Bath Seat with Extendable Stabilizing Arms to Prevent Tipping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bath seats for young children and babies often fail to meet stricter safety standards due to tipping hazards, leading to recalls and the need for improved stability and leg opening security during bathing.
Innovation Solution
A bath seat with a base, seat top, and circumferentially disposed support members, featuring independently extendable and retractable rigid stabilizing arms with suction cups that can rotate for secure attachment to the bathtub, ensuring stability and safety by preventing tipping and allowing for adjustable fit within various tub widths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional suction cupped bath seats are used, then they provide basic seating functionality, but they tip over easily and fail to meet stricter safety standards
Solution Approach 1:
The patent employs dynamic arms that can extend and retract, allowing the bath seat to adapt its stability configuration. The arms extend to engage with the tub walls, providing active stabilization against tipping forces, and can retract when not needed, optimizing the balance between stability and safety.
Solution Approach 2:
The patent changes the physical state and configuration parameters of the stabilizing arms, transitioning them between extended and retracted positions. This parameter change allows the system to actively respond to stability requirements while maintaining safety standards, transforming a static structure into a dynamically adjustable one.
2Reliability
If rigid stabilizing arms with suction cups are added, then stability and safety are improved, but device complexity increases
Solution Approach 1:
The patent divides the stabilizing function into separate modular arms, each with its own suction cup mechanism. This segmentation allows each component to be optimized independently and simplifies the overall structure by distributing the stabilization function across multiple simple, identical units rather than one complex system.
Solution Approach 2:
The suction cups on the stabilizing arms automatically engage with the tub walls through vacuum adhesion without requiring manual operation or complex control mechanisms. The arms self-adjust to provide stability, eliminating the need for additional actuators or control systems and reducing overall device complexity.
3Reliability
If the bath seat structure is made more stable, then tipping is prevented, but ease of installation and removal may be affected
Solution Approach 1:
The dynamic arms transition between extended and retracted states, allowing the bath seat to be easily installed and removed when retracted, while providing stability when extended. This dynamic configuration resolves the contradiction by making the stabilizing feature optional and controllable.
Solution Approach 2:
The arms are pre-configured in a retracted position for easy installation, and can be extended after installation to provide stability. This preliminary configuration allows users to first install the seat without obstruction, then activate the stabilizing feature as needed.

Function Achieved in This Case
The solution provides enhanced stability and safety by preventing the bath seat from tipping and ensuring secure attachment to the tub, meeting stricter safety standards and reducing the risk of drowning hazards, while allowing for easy installation and removal.
Implementation Method 1
Each arm has a suction cup at or near one end thereof engageable by means of suction with a wall of the bathtub
