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

VSEngineering 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

Engineering Contradiction:
Improvekeyboard playing comfortVSAvoiddesk space
Core Design Contradiction:
Ease of operationVSArea of stationary object

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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

Engineering Contradiction:
Improvekeyboard placementVSAvoiddrawer support capacity
Core Design Contradiction:
Ease of operationVSStrength

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.

Inventive Principle:
Principle #3Local quality

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.

Inventive Principle:
Principle #40Composite materials

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

Engineering Contradiction:
Improvekeyboard stabilityVSAvoidsliding plate resistance to sagging
Core Design Contradiction:
Stability of the object's compositionVSStrength

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.

Inventive Principle:
Principle #3Local quality

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.

Inventive Principle:
Principle #1Segmentation
