Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cistern flushing mechanisms face challenges in accurately regulating their height to match the cistern size, leading to potential involuntary adjustments and loss of regulation over time.
Innovation Solution
A device featuring a conduit with facing extensions and a tightening part that allows axial retention and release, utilizing projections and grooves to lock the long part at the correct height, ensuring precise regulation and prevention of involuntary changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple height regulation mechanism is used, then the device complexity is reduced, but the reliability of maintaining the regulated height deteriorates due to involuntary adjustments
Solution Approach 1:
The mechanism is divided into distinct functional components: a regulation element for adjusting height, a locking element with male and female parts for securing the position, and a guide screw for axial guidance. This segmentation allows each component to perform its specific function efficiently while maintaining overall simplicity.
Solution Approach 2:
The guide screw acts as an intermediary element that provides axial guidance to the locking mechanism, ensuring that the regulation element moves only along the correct path during adjustment and preventing lateral displacement that could compromise the locking reliability.
2Reliability
If a locking mechanism is added to prevent involuntary turning, then the reliability of height regulation is improved, but the device complexity increases
Solution Approach 1:
The male and female locking parts are integrated into a unified coupling mechanism that combines the locking function with the guide screw assembly. This merging reduces the number of separate components and simplifies the overall structure while maintaining effective locking capability.
Solution Approach 2:
The locking mechanism is designed to automatically engage and disengage through the rotational movement of the regulation element. The male and female parts self-align and lock when the regulation element is turned to the desired position, eliminating the need for separate locking operations or additional actuators.
3Ease of operation
If the regulation element is made freely movable for easy adjustment, then the ease of operation is improved, but the stability of the regulated position deteriorates due to potential slipping
Solution Approach 1:
The mechanism transitions between two dynamic states: a freely movable state during adjustment when the locking elements are disengaged, and a locked state when the male and female parts engage to secure the position. This dynamic behavior allows the system to optimize for ease of operation during adjustment and for position stability during use.
Solution Approach 2:
The guide screw is pre-configured with axial guidance features that automatically align the regulation element during insertion and adjustment. This preliminary positioning action ensures that the locking elements engage correctly the first time, preventing slipping and maintaining stability without requiring additional alignment operations.

AI summary
The invention relates to a device for regulating the height of a cistern flushing mechanism to adapt it to the same comprising a long part (1), which is adjustable axially and fits into a conduit (2) which passes through the upper base (4a) of the main body (4) of the flushing mechanism (5) and finding itself associated with a part of a push mechanism (19) which, when activated, moves the main body (4) of the flushing mechanism (5) downwards. Said conduit (2) is defined by two facing extensions (3), in the form of a neck, which start from the upper base (4a) of the main body (4). A circular tightening part (8) is coupled around the two facing extensions (3). Furthermore, the facing extensions (3) have inner opposing portions which face opposite portions of the long part (1). The long part can be used to assume a locked position in which it is axially retained, and a release position.
