Quick-Release Toilet Seat Hinge Assembly Without Bolt Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional toilet seat replacement is hindered by rusted, corroded, or deformed mounting bolts and nuts, making it difficult to remove and replace the seat without damaging the existing hardware.
Innovation Solution
A hinge assembly featuring a rotatable or slidable cover with internal ribs that engage with a fixing component, allowing for easy installation and quick release of the toilet seat without needing to loosen the mounting bolts or nuts, and preventing movement of the bolts by locking the cover in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional mounting bolts and nuts are used to affix the toilet seat, then the toilet seat can be securely fastened to the toilet bowl, but the mounting bolts rust or corrode in the moist environment making them hard to loosen or unfasten
Solution Approach 1:
The mounting system is divided into separate functional components: a hinge base that remains permanently attached to the toilet bowl, and a hinge cover that can be easily removed and reattached. This segmentation allows the permanent fastening function to be separated from the removable cover function, solving the contradiction between secure fastening and easy removal.
Solution Approach 2:
The hinge base is pre-installed and permanently fixed to the toilet bowl before the toilet seat is mounted. This preliminary action ensures that the mounting bolts are already in place and properly positioned, eliminating the need to loosen or remove them during toilet seat replacement, thus preventing rust and corrosion issues.
2Strength
If mounting bolts and nuts are used to secure the toilet seat, then the toilet seat is firmly attached to the toilet bowl, but the nuts can recess due to the passage of time making them practically inaccessible
Solution Approach 1:
The fastening system is segmented into a permanent hinge base and a removable hinge cover. The hinge base contains the mounting bolts and nuts that remain firmly attached to the toilet bowl, while the hinge cover provides easy access to these components when needed for installation or maintenance.
Solution Approach 2:
The hinge cover acts as an intermediary component that provides access to the mounting bolts and nuts. When the hinge cover is removed, the mounting components become accessible for installation or maintenance, eliminating the problem of inaccessible recessed nuts.
3Strength
If conventional mounting methods are used, then the toilet seat can be affixed to the toilet bowl, but replacement requires undoing mounting screws or bolts from the toilet bowl
Solution Approach 1:
The mounting system is divided into a permanent hinge base that remains on the toilet bowl and a removable hinge cover that attaches to the toilet seat. This allows the toilet seat to be replaced by simply removing and reattaching the hinge cover, eliminating the time-consuming process of undoing and redoing mounting screws or bolts.
Solution Approach 2:
The hinge base is pre-installed on the toilet bowl during initial installation. This preliminary action ensures that the mounting components are already in place, so subsequent toilet seat replacements only require removing and reattaching the hinge cover, significantly reducing replacement time.
4Stability of the object's composition
If a rotatable cover is used to prevent movement of mounting bolts, then the bolts are secured in place, but the cover mechanism becomes more complex
Solution Approach 1:
The hinge cover is designed to be rotatable, allowing it to be easily opened and closed by simple rotational motion. This dynamic design provides a simple, intuitive mechanism for securing and releasing the mounting bolts without requiring complex locking or fastening mechanisms.

AI summary
A device for affixing a toilet seat to a toilet bowl includes a fixing component having a through-hole and removably coupling to a fixing member, a hinge base receiving the fixing component, a hinge cover, the hinge cover being rotatable when covering a portion of the hinge base and having a locked position, and a rib on an internal surface of the hinge cover, the rib including an inward projection for engaging an indentation of the fixing component when the hinge cover is in a locked position. The hinge cover of another device can slide onto the hinge base into a locked position. The device can quickly install the toilet seat and provide quick release of the toilet seat.
