Lift-Stand Switching Mechanism for Adjustable Viewing Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable electronic devices lack flexibility in adjusting viewing angles and operation modes, leading to user fatigue due to limited adjustability and non-intuitive switching mechanisms in supporting stands.
Innovation Solution
An electronic device with a lifting mechanism and switching mechanism that allows the body to rise or drop relative to the base, enabling adjustable inclination angles and intuitive operation mode changes, featuring a switch button, lever, and locking member for locking or unlocking the body and lifting mechanism to the base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed supporting stand is used, then the structure is simple, but the viewing angle cannot be changed and operation flexibility is poor
Solution Approach 1:
The supporting stand is designed with a lifting mechanism that enables dynamic adjustment between multiple operation modes (tablet mode, notebook mode, presentation mode). The stand can transition from a fixed position to an elevated position, allowing the display to be viewed at different angles and positions, thus improving adaptability while maintaining reasonable structural complexity through controlled mechanical movement.
Solution Approach 2:
The supporting stand is divided into separate functional components including a base, a lifting mechanism with multiple links, and a display support portion. This segmentation allows each component to perform its specific function independently while working together to achieve multi-angle viewing capability, resolving the contradiction between adaptability and structural complexity.
2Adaptability or versatility
If a manual switching mechanism is used, then the device can change operation modes, but the switching process is complex and not intuitive
Solution Approach 1:
The lifting mechanism is designed to automatically transition between operation modes when the user releases the display. The mechanism uses spring-loaded links and engaging portions that self-activate based on the display's position and weight, eliminating the need for complex manual switching operations and making the mode changes intuitive and effortless.
Solution Approach 2:
The switching mechanism is pre-configured with multiple engaging portions and corresponding recesses that are positioned in advance for different operation modes. When the user lifts the display to a certain position, the mechanism automatically engages with the pre-positioned recesses, enabling seamless transitions between modes without requiring the user to understand or operate complex switching procedures.
3Ease of operation
If the lifting mechanism is always engaged, then the display is stable, but the operation flexibility and mode switching capability are reduced
Solution Approach 1:
The lifting mechanism transitions from a static always-engaged state to a dynamic state where it can be easily disengaged and re-engaged. The spring-loaded design allows the mechanism to flexibly switch between locked (stable) and unlocked (flexible) states based on user input, resolving the contradiction between stability and operational flexibility by making the engagement state changeable rather than fixed.
Solution Approach 2:
The lifting mechanism acts as an intermediary between the user's lifting action and the display's final positioned state. It provides controlled engagement and disengagement through spring-loaded links that mediate between the user's input force and the display's weight, allowing smooth transitions between stable and flexible states without sudden movements or loss of control.

AI summary
An electronic device includes a base, a lifting mechanism, a body and a switching mechanism. The lifting mechanism and the body are movably disposed at the base. The lifting mechanism is located between the body and the base, and two ends of the lifting mechanism are connected to the body and the base. The switching mechanism is disposed at the base. The switching mechanism is configured to lock the body and the lifting mechanism to the base or configured to remove a locking relationship of the body and the lifting mechanism with respect to the base. An expansion device is further provided.
