Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric tables with elevating functions are cumbersome and costly to transport and assemble due to their large size and complex assembly requirements, which involve aligning and adjusting transmission shafts, necessitating multiple technicians and increasing labor and transportation costs.
Innovation Solution
An electric table stand design featuring a holder with detachable support legs and a transmission apparatus that includes a motor, transmission shafts, and a coupling with a flexible body, allowing for quick assembly and shared use of components, reducing spare parts costs and simplifying storage and transportation by enabling automatic alignment and assembly through a flexible body that pushes joints into place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the support legs and table stand are separated for transportation, then transportation costs and storage space are reduced, but assembly complexity increases requiring alignment and adjustment of transmission shafts
Solution Approach 1:
The electric table stand is divided into separable components: the holder assembly and the support leg assemblies can be transported separately and then quickly reconnected at the installation site, reducing transportation space requirements while maintaining functional integrity
Solution Approach 2:
The coupling mechanism with flexible body enables self-aligning connection between transmission shafts. The flexible body automatically compensates for position deviations and guides the shafts into proper alignment during assembly, eliminating the need for manual alignment and adjustment operations
2Loss of time
If a coupling with flexible body is used to connect transmission shafts, then assembly time is reduced through automatic alignment, but the structure becomes more complex
Solution Approach 1:
A flexible body (elastic element) is integrated into the coupling mechanism to provide automatic alignment during assembly. The flexible material allows for elastic deformation that guides the transmission shafts into proper position, reducing assembly time while the overall structure remains relatively simple
3Reliability
If multiple technicians are deployed for assembly, then assembly reliability is improved, but labor costs increase
Solution Approach 1:
The coupling mechanism with flexible body enables self-aligning connection between transmission shafts. The flexible body automatically compensates for position deviations and guides the shafts into proper alignment during assembly, eliminating the need for manual alignment and adjustment operations
Solution Approach 2:
The complex alignment and adjustment operations are extracted from the assembly process through the self-aligning coupling mechanism. This removes the need for skilled technicians to perform manual alignment, reducing labor requirements while maintaining assembly quality

Function Achieved in This Case
The solution reduces assembly time, lowers labor and transportation costs, and minimizes space requirements during storage and transport by allowing for easy alignment and connection of support legs, while also reducing noise and vibrations through uniform stress distribution and simplified assembly steps.
Implementation Method 1
