Solution Overview

Problem

Existing bidet filters are visually unappealing when installed near the toilet seat and difficult to replace due to limited space and the need to disassemble bidet body parts.

Innovation Solution

A detachable upper opening/closing-type controller allows a capsule type bidet filter to be coupled to the upper portion of the bidet controller, enabling easy replacement and control over water supply, featuring a controller main body, water supply part, operation part, and a filter detachable frame for purification and sealing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the bidet filter is installed on the pipe connected to the water hydrant, then the filter can be positioned near the toilet seat, but it becomes visually unappealing and difficult to replace

Engineering Contradiction:
Improveease of replacementVSAvoidinstallation complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The bidet filter is segmented into a detachable capsule type that can be easily removed and replaced. The filter body is separated from the bidet main body, allowing independent replacement without disassembling the entire bidet system. This segmentation enables users to easily access and replace the filter while maintaining a clean integrated appearance when assembled.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

An intermediary coupling mechanism is introduced between the filter and the bidet main body. This coupling structure serves as a mediator that allows easy detachment for replacement while maintaining a secure and aesthetically pleasing connection during normal use. The intermediary component simplifies the replacement process without requiring complex disassembly of the bidet body.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the bidet filter is installed in a small space near the toilet seat, then it can be positioned conveniently, but replacement becomes difficult due to limited access

Engineering Contradiction:
Improveease of replacementVSAvoidinstallation space
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The filter is designed as a separable capsule that can be independently removed from the bidet main body. This segmentation allows the filter to be accessed and replaced even in confined spaces, as users only need to access the filter portion rather than disassembling the entire bidet assembly. The compact capsule design fits within limited spaces while maintaining replaceability.

Inventive Principle:
Principle #1Segmentation

3Ease of repair

If the bidet filter is made detachable for regular replacement, then maintenance becomes easier, but the assembly and replacement process becomes more complex

Engineering Contradiction:
Improveease of maintenanceVSAvoidassembly complexity
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The filter is designed as a self-contained detachable capsule with integrated components. This segmentation allows the entire filter assembly to be replaced as a single unit without complex sub-assembly or disassembly procedures. The capsule type design incorporates all necessary components within the filter body, simplifying the replacement process to a single coupling action while maintaining ease of maintenance.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The filter is designed as a disposable or frequently replaceable capsule unit. By designing the filter as a complete, self-contained capsule that can be easily replaced, the system prioritizes ease of maintenance over assembly complexity. The capsule is intended to be replaced regularly without requiring complex reassembly procedures, aligning with the principle of using simple, replaceable components for maintenance-critical parts.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)
