Motorized Adjustable Height Table with Tool-Free Lug-and-Slot Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current motorized tables require complex assembly and connection to a power source, which can create trip hazards and limit their placement due to the need for tools and fixed power connections.
Innovation Solution
An adjustable height table design featuring telescoping legs with integrated motors and a modular frame that allows for quick assembly and secure attachment to the table top using lugs and slots, along with a built-in power supply and control panel for easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional fasteners and tools are used to assemble table legs, then secure attachment is achieved, but assembly time and complexity increase
Solution Approach 1:
The table leg assembly is segmented into modular components: a leg portion, a motorized height adjustment mechanism, and an attachment interface with lugs. This segmentation allows for tool-free snap-fit assembly while maintaining secure attachment, directly resolving the contradiction between assembly ease and secure attachment.
Solution Approach 2:
Traditional mechanical fasteners (screws, bolts, tools) are replaced with a snap-fit mechanical system using lugs that engage with slots in the frame. This substitution eliminates the need for tools and complex assembly procedures while maintaining secure attachment, addressing both assembly ease and time reduction.
2Ease of operation
If external power connections are used, then motorized height adjustment is enabled, but trip hazards and placement limitations occur
Solution Approach 1:
The power supply is merged with the table structure by integrating a rechargeable battery into the frame. This combines the motorized height adjustment functionality with a self-contained power source, eliminating external power connections and associated trip hazards while maintaining ease of operation.
Solution Approach 2:
A rechargeable battery serves as an intermediary energy storage device between the external world and the motorized mechanisms. This intermediary allows the table to operate autonomously without direct connection to external power sources, removing trip hazards from power cables while preserving height adjustment capability.
3Ease of operation
If external power connections are required, then motorized functionality is provided, but placement flexibility is reduced
Solution Approach 1:
The power supply system is merged into the table structure through integration of a rechargeable battery in the frame. This self-contained power system enables motorized height control while providing complete placement flexibility, as the table can be positioned anywhere without access to external outlets.
Solution Approach 2:
The power system transitions from a static external connection requirement to a dynamic self-contained battery system. This dynamic approach allows the table to adapt to any placement location while maintaining motorized functionality, enhancing both ease of operation and placement flexibility.
4Strength
If complex assembly procedures are used, then secure structural integrity is achieved, but assembly complexity increases
Solution Approach 1:
The table structure is segmented into modular components with standardized attachment interfaces. The leg portions, motorized mechanisms, and frame are designed as separate modules that connect through simple lug-and-slot interfaces, reducing assembly complexity while maintaining structural integrity through precise geometric fitting.
Solution Approach 2:
Complex mechanical fastening systems are replaced with simplified snap-fit connections using lugs that engage with slots. This substitution maintains structural integrity through proper geometric design and material selection while dramatically reducing assembly complexity and eliminating tool requirements.

AI summary
A table includes a table top having a frame attached to a lower surface of the table top. The table also includes a first leg having lugs and a second leg having lugs. The lugs of the first leg and the second leg are received in slots of the frame to attach the legs to the table. The legs are telescopically movable to adjust the height of the table top.
