Solution Overview
Problem
Conventional electric height-adjustable desks suffer from cumbersome and inefficient manual assembly due to the use of screws for connecting components like columns, frames, and side boards.
Innovation Solution
An electric height-adjustable desk design featuring a detachable latch mechanism, snap-fitted engaging grooves and journals, and a locking device that allows for quick assembly by snap-fitting and locking components without screws, enhancing stability and aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If screws are used to connect the column, frame, and side board, then the connection strength is sufficient, but the assembly process becomes cumbersome and inefficient
Solution Approach 1:
The patent extracts and eliminates the screw connection method from the assembly process, replacing it with a latch mechanism that enables tool-free assembly. The latch mechanism comprises a latch arm that can be manually operated to engage and disengage the connection between the side board and crossbar, completely removing the need for screws and significantly improving assembly efficiency and convenience.
Solution Approach 2:
The latch mechanism is designed to be self-operating without requiring external tools or complex procedures. The latch arm can be manually engaged by simply pressing it against the latch block, and the connection is maintained through the elastic force of the spring that keeps the latch arm in the engaged position. This self-service mechanism eliminates the need for screwdrivers or other assembly tools, making the assembly process trivial and highly efficient.
2Productivity
If a latch mechanism is used instead of screws, then assembly efficiency is improved, but the connection stability may be compromised
Solution Approach 1:
The latch block is designed with a curved surface that matches the curvature of the latch arm's engagement surface. This curved geometry ensures that the latch arm engages deeply and securely with the latch block, distributing the connection forces evenly and preventing accidental disengagement. The curved design also allows for smooth engagement and disengagement motions, maintaining both stability and ease of operation.
Solution Approach 2:
The patent incorporates a spring element that provides elastic force to maintain the latch arm in the engaged position with sufficient pressure. This pre-applied elastic force acts as a cushioning mechanism that compensates for any gaps or misalignments between the latch arm and latch block, ensuring stable and reliable connection without requiring overly tight tolerances or complex adjustment procedures.
3Reliability
If multiple connection points are provided for the latch mechanism, then the connection reliability is enhanced, but the device complexity increases
Solution Approach 1:
The connection system is segmented into distinct functional elements: the latch arm, latch block, spring element, and positioning features. Each element performs a specific function, and their simple geometric shapes and straightforward arrangements minimize manufacturing complexity. The segmentation allows for easy assembly and disassembly while providing multiple connection points through the distributed latch blocks along the crossbar, enhancing reliability without significantly increasing overall device complexity.
