Threaded Toilet Bolt Cover for Long Bolts and Easy Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional toilet bolt covers fail to securely seal and accommodate toilet bolts of varying lengths, are difficult to install and remove, and often require cutting the bolt, which is time-consuming and may not be suitable for future adjustments in toilet base thickness or flooring.
Innovation Solution
A toilet bolt cover comprising a base with a flat circular portion and descending member to prevent rotation, and a cap with internal threads to securely mate with the base, accommodating bolts of different lengths and providing a secure, easy-to-install and remove solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If conventional bolt caps are used, then the cap can cover the bolt, but the cap is not deep enough to fit over long bolts and requires cutting the bolt
Solution Approach 1:
The bolt cover is divided into two separate components: a base that remains attached to the toilet base and a cap that fits over the base. This segmentation allows the cap to be shallower while the base provides the necessary depth to accommodate long bolts, eliminating the need to cut the bolt.
Solution Approach 2:
The base includes a descending member that extends downward into the mounting hole in the toilet base, utilizing the vertical dimension to provide bolt accommodation depth without increasing the horizontal profile or requiring a deeper cap.
2Ease of operation
If bases with external threads are used, then the cap can be easily removed, but the base may rotate with the cap making removal difficult
Solution Approach 1:
The descending member has an asymmetric cross-section that matches a corresponding asymmetric feature in the mounting hole, creating a keyed connection that prevents rotational movement while allowing vertical insertion and removal.
3Shape
If the bolt is cut to fit the cap, then the cap fits properly, but the procedure is time-consuming and difficult
Solution Approach 1:
By separating the bolt cover into a base and cap, the system accommodates full-length bolts without modification. The base provides the necessary depth internally, eliminating the need to cut the bolt and significantly reducing installation time and difficulty.
4Device complexity
If conventional covers without a base are used, then the cap can be simple, but the cover does not form an effective seal around the bolt, nut, and washer
Solution Approach 1:
The separation into base and cap allows the base to remain on the bolt and provide a sealing surface around the bolt, nut, and washer, while the cap provides the cosmetic cover. This ensures both sealing effectiveness and structural simplicity.

AI summary
A toilet bolt cover hides the portion of a toilet bolt extending upwardly through a mounting hole in the toilet base along with a washer and a nut threaded upon the bolt. The cover includes a base and a cap. The base has a wall with external threads and the cap has internal threads. The base of the cover has a descending member that extends downwardly into the mounting hole in the toilet base to limit rotation of the base of the cover.
