Keyboard Fixing Structure With Isolated Impact Reinforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic keyboard instruments face issues with the strength of the fixing portion being compromised when subjected to external impacts, leading to potential damage due to the transmission of force through ribs.
Innovation Solution
A frame-shaped support member supports an internal member, with a fixing member inside the frame that is reinforced by a reinforcement member not connected to the support member, thereby distributing and reducing the impact load on the fixing member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If ribs are provided on the outer peripheral portion of the fixing portion to improve strength, then the strength of the fixing portion is improved, but the fixing portion becomes vulnerable to impact damage from external loads
Solution Approach 1:
The fixing portion is segmented into multiple functional elements: the boss-shaped fixing portion for mounting, ribs for strength enhancement, and a reinforcement member for impact protection. This segmentation allows each element to perform its specific function independently, resolving the contradiction between needing strength and avoiding impact damage transmission.
Solution Approach 2:
The reinforcement member acts as an intermediary element between the fixing portion and the internal member. It intercepts and distributes impact loads before they can be transmitted to the fixing portion, thereby protecting the fixing portion from impact damage while maintaining its strength-enhancing ribs.
2Stability of the object's composition
If the reinforcement member is connected to both the fixing member and the support member, then structural stability is improved, but complexity of the device increases
Solution Approach 1:
The reinforcement member is extracted from the support member structure and positioned independently within the frame. This extraction simplifies the overall structure by eliminating the need for the reinforcement member to be connected to the support member, while still achieving the desired structural stability through its connection to the fixing member alone.

AI summary
A device includes: a frame-shaped support member that is configured to support an internal member; a fixing member that is inside a frame of the support member and is configured to fix the internal member; and a reinforcement member that is connected to the fixing member and with which the fixing member is reinforced. The reinforcement member is not connected to the support member.
