Bidet Component Diagnosis Using Sequential Electrical Load Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bidet self-diagnosis methods struggle to accurately diagnose failures in both actively used and non-used parts, often leading to difficulties in identifying specific faulty components and can cause excessive heat generation during testing.
Innovation Solution
A bidet system with a control device capable of performing regular and precise diagnosis modes, using a load input unit to apply a predetermined electrical load to diagnostic target parts, and an output detection unit to determine abnormalities, allowing for sequential testing to prevent heat buildup and accurately identify failed components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If simultaneous testing of multiple parts is performed to diagnose failures quickly, then diagnosis speed is improved, but it becomes difficult to identify a single failed part among tested parts
Solution Approach 1:
The patent segments the diagnosis process into sequential individual tests for each part rather than simultaneous testing. The control device performs tests one part at a time in a predetermined sequence, allowing clear identification of which specific part has failed while still achieving comprehensive diagnosis of all parts including those not currently in use.
2Reliability
If repeated testing is performed on parts that generate excessive heat, then diagnosis thoroughness is improved, but certain parts may fail due to overheating
Solution Approach 1:
The patent implements periodic action by performing tests sequentially with time intervals between them. The control device tests each part individually in a predetermined sequence, allowing heat to dissipate between tests. This periodic testing approach ensures thorough diagnosis while preventing overheating damage that would occur with continuous or repeated testing of the same parts.
3Loss of time
If only parts used in a specific function are tested, then testing time is reduced, but parts not actually used cannot be tested for failure
Solution Approach 1:
The patent applies universality by creating a comprehensive test sequence that covers all parts of the bidet system regardless of which specific function is currently being used. The control device executes a predetermined sequence of tests that includes heating elements, pumps, valves, and other components, ensuring that even parts not currently in use are tested for potential failures.

AI summary
A bidet comprises: one or more part groups including a plurality of element parts; a control device that diagnoses whether the plurality of element parts included in the one or more part groups operate normally according to a diagnosis mode including a regular diagnosis mode for diagnosing whether the one or more part groups are operating normally when in use by a user and a precise diagnosis mode for diagnosing whether the one or more part groups are operating normally when not in use by the user; a load input unit that applies a predetermined electric load for diagnosis to a part to be diagnosed, which is at least one of the plurality of element parts, in the precise diagnosis mode; and an output sensing unit that senses an electrical output value output from the part to be diagnosed when the electric load for diagnosis is applied.
