Solution Overview
Problem
Existing toilet sets with foldable parts often result in collisions during folding, leading to visible marks, damage, and unpleasant noise, particularly when the foldable lid or seat contacts the wall or shower facility, which affects the appearance and quality perception.
Innovation Solution
Incorporating a rotary stop positioned around the axis of rotation, combined with a sleeve-like configuration and a snap-over mechanism, to prevent unwanted collisions by limiting the folding movement and distributing forces, while being easy to clean and conceal from view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the foldable part is allowed to fold up freely without limitation, then the folding movement is unrestricted and easy to operate, but collisions occur between the foldable part and the wall or shower facility, causing visible marks, damage, and unpleasant noise
Solution Approach 1:
The rotary stop is positioned to limit the folding movement before the foldable part can collide with the wall or shower facility. By establishing the position limit in advance, the harmful collision is prevented before it occurs, while still allowing full operational freedom within the safe range.
Solution Approach 2:
The rotary stop acts as an intermediary mechanism between the foldable part and the wall/shower facility. Instead of allowing direct contact that causes damage and noise, the rotary stop mediates the movement by providing a controlled stopping point, thus protecting the foldable part and surrounding structures.
2Object-affected harmful factors
If a rotary stop is introduced to limit folding movement and prevent collisions, then collision damage and noise are reduced, but the device complexity increases
Solution Approach 1:
The rotary stop is integrated with the existing rotary joint structure of the foldable part. By merging the stop function with the rotational mechanism already present in the toilet set, the design avoids adding separate complex components while still achieving effective movement limitation and collision prevention.
Solution Approach 2:
The rotary stop serves multiple functions: it limits the folding movement range, prevents collision with the wall or shower facility, reduces noise, and protects the foldable part from damage. This multi-functionality allows a single component to address several concerns without proportionally increasing device complexity.
3Object-affected harmful factors
If the rotary stop is positioned to effectively prevent collisions, then protection against damage is improved, but the cleaning accessibility and visibility may be affected
Solution Approach 1:
The rotary stop is nested within or integrated into the existing structural components of the foldable part assembly. This nesting allows the stop mechanism to be concealed within the structure, providing effective collision protection while maintaining a clean external appearance and not interfering with cleaning accessibility of the visible surfaces.

Function Achieved in This Case
The rotary stop effectively prevents collisions, reducing visual defects and damage, while the snap-over mechanism ensures safety and durability, enhancing the overall quality and usability of the toilet set.
