Height-Adjustable Desk-Type Electric Piano with Telescopic Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electric pianos have fixed support frames, which cannot be adjusted to accommodate users of different heights, leading to uncomfortable playing positions and limiting their use as both a musical instrument and a desk.
Innovation Solution
A height-adjustable desk-type electric piano is designed with a bracket body and a desk-type keyboard assembly, featuring a screw adjustment device that allows the bracket body to be lifted or lowered, enabling the piano frame to be adjusted to various heights and integrated with a desk function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the support frame height is fixed for simple structure, then the structure is simple and stable, but it cannot accommodate users of different heights
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed support frame into an adjustable one. The support frame includes telescopic components with adjustable lengths, allowing the height to be dynamically changed according to different users' needs. This resolves the contradiction by making the structure adaptable while maintaining reasonable complexity through modular design.
Solution Approach 2:
The support frame is segmented into multiple telescopic components that can be independently adjusted. Each support leg consists of nested segments that can be extended or retracted, enabling height adjustment without requiring complete structural redesign. This segmentation allows adaptability while keeping each individual component relatively simple.
2Adaptability or versatility
If the electric piano is designed as a fixed-height instrument, then the manufacturing is simple, but it cannot be used as both a piano and a desk
Solution Approach 1:
The patent directly applies the universality principle by designing the electric piano with an adjustable support frame that enables dual functionality. The same structure serves as both a musical instrument stand and a desk by allowing height adjustment to accommodate different use scenarios, eliminating the need for separate furniture pieces.
Solution Approach 2:
The dynamic adjustability of the support frame enables the electric piano to transition between different functional states. By adjusting the height, the instrument can be configured for playing or for desk work, providing multi-functionality while maintaining a single integrated structure that is relatively simple to manufacture.
3Ease of operation
If the support frame is made telescopic for height adjustment, then the height can be adjusted, but the structure becomes more complex
Solution Approach 1:
The telescopic support frame employs the nesting principle where inner tubes are placed within outer tubes to achieve height adjustment. This nested structure allows compact storage when retracted and easy extension when needed, providing height adjustability while minimizing the space required and reducing overall structural complexity compared to alternative expansion mechanisms.
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
The height-adjustable design allows the electric piano to be used comfortably by individuals of varying heights, and its dual function as both a piano and a desk enhances its usability and versatility.
Implementation Method 1
the threaded rod is sleeved in the sleeve rod and in threaded connection with it, the threaded rod is screwed in and out of the sleeve rod
Implementation Method 2
the vertical gear and the disk gear are meshed and connected to each other for transmission
