Solution Overview
Problem
Existing height-adjustable tables face inefficiencies in installing and removing control boxes due to the need for tools and insecure friction-based connections, leading to potential falling and damage.
Innovation Solution
A height-adjustable table design featuring a retaining clip system with a semicircular snap portion and buffer elements, allowing for secure clamping of the control box to the table plate without tools, enhancing stability and ease of installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a friction-based connection is used to attach the control box to the table plate, then the installation process is simple and tool-free, but the connection strength is insufficient and the control box may fall off
Solution Approach 1:
The connection system is divided into multiple components: a retaining plate fixed to the table plate, and retaining clips attached to the control box. These segmented components work together to provide both ease of installation and strong connection, resolving the contradiction between simple installation and strong fixation.
Solution Approach 2:
The retaining clips are nested between the retaining plate and the control box, creating a secure layered connection structure. The clips engage with grooves on the retaining plate while simultaneously attaching to the control box, providing robust fixation without requiring tools.
2Strength
If a screw-based fixed connection is used to attach the control box to the table plate, then the connection strength is sufficient, but the installation and removal process requires tools and has low efficiency
Solution Approach 1:
The retaining clips are designed to be self-attaching components that can be easily fixed to the control box without tools. The elastic structure allows the clips to snap into place on the retaining plate, enabling tool-free installation while maintaining strong connection.
Solution Approach 2:
The retaining clips incorporate elastic elements that provide dynamic adjustment and automatic engagement. This dynamic structure allows for quick attachment and detachment without requiring threaded fasteners, significantly improving installation efficiency while maintaining connection strength.
3Device complexity
If only friction is used to hold the control box between the table plate and support beams, then the structure is simple, but the reliability is low and the control box may fall off during use
Solution Approach 1:
The retaining plate is pre-fixed to the table plate, and the retaining clips are pre-attached to the control box before assembly. This preliminary preparation ensures that when the control box is installed, the connection is immediately secure and reliable, preventing any risk of falling during use.
Solution Approach 2:
The connection system combines rigid components (retaining plate, control box housing) with elastic components (retaining clips with spring elements). This composite structure provides both the simplicity of a straightforward design and the reliability of multi-mechanism fixation, preventing accidental detachment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a stable, tool-free installation process for the control box, reducing the risk of falling and damage, while extending the service life of components through reinforced structures and buffering.
Implementation Method 1

AI summary
The present application relates to a height-adjustable table including a table plate. a table leg is fixedly connected to a side surface of the table plate, two brackets are arranged oppositely on the side surface of the table plate, and a retaining plate is fixedly connected to opposite inner sides of the two brackets, respectively. A control box is provided between the retaining plates, a retaining clip is fixedly connected to a side of the control box away from the side surface, and the retaining clip is detachably connected to the retaining plate. The present application has the advantages that the control box can be installed under the table plate more stably and firmly, at the same time, the installation is convenient.
