Top Mount Self-Locking Mechanism for Smart Toilet Seat Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of electronic functions in smart toilet top mounts leads to an unstable gravity center when the seat ring is lifted, affecting user comfort due to potential accidental overturning.
Innovation Solution
A top mount self-locking mechanism comprising an outer cylinder, a limiting clamp spring, a rotating shaft, and a positioning sleeve, where the limiting clamp spring with convex ribs and shifting pieces maintains the seat ring's position, preventing accidental overturning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple electronic functions are integrated into the smart top mount, then the functionality and user experience are improved, but the structure of the rear base becomes bigger and the gravity center becomes unstable
Solution Approach 1:
The spring-loaded limiting clamp mechanism acts as a counterweight system that provides upward force to balance the downward gravitational force on the seat ring. The spring force compensates for the unstable gravity center caused by the enlarged rear base structure, maintaining stability during the lifted position.
Solution Approach 2:
The self-locking mechanism is pre-configured with the spring-loaded limiting clamp and convex rib positioning system before use. When the seat ring is lifted, the mechanism automatically engages the convex rib with the limiting clamp at predetermined positions, preventing accidental overturning before it can occur.
2Ease of operation
If the seat ring is made to be freely movable for cleaning purposes, then the ease of operation is improved, but the risk of accidental overturning increases
Solution Approach 1:
The mechanism transitions from a static locked position to a dynamic movable state and back to locked position. The spring-loaded limiting clamp allows the seat ring to be moved when force is applied (for cleaning), but automatically returns to and locks in the stable lifted position when the force is removed, providing both mobility and stability.
Solution Approach 2:
The positioning sleeve acts as an intermediary component between the seat ring and the limiting clamp mechanism. It guides the movement of the convex rib and ensures proper engagement with the limiting clamp, facilitating controlled movement while maintaining position stability.
3Reliability
If a self-locking mechanism is added to prevent accidental overturning, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The limiting clamp, spring, and positioning features are merged into a compact integrated assembly within the outer cylinder. The convex ribs on the positioning sleeve and corresponding limiting clamps work together as a unified self-locking system, reducing the need for separate complex components while achieving reliable position stability.
