Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collapsible power-driven table stands are inefficient in terms of assembly, length-adjustment, and collapsing mechanisms, often requiring numerous parts and manual steps, which can lead to wiring visibility and interference risks and inefficient operation.
Innovation Solution
A collapsible power-driven table stand design featuring a supporting body with an elongated main support structure comprising a central beam and lateral beams, guide means for length adjustment, and a limiter arrangement to prevent excessive displacement, along with a simplified anchoring system using fewer components, concealing wiring and allowing easy extension and collapse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If numerous screws and separate components are used to anchor sidewing brackets and stands to rectangular columns, then the structural strength and stability are improved, but the device complexity and assembly time increase significantly
Solution Approach 1:
The patent integrates the sidewing brackets and rectangular columns into a unified supporting body structure where the brackets are formed as integral parts of the columns rather than separate components requiring multiple screws for attachment. This merging reduces the number of fastening elements while maintaining structural integrity through the unified design.
Solution Approach 2:
The supporting body structure serves multiple functions simultaneously: it provides structural support, houses the controller, contains wiring channels, and enables pivotal attachment of stands. This multi-functionality eliminates the need for separate dedicated components for each function, reducing overall device complexity while maintaining strength.
2Stability of the object's composition
If numerous screws and separate components are used to anchor sidewing brackets and stands to rectangular columns, then the structural stability is improved, but the assembly time and manual steps increase significantly
Solution Approach 1:
By merging the sidewing brackets and rectangular columns into an integral supporting body structure, the patent eliminates multiple separate assembly steps involving individual screw fastenings. The unified structure reduces assembly operations to simpler attachment processes while maintaining structural stability through the integrated design.
3Reliability
If wirings are routed between the controller and driving units in the receiving slot, then the electrical connections are established, but the wirings become visible and susceptible to interference from user bodyparts or foreign objects
Solution Approach 1:
The patent extracts the wirings from the exposed receiving slot area and routes them through dedicated wiring channels that are concealed within the supporting body structure. This separation removes the harmful factor of wiring exposure while maintaining the electrical connections between the controller and driving units.
4Ease of repair
If the design uses separate screws for anchoring sidewing brackets and stands to rectangular columns, then the ease of repair is improved, but the device complexity and base material amount increase
Solution Approach 1:
The supporting body structure is designed as a universal component that integrates multiple functions: structural support, controller housing, wiring routing, and stand attachment. This consolidation reduces device complexity while maintaining repairability through modular attachment points designed for straightforward replacement of individual components.

AI summary
A collapsible power-driven table stand (1) has a supporting body (10) having an elongated main support structure (11) extending in a longitudinal direction (L), and first and second stands (20, 20') comprising first and second driving units (21, 21') and one or more first and second telescopic leg sections (22, 22'), respectively, driven by the first and second driving units (21, 21') to move axially relative to each other. The first and second stands (20, 20') are pivotally attached to the supporting body (10) at or near its respective ends in order to allow the first and second stands (20, 20') to extend or collapse relative to the supporting body (10). The elongated main support structure (11) comprises an elongated central beam (40) formed by a bottom surface (41) and first and second side walls (42, 42') extending perpendicularly from the bottom surface, the central beam having a generally U-shaped cross-section. It also comprises elongated first and second lateral beams (30, 30') formed by respective first and second side walls (32, 33, 32', 33') and bottom surfaces (31, 31') extending perpendicularly between the first and second side walls along proximal portions (34, 34') of the first and second lateral beams, respectively. The first and second lateral beams have a generally U- shaped cross-section at the proximal portions. A respective proximal end (36, 36') of the proximal portions (34, 34') of the first and second lateral beams (30, 30') is open for slidably receiving the central beam (40) from a first end (41a) thereof, whereas respective distal portions (35, 35') of the first and second lateral beams (30, 30') are connected to the first stand and second stands (20, 20'). Guide means (50; 60) are provided for guiding the central beam (40) to be slidably supported on the bottom surfaces (31, 31') of the first and second lateral beams (30, 30'). The supporting body (10) is length-adjustable in the longitudinal direction (L) by displacing the first lateral beam (30) and/or second lateral beam (30') with respect to the central beam (40) in the longitudinal direction.
