Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bidet drying devices have limited drying efficiency due to a fixed duct position and ineffective nozzle movement, leading to incomplete drying and potential contamination from foreign substances.
Innovation Solution
A rotary drying nozzle with a ventilation groove and driving motor that moves forward and backward, allowing for wider coverage and integration with a bidet device, including a heating member to adjust airflow temperature and a drainage unit to prevent water ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a fixed duct is used to discharge air flow, then the structure is simple, but the drying range is limited due to long distance from drying area
Solution Approach 1:
The duct is designed to rotate together with the drying nozzle assembly, transforming from a fixed structure to a dynamic one. This allows the air discharge outlet to continuously sweep across the drying area, significantly expanding the effective drying range while maintaining structural simplicity through integrated rotation.
Solution Approach 2:
The rotating duct assembly serves multiple functions: it discharges air flow over a wide area, rotates to cover different zones, and integrates with the nozzle retraction mechanism. This multi-functionality expands the drying coverage without requiring separate components for each function.
2Area of stationary object
If the drying nozzle is simply elongated and retracted, then the structure is simple, but the drying area is not effectively increased and foreign substances cause contamination
Solution Approach 1:
The drying nozzle is designed to rotate while elongating and retracting, transforming from simple linear movement to a combined rotational-linear motion. This dynamic movement pattern expands the drying area coverage and prevents foreign substance accumulation by continuously varying the nozzle's position and orientation.
Solution Approach 2:
The nozzle movement is extended from one-dimensional linear retraction to two-dimensional rotational-sweeping motion. This adds a rotational dimension to the nozzle's operation, allowing it to cover a much larger area and effectively prevent contamination by constantly changing its discharge position.
3Productivity
If the drying nozzle is moved closer to the drying area, then drying efficiency is improved, but the risk of water ingress and product failure increases
Solution Approach 1:
The drainage unit is pre-configured with water drainage holes and a collection chamber positioned to receive and drain water before it can enter the internal components. This preliminary drainage action prevents water ingress and potential product failure even when the nozzle operates close to the drying area.
Solution Approach 2:
The drainage unit acts as an intermediary component between the external environment and the internal electronics. It intercepts and removes water through drainage holes and collection chambers, preventing direct contact between water and sensitive components, thus maintaining reliability.
4Reliability
If the ventilation groove is not cleaned, then the structure is simple, but foreign substances accumulate causing contamination and reduced hygiene
Solution Approach 1:
The ventilation groove is designed with self-cleaning capability through integrated drainage holes that allow water to flow through and flush away accumulated foreign substances. The structure uses its own operational water flow to clean itself, maintaining hygiene without requiring external cleaning mechanisms.
Solution Approach 2:
The drainage system extracts and removes foreign substances from the ventilation groove by channeling water flow through drainage holes and out through the collection chamber. This extraction mechanism continuously clears contaminants, maintaining hygiene with minimal structural addition.
