Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laptop computers lack adjustability in the angle of their keyboards, leading to ergonomic discomfort and potential user fatigue due to their integrated and non-portable design.
Innovation Solution
An electronic device with an automatic elevating assembly using an electromagnetic unit and magnetic elements that allows the rear end of the electronic part (such as the keyboard) to be selectively lifted or retracted with one-click control, utilizing a combination of repulsion and attraction forces to adjust the angle without occupying extra space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the keyboard is made integrated into the laptop housing for portability, then the device maintains integrity and portability, but the keyboard angle becomes fixed and non-adjustable causing ergonomic discomfort
Solution Approach 1:
The patent replaces traditional mechanical adjustment mechanisms (hinges, screws, levers) with an electromagnetic unit that uses magnetic attraction and repulsion forces to adjust the keyboard angle. This substitution reduces mechanical complexity while enabling smooth, controlled movement between fixed angular positions.
Solution Approach 2:
The elevating assembly is divided into distinct functional components: an electromagnetic unit with first and second components, magnetic elements positioned at specific locations, and a support piece. This segmentation allows each component to perform its specific function independently, simplifying the overall system while maintaining adjustability.
2Ease of operation
If a rotatable support is added to the keyboard back for angle adjustment, then keyboard ergonomics are improved, but the device loses portability and integrated design
Solution Approach 1:
The elevating assembly is fully integrated into the laptop housing structure. The electromagnetic unit, magnetic elements, and support piece are combined with the housing and keyboard assembly, creating a unified design that maintains portability while adding ergonomic adjustment capability.
Solution Approach 2:
The support piece acts as an intermediary component between the keyboard and housing, providing the connection point for angle adjustment. It includes a magnetic element that interacts with the electromagnetic unit, enabling controlled movement without requiring external or add-on components.
3Ease of operation
If an electromagnetic unit with multiple components is used for angle adjustment, then precise control and smooth movement are achieved, but the device complexity increases
Solution Approach 1:
The electromagnetic unit serves multiple functions: it provides both attraction and repulsion forces to move the keyboard between different angular positions, acts as a positioning mechanism, and enables precise control. This multi-functionality reduces the need for separate mechanisms for each function.
Solution Approach 2:
The system controls keyboard positioning by changing the magnetic field parameters - switching between attraction and repulsion modes of the electromagnetic unit. This allows precise control over the keyboard angle by adjusting electromagnetic field strength and polarity rather than using mechanical positioners.

AI summary
In an electronic device, a lift structure, composed by electromagnets, magnetic components, and support piece, is disposed at a rear end of an electronic part and a housing. The magnetic components can be permanent magnets and disposed at the rear end of the electronic part and the support piece. The electromagnets are controlled by driving device to a configuration so as to have repulsion and attraction to the rear end and to the support piece respectively, thereby configuring the rear end to a lifted position, or to another configuration so as to have attraction and repulsion to the rear end and to the support piece respectively, thereby configuring the rear end to a retracted position. An adjusting component is further used to adjust the position of the electromagnet to determine the height of the rear end of the electronic part when set in the lifted position.
