Keyboard Assembly via Internal Positioning Parts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing keyboard instrument assembly methods are inefficient and aesthetically unsatisfactory, as they require complex screwing processes and visible fastening members, which can compromise key operation comfort and instrument design.
Innovation Solution
A method for assembling a keyboard instrument that involves a keyboard unit with a key-connecting part and fastening members, where the upper and lower cases are fixed together using a secure fastening mechanism that minimizes visible fastening elements and simplifies the assembly process, allowing for comfortable key operation and design advantages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the upper case and lower case are fixed together using traditional screwing processes with visible fastening members, then the assembly is secure, but the aesthetic appearance deteriorates and key operation comfort is compromised
Solution Approach 1:
The patent extracts the fastening function from visible external fasteners and relocates it to internal positioning parts. The positioning parts are inserted into insertion holes to secure the upper and lower cases, eliminating the need for visible screw fasteners and maintaining aesthetic appearance while ensuring assembly security.
Solution Approach 2:
The patent introduces positioning parts as intermediary elements between the upper case and lower case. These positioning parts serve as mediators that provide secure connection through insertion holes without requiring visible external fastening members, thus resolving the contradiction between security and aesthetics.
2Reliability
If traditional screwing processes are used to fix the upper and lower cases, then the assembly is secure, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The patent removes the complex screwing process from the assembly method and replaces it with simple insertion of positioning parts into insertion holes. This extraction of the fastening function simplifies the assembly process while maintaining security through the positioning mechanism.
Solution Approach 2:
Instead of using external fasteners to pull or screw components together, the patent inverts the approach by using internal positioning parts that insert into holes to secure the assembly. This inversion simplifies the process from complex external fastening to simple internal insertion.
3Reliability
If multiple visible fastening members are used to secure the upper and lower cases, then the assembly is secure, but the number of parts increases and manufacturing efficiency decreases
Solution Approach 1:
The patent merges the fastening function into the positioning parts themselves, eliminating the need for separate visible fastening members. The positioning parts are integrated into the structure and secured through insertion holes, reducing the total number of parts and improving manufacturing efficiency while maintaining assembly security.
Solution Approach 2:
The positioning parts serve multiple functions: they provide structural support, ensure proper positioning, and secure the upper and lower cases simultaneously. This multi-functionality eliminates the need for multiple dedicated fastening members, improving productivity while maintaining reliability.

AI summary
A method for assembling a keyboard instrument includes installing a keyboard unit on a lower case such that an insertion hole of a key-connecting part of the keyboard unit is positioned corresponding to a lower side installation part of the lower case; thereafter, placing a upper case on the keyboard unit such that an upper side installation part of the upper case is positioned inside the insertion hole of the key-connecting part of the keyboard unit and mates with the lower side installation part of the lower case; and while the upper side installation part of the upper case is positioned inside the insertion hole of the key-connecting part of the keyboard unit and mates with the lower side installation part, inserting a fastening member into the upper side installation part and the lower side installation part to fix the upper case to the lower case via the fastening member.
