Supporting frame for a steel bath
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support frames for steel bathtubs are unstable and complicated to adjust, with numerous pivoting joints that limit stability and complicate alignment.
Innovation Solution
A support frame with positionally variable support plates and carriages that allow easy alignment and secure attachment to a steel bathtub via non-positive and/or positive and/or material-to-material attachment, utilizing locking rails, cams, and adhesive layers for stable connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If numerous pivoting joints are used in the support frame, then the frame can accommodate various bathtub shapes, but the stability of the frame is reduced
Solution Approach 1:
The support frame is divided into modular components: a stable base frame structure and separate adjustable support arms that can be independently positioned. This segmentation allows the frame to adapt to different bathtub shapes while maintaining overall structural stability through the rigid base frame.
Solution Approach 2:
The support frame incorporates adjustable and movable components such as height-adjustable legs and pivotable support arms that can be dynamically repositioned to accommodate various bathtub configurations. These dynamic elements allow adaptation without compromising the static stability of the main frame structure.
2Adaptability or versatility
If numerous pivoting joints are used in the support frame, then the frame can accommodate various bathtub shapes, but the complexity of adjusting the frame is increased
Solution Approach 1:
The adjustment mechanism is segmented into simple, independent components such as individual height-adjustable legs and separate pivot points, each with its own simple adjustment mechanism. This reduces the overall complexity compared to a fully interconnected pivoting system.
Solution Approach 2:
Instead of using a complex mechanism to achieve adjustment, the design uses simple, straightforward adjustment methods such as threaded rods, pins, and basic hinges that are easy to manipulate, inverting the approach of using complex mechanical linkages for adjustment.
3Ease of operation
If the holding jaws are made movable on the rail, then the alignment of the support frame is simplified, but the risk of accidental adjustment increases
Solution Approach 1:
The holding jaws are pre-positioned on the rail at appropriate locations before installation. During installation, they can be easily slid to the correct position, and then locked in place using simple locking mechanisms such as set screws or clip locks that prevent accidental movement while maintaining ease of initial positioning.
Solution Approach 2:
A locking mechanism acts as an intermediary between the movable holding jaw and the rail, allowing easy movement during installation but preventing accidental adjustment during use. The locking mechanism can be easily engaged and disengaged by the installer but remains secure during normal operation.
