Electric height-adjustable desk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric height-adjustable desks have complex assembly processes, occupy valuable space under the desk, and provide poor user experiences due to protruding components and inadequate control interfaces.
Innovation Solution
The design features an integrated desk board body with a lifting assembly and base, hidden cross beam and transmission rod, a drawer for storage, and a manual controller interface positioned to avoid accidental activation, along with an LED light strip for enhanced user feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the cross beam and transmission rod are disposed in a downward protrusion manner at the bottom of the desk board frame, then the structural connection between lifting columns is improved, but the space under the desk board is reduced and users may touch these components inadvertently
Solution Approach 1:
The cross beam and transmission rod are nested within the desk board frame structure. The cross beam is positioned inside the frame's hollow section, and the transmission rod is housed within a dedicated groove in the frame, eliminating downward protrusion while maintaining structural connectivity between lifting columns.
Solution Approach 2:
The design transitions from a downward vertical arrangement to a horizontal integration within the frame plane. The cross beam extends horizontally between lifting columns inside the frame, and the transmission rod runs horizontally within a groove, moving components from a protruding dimension to an integrated plane.
2Ease of operation
If the manual controller is mounted at the bottom of the desk board close to the user, then controlling the ascent and descent is facilitated, but the controller protrudes downwardly occupying space and can be easily touched by the user leading to inconvenience
Solution Approach 1:
The manual controller is relocated from the bottom surface of the desk board to the side surface, specifically on the front side wall close to the user. This dimensional relocation maintains operational accessibility while eliminating the protrusion issue and accidental touch problems associated with bottom-mounted controllers.
Solution Approach 2:
The controller is positioned on a specific localized area of the side wall (front side wall close to the user) rather than distributed or centrally mounted. This localized positioning optimizes both accessibility for the user and avoidance of accidental activation, creating a dedicated control zone.
3Area of stationary object
If the manual controller is embedded into the desk board, then the space under the desk board is increased, but a groove must be opened on the desk board having high requirements for mounting accuracy and processes
Solution Approach 1:
Instead of embedding the controller into the desk board (requiring grooves and high precision), the controller is mounted on the side surface of the desk board frame. This dimensional change eliminates the need for precision groove machining while maintaining space efficiency and avoiding complex manufacturing requirements.
4Adaptability or versatility
If the two lifting columns are separated and need to be assembled by the user after purchase, then the drive motor can correspond to each lifting column independently, but the assembly efficiency is affected and the process is complicated
Solution Approach 1:
The drive motor, transmission rod, and two lifting columns are merged into a single integrated lifting assembly. This unified structure eliminates the need for users to separately assemble multiple components, significantly improving assembly efficiency while maintaining the functional correspondence between the motor and each lifting column through the integrated transmission mechanism.
