Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual extension mechanisms are used, then device complexity is reduced, but ease of operation deteriorates due to difficulty in extending and retracting
Solution Approach 1:
The patent replaces manual mechanical extension mechanisms with an electric motor assembly that automatically extends and retracts the tabletop. The motor assembly includes a motor, drive shaft, and transmission mechanism that converts rotational motion into linear motion for extending the tabletop sections, eliminating the need for manual cranks or levers.
Solution Approach 2:
The extension mechanism is designed to operate autonomously through the motor assembly, which self-regulates the extension and retraction process. The system includes sensors and control circuitry that detect the extended position and automatically stop the motor, eliminating the need for continuous manual intervention.
2Ease of operation
If remote control operation is added, then ease of operation is improved, but device complexity and cost increase
Solution Approach 1:
The patent introduces a remote control device as an intermediary between the user and the motor assembly. The remote control contains a transmitter that sends wireless signals to a receiver connected to the motor assembly, allowing the user to operate the extension mechanism from a distance without adding complex wired controls to the table structure.
Solution Approach 2:
The patent replaces physical control mechanisms (buttons, switches, or levers on the table) with wireless electronic control through the remote device. This substitution uses radio frequency or infrared communication to transmit control signals, simplifying the physical structure while maintaining full control functionality.
3Volume of moving object
If extension assemblies are fully integrated, then volumetric efficiency is improved, but ease of manufacture deteriorates due to assembly complexity
Solution Approach 1:
The patent divides the tabletop into separate extendable sections that can be manufactured independently and then assembled. The extension assemblies include discrete components such as individual tabletop sections, hinge mechanisms, and support structures that can be produced separately and connected through standardized joining methods.
Solution Approach 2:
The extension assemblies are designed to nest within each other when retracted, with smaller components fitting inside larger ones. The tabletop sections fold or slide into compact configurations that minimize the overall volume occupied during storage, while the modular design allows for straightforward assembly by simply connecting the nested components.

AI summary
A motorized extendable table having a tabletop assembly, first and second extension assemblies, a frame assembly, first and second extension frame assemblies, a motor housing, a computer assembly, a motor assembly, and a base assembly. In operation, the motor assembly moves the extension frame assemblies from a retracted to an extended configuration. Before reaching a fully extended configuration, the extension assemblies are raised to a same plane as that of the tabletop assembly. To go from the extended to the retracted configuration, the motor assembly moves the system in an opposite direction, moving the extension frame assemblies down and back onto a lower plane. Extension frame assemblies continue moving back until the fully retracted configuration is reached.
