Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foldable ironing tables are inconvenient to use and store due to the need for manual adjustment of pin-joined legs, which can result in finger pinching and inefficient space utilization.
Innovation Solution
A multifunctional folding table design featuring parallel rails, a hydraulic telescoping rod, and a locking mechanism that allows for easy height adjustment and secure locking, enabling convenient unfolding and folding with improved safety and space efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a pin-joined leg structure is used to support the board, then the table can be folded for storage, but the user may get finger pinched during adjustment and the operation becomes inconvenient
Solution Approach 1:
The patent replaces the manual pin-joining mechanism with a hydraulic telescoping rod system. The hydraulic rod automatically extends and locks into position to support the board, eliminating the need for manual pin insertion and extraction. This substitution of mechanical systems resolves the finger pinching hazard while maintaining foldable capability.
Solution Approach 2:
The hydraulic telescoping rod system operates automatically without requiring user intervention for pin insertion. The leg frame with hydraulic rod self-extends to support the board when needed, and the locking mechanism automatically secures the position. This self-service mechanism eliminates the inconvenient manual adjustment process.
2Reliability
If a tight coupling between pin-joined leg and slot is used to reliably support the board, then the board is securely supported, but significant effort is required to plug the leg into the slot
Solution Approach 1:
The patent replaces the tight mechanical coupling of pin-and-slot with a hydraulic telescoping rod system. The hydraulic mechanism provides reliable support through fluid pressure and automatic locking, eliminating the need for forceful pin insertion. This substitution reduces the force required while maintaining support reliability.
Solution Approach 2:
The patent employs a hydraulic telescoping rod to provide the support function. The hydraulic system uses fluid pressure to extend and lock the leg frame, providing reliable board support without requiring manual force to insert pins into slots. This hydraulic mechanism resolves the contradiction between support reliability and adjustment effort.
3Strength
If the table is designed as a floor-standing ironing table with long stand, then the board can be properly supported for ironing, but the table becomes heavier and more difficult to maneuver
Solution Approach 1:
The patent transforms the static, heavy floor-standing table into a dynamic, wall-mounted folding table. The leg frame with hydraulic telescoping rod can be extended when needed for ironing and folded against the wall when not in use. This dynamic design maintains board support capability while dramatically reducing the weight that must be maneuvered, as the table is mounted to the wall structure.
Solution Approach 2:
The patent transitions from a floor-standing three-dimensional structure to a wall-mounted system that utilizes the vertical wall surface for storage. The leg frame folds parallel to the wall when not in use, effectively removing the horizontal footprint and reducing the perceived weight burden on the user. This dimensional change from floor-based to wall-based mounting resolves the weight and maneuverability issue.
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 enhances user safety by eliminating finger pinching and improves space utilization by allowing for easy and secure adjustment and storage of the table, making it more practical for tight spaces.
Implementation Method 1
a hydraulic telescoping rod has a second end hinged to the second positioning element
Implementation Method 2
a leg frame having a back edge hinged to a back end of the board member
Implementation Method 3
The locking member provides a notch for locking the sliding pole

AI summary
The multifunctional folding table includes a board member, a first support member, and a locking member. The board member is hinged with first support member. The first support member is joined to a wall surface. When the multifunctional folding table is unfolded, the board member is perpendicular to the first support member. A leg frame hinged to an end of the board member adjacent to the first support member rests against the floor. The locking member is disposed to a bottom side of the board member to reliably maintain and lock the board member's unfolded state.
