Quick release structure for toilet lid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing quick release structures for toilet lids are complex and lack protection, leading to potential safety hazards due to accidental detachment during use.
Innovation Solution
A quick release structure comprising a movement cover, linkage shaft, rotating shaft, slide switch, and protective cover, which allows for simple operation and prevents mistaken touch by exposing or shielding the slide switch based on its state, ensuring safe mounting and dismounting of the toilet lid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a quick release structure is used to enable quick disassembly of the toilet lid, then the ease of operation is improved, but the reliability deteriorates due to accidental detachment from mistaken touch
Solution Approach 1:
The quick release structure is divided into separate functional components: a button for initiating release, a triggering mechanism for detecting button pressure, and a locking mechanism for maintaining connection. This segmentation allows independent optimization of each component - the button provides easy operation while the locking mechanism ensures reliability against accidental detachment.
Solution Approach 2:
A triggering mechanism acts as an intermediary between the button and the locking mechanism. This intermediary requires deliberate activation through the button to transition the locking mechanism from locked to unlocked state, preventing direct or accidental disconnection while maintaining quick release capability when properly activated.
2Device complexity
If the quick release structure is simplified for easy operation, then the device complexity is reduced, but the reliability worsens due to lack of protection against mistaken touch
Solution Approach 1:
The button, triggering mechanism, and locking mechanism are integrated into a single compact assembly where components work together in sequence. This merging maintains simplicity by eliminating separate control systems while incorporating multiple functions (activation, detection, locking) into one unified structure that prevents mistaken touch.
Solution Approach 2:
The triggering mechanism automatically detects button pressure and activates the locking mechanism transition without requiring additional user actions or complex control systems. The structure serves itself by using the mechanical energy from button pressing to trigger the release sequence, maintaining simplicity while ensuring reliable protection against accidental detachment.

AI summary
The utility model provides a quick release structure for a toilet lid, including: a movement cover, a linkage shaft, a slide switch, a rotating shaft and a protective cover, wherein the movement cover defines an insertion hole and an avoidance slot; the linkage shaft is provided with a clamping slot, and the linkage shaft is adapted to be inserted into the insertion hole; the rotating shaft is provided with a connection portion, the connection portion is adapted to be clamped into the clamping slot through the avoidance slot, and the rotating shaft can drive the linkage shaft to synchronously rotate when the connection portion is clamped into the clamping slot; the slide switch is slidably mounted in the avoidance slot to expose the clamping slot or cover the clamping slot; and the protective cover can expose the slide switch or shield the slide switch.
