Foldable Piano Keyboard With Hinge Power Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable piano keyboards lack a compact and efficient design for storage and transportation, as they are typically bulky and require multiple components, making them difficult to move and set up.
Innovation Solution
A foldable piano keyboard that separates into two equal keyboard halves, each with approximately half the keys of a standard 88-key piano, connected via a hinge with power and electronic signal transmission interfaces, allowing for easy assembly and disassembly, and featuring removable pins for secure connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a standard 88-key piano keyboard is made portable, then it can be moved and set up more easily, but it becomes bulky and requires multiple components
Solution Approach 1:
The keyboard is divided into two separate halves, each containing approximately half of the 88 keys. These halves can be independently handled and stored, yet when joined together via the hinge mechanism, they form a complete keyboard with full 88-key functionality, resolving the contradiction between portability and component complexity.
Solution Approach 2:
The two keyboard halves are designed to connect through a hinge that integrates multiple functions: mechanical connection for structural integrity, power transmission through electrical contacts, and electronic signal transmission. This merging allows the separate halves to function as a unified instrument when assembled.
2Adaptability or versatility
If a portable piano keyboard uses multiple components for flexibility, then it can be adapted to different configurations, but it requires more equipment pieces and longer setup time
Solution Approach 1:
The hinge mechanism enables dynamic reconfiguration of the keyboard system. The keyboard can be assembled by simply connecting the two halves through the hinge, which automatically establishes mechanical, electrical, and electronic connections. This dynamic assembly process significantly reduces setup time compared to traditional multi-component portable keyboards that require separate connection steps for each component.
3Volume of moving object
If the keyboard is made foldable into a compact unit, then it occupies less storage space, but it requires a complex hinge mechanism with multiple connection interfaces
Solution Approach 1:
The hinge is designed as a multi-functional component that simultaneously provides mechanical articulation for folding, electrical power transmission through integrated contacts, and electronic signal transmission. This universal design consolidates multiple functions into a single mechanism, achieving compact foldability without proportionally increasing overall system complexity.
4Stability of the object's composition
If the keyboard halves are permanently connected for stability, then the structure is more rigid, but it cannot be folded for transport or storage
Solution Approach 1:
The keyboard is segmented into two halves connected by a hinge rather than being a single rigid unit. This segmentation allows the keyboard to maintain structural stability when assembled (with the hinge providing sufficient rigidity for playing) while enabling folding capability for transport and storage, resolving the contradiction between structural rigidity and adaptability.
