Dual Flush Handle Converter Assembly Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dual flush toilet systems often require significant effort to replace or modify the activation device, which may not be preferred by customers, and there is a need for a method to convert the handle of the activation device without substantial modification.
Innovation Solution
The development of a handle converter assembly that allows for the conversion of the activation device by detachably connecting a handle assembly to an actuation control box, using a transfer box and a mounting extension, to translate rotational motion into linear motion, enabling the selection between quick flush and full flush modes without replacing the entire system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the entire dual flush toilet system is replaced or modified to change the activation device, then the activation device can be changed to a preferred type, but significant effort and system replacement is required
Solution Approach 1:
The activation device is segmented into separate components: a handle assembly and an actuation control box. The handle assembly can be detached and replaced independently without modifying the actuation control box or the rest of the toilet system, thus reducing modification effort while changing activation device usability
Solution Approach 2:
The actuation control box is designed with a universal interface that can accept different handle assemblies. The mounting extension with standardized cable anchor and handle mounting features allows the same actuation control box to work with multiple handle types, enabling easy conversion between activation device preferences
2Ease of manufacture
If a handle converter assembly is used to convert the activation device, then system replacement is avoided, but additional components (transfer box, mounting extension) are introduced
Solution Approach 1:
The transfer box and mounting extension are merged into a single integrated component. The mounting extension is formed as one piece with the transfer box, combining the cable anchor function and handle mounting function in a single manufactured part, thus reducing the number of separate components while maintaining conversion ease

AI summary
Various methods and systems are provided for dual flush activation. In one embodiment, an assembly includes a handle assembly; and a transfer box configured to detachably connect to an actuation control box of the dual flush toilet system. The transfer box is configured to translate a rotational motion of the handle assembly into a linear motion accepted by the actuation control box to initiate a flush mode of the dual flush toilet system. In another embodiment, an assembly includes a dual-input actuation control box configured to detachably connect to a rotary handle assembly and a push button assembly. The dual-input transfer box is configured to translate a rotational motion of the rotary handle assembly and a liner motion of the push button assembly into a linear motion to initiate a flush mode of the dual flush toilet system.
