tilt adjustments without manual actuation of locking mechanisms, often requiring tools and being sensitive to the weight of the device.
Innovation Solution
A tilting support mechanism comprising a head portion, an undercarriage portion, and a telescopic portion with a ratcheting locking mechanism that allows for manual adjustment in one direction without actuation and requires actuation for adjustment in another direction, enabling secure and easy tilt angle changes between 0 and 30 degrees.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional tilting mechanism is used, then the device can be mounted on a wall, but manual actuation of locking mechanisms and tools are required for tilt adjustments
Solution Approach 1:
The telescopic portion automatically locks into different positions based on the weight of the electronic device and gravitational force, eliminating the need for manual actuation of locking mechanisms. The system serves itself by using the device's weight to engage locking notches at appropriate tilt angles.
Solution Approach 2:
The patent replaces traditional mechanical locking mechanisms requiring tools and manual actuation with a gravity-based telescopic system. The mechanical system uses gravitational force and the device's weight to automatically lock and unlock positions, substituting complex manual locking mechanisms with a simpler gravity-driven system.
2Reliability
If a secure locking mechanism is implemented, then the electronic device is held firmly, but adjustment requires intentional unlocking which reduces flexibility
Solution Approach 1:
The locking mechanism transitions from a static locked state to a dynamic adjustable state based on user interaction. When the user applies force to tilt the device, the telescopic portion dynamically transitions between locked positions, providing both stability during normal operation and flexibility during adjustment.
Solution Approach 2:
The mechanism预先 engages locking notches to prevent unwanted movement and maintain stability. The locking features are designed to automatically engage at specific positions, providing preliminary stabilization before the user needs to make adjustments, thus preventing accidental tilts while allowing intentional adjustments.
3Ease of operation
If the tilting mechanism allows easy adjustment, then user convenience is improved, but the mechanism becomes sensitive to device weight
Solution Approach 1:
The patent designs the telescopic portion and locking notches to accommodate a range of device weights. The mechanism's parameters such as spring force, friction characteristics, and notch geometry are optimized to provide automatic locking across different weight scenarios, making the system adaptable rather than sensitive to specific weight values.
4Measurement precision
If manual actuation of locking mechanism is required, then precise control is achieved, but time and effort are consumed
Solution Approach 1:
The system automatically determines and locks into the appropriate tilt angle position based on the device weight and gravitational force, eliminating the time-consuming process of manual locking. The self-service mechanism quickly engages the correct locking notch without requiring user intervention for each adjustment.
Solution Approach 2:
The locking notches are pre-positioned at optimal tilt angles, and the telescopic portion is designed to automatically engage these pre-determined positions. This preliminary arrangement of locking features eliminates the need for time-consuming manual alignment and locking operations.
