Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Swimming pools pose a safety risk due to varying depths, which existing movable floor systems do not adequately address for users of different ages and abilities, as they lack efficient mechanisms for adjusting depth and stability.
Innovation Solution
A mechanical system comprising a moveable surface, two structures with sliding and hinged elements, and a hydraulic force transfer mechanism that allows for axial and radial displacement, enabling the surface to be adjusted to different depths and inclines, ensuring safety and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a movable floor system is implemented to adjust swimming pool depth, then safety for users of different ages is improved, but device complexity increases
Solution Approach 1:
The system is divided into multiple independent structures (first structure with solid rod, second structure with solid rod) that can be disposed at different locations. Each structure independently supports the movable surface, allowing the complex function of depth adjustment to be distributed across multiple simpler components rather than requiring a single complex mechanism.
Solution Approach 2:
A connecting rod is introduced as an intermediary element that movably couples the first and second structures. This connecting rod transfers force between the structures and enables coordinated movement, simplifying the overall control mechanism while maintaining system stability and safety.
2Stability of the object's composition
If multiple structures are used to support the movable surface, then stability is improved, but device complexity increases
Solution Approach 1:
The support system is segmented into multiple independent structures spaced apart from each other, with each structure providing stable support through its solid rod. This segmentation distributes the load and improves overall stability while keeping each individual structure relatively simple.
Solution Approach 2:
Multiple structures are combined through the connecting rod that movably couples them together. This merging allows the structures to work in unison, providing enhanced stability while sharing the mechanical complexity through a common coupling mechanism.
3Device complexity
If a single force transfer mechanism is used to displace multiple structures, then device complexity is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The connecting rod acts as an intermediary that distributes the force from the single force transfer mechanism to multiple structures. This intermediary element provides mechanical advantage and distributes precision requirements across multiple connection points rather than requiring extreme precision at a single critical interface.
Solution Approach 2:
The connecting rod is designed with movable coupling that allows for dynamic adjustment and accommodation of manufacturing tolerances. The movable connection enables the system to self-adjust during operation, reducing the stringency of manufacturing precision requirements while maintaining effective force transfer.
