Wall-mounted flush toilet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wall-mounted flush toilets fail to illuminate the floor surface region directly under the toilet main body and behind the discharge trap, leading to inadequate lighting in these areas.
Innovation Solution
A wall-mounted flush toilet design with an illuminating device positioned within the internal space behind the lowermost end of the discharge trap and above the skirt, allowing light to be emitted to the floor surface without being blocked, and featuring a translucent cover with a single, integral surface to enhance cleanability and prevent dirt accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the illuminating device is provided forward of the lower surface of the toilet main body and the lowermost end of the discharge trap, then the illuminating device can be easily installed and maintained, but the floor surface region directly under the toilet main body and behind the lowermost end of the discharge trap cannot be irradiated
Solution Approach 1:
The illuminating device is repositioned from a forward location to a rearward location within the internal space of the toilet main body, specifically behind the lowermost end of the discharge trap. This spatial reconfiguration in the rearward dimension enables the light to reach the previously inaccessible floor region directly under the toilet main body, thereby expanding illumination coverage without compromising installation accessibility through the rear wall.
2Illumination intensity
If the illuminating device is provided within the internal space behind the lowermost end of the discharge trap, then the floor surface region directly under the toilet main body can be irradiated, but the illuminating device becomes hidden from user's view
Solution Approach 1:
The illuminating device is nested within the internal space of the toilet main body, specifically positioned behind the lowermost end of the discharge trap and above the lower end of the skirt. This nesting arrangement allows the illuminating device to be concealed from external view while remaining functional, as it operates within the existing structural cavity of the toilet main body.
3Illumination intensity
If the illuminating device is positioned away from the floor surface, then the light is not blocked and can emit to the floor surface region, but the device requires more internal space
Solution Approach 1:
The illuminating device is positioned at a specific location within the internal space - behind the lowermost end of the discharge trap and above the lower end of the skirt. This localized positioning optimizes the balance between maintaining sufficient distance from the floor surface for unobstructed light emission and minimizing occupation of the internal space by utilizing the existing void area.

Function Achieved in This Case
The design effectively illuminates the predetermined floor surface region with a gradation pattern, enhancing the appearance and aesthetics of the toilet while preventing urine splash and bounce by guiding users to the correct position.
