Sliding Keyboard Desk Structure to Prevent Tray Sagging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional desks are not ergonomically suited for music experts, as they do not accommodate electronic keyboards and computer monitors effectively, leading to wrist strain and insufficient space, and existing computer desks have limited keyboard drawer width and low support capacity, causing damage.
Innovation Solution
A desk with a sliding plate that adjusts in height, supported by guide rails and a center reinforcing rail to prevent sagging, allowing for optimal placement of keyboards and monitors, and featuring adjustable support frames and shock-absorbing pads for stability and vibration absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a keyboard is placed on a conventional desk, then the desk can be used for general purposes, but the keyboard occupies large area and the height is not suitable for playing
Solution Approach 1:
The desk is segmented into multiple functional zones: a main desk surface for general use and a separate pull-out keyboard tray for music work. This segmentation allows the keyboard to be placed in a dedicated space with appropriate height and angle, while the main desk surface remains available for other purposes, thus resolving the conflict between keyboard playing comfort and desk space utilization.
Solution Approach 2:
The keyboard tray is designed to slide out horizontally from the desk, creating an additional dimensional space for keyboard placement. This allows the keyboard to be positioned at an ergonomically suitable height and angle without permanently occupying valuable vertical desk space, effectively adding a new spatial dimension for music work.
2Ease of operation
If a keyboard drawer is added to a computer desk, then keyboard placement is improved, but the drawer is limited in width and has low support capacity
Solution Approach 1:
The keyboard tray is designed with non-uniform thickness, being thicker at the center portion and thinner at the edges. This local quality variation provides enhanced structural strength and support capacity at the center where the keyboard weight is concentrated, while maintaining a sleek appearance at the edges. The reinforced center portion effectively prevents sagging and damage under keyboard weight.
Solution Approach 2:
The keyboard tray is constructed using composite material structure, combining materials with different properties to achieve both strength and weight reduction. This composite construction allows the tray to have high support capacity to bear keyboard weight while maintaining a lightweight design that does not burden the desk structure.
3Stability of the object's composition
If the sliding plate is made wide to support keyboard, then keyboard stability is improved, but the sliding plate sags under load
Solution Approach 1:
The sliding plate is designed with variable thickness, being thicker at the center portion and thinner at the edges. This local reinforcement at the center provides the necessary strength to prevent sagging under keyboard load, while the thinner edges reduce overall weight and material usage. This non-uniform thickness distribution optimizes both stability and strength.
Solution Approach 2:
The sliding plate is divided into multiple sections with different thicknesses and structural characteristics. The center portion is segmented as a reinforced zone with greater thickness for load bearing, while the peripheral zones are thinner. This segmentation allows the plate to achieve both wide surface area for keyboard stability and sufficient structural strength to resist sagging.
