Handheld Bidet with Angled Sprayer Head for Seated Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handheld bidet systems are not ergonomically designed for use on toilets, making it difficult for users with disabilities or limited mobility to clean effectively, and they lack a discreet and aesthetically pleasing storage solution.
Innovation Solution
A handheld bidet apparatus with an angled sprayer head and trigger on the same side as the water flow, allowing for easier use while seated, and a swiveling mechanism, combined with a mounting base that can be concealed to match bathroom fixtures, providing improved ergonomics and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a traditional sprayer design with trigger on the opposite side is used, then the sprayer can be manufactured with standard designs, but it becomes difficult to operate while seated and requires awkward hand positions
Solution Approach 1:
The sprayer is designed with asymmetric placement of the trigger mechanism on the same side as the spray head, rather than the traditional opposite side configuration. This asymmetric design allows the user to operate the trigger with the same hand that holds the sprayer, enabling effective bidet use while seated without requiring awkward hand positions or cross-body movements.
Solution Approach 2:
The conventional sprayer design is inverted in terms of trigger placement. Instead of placing the trigger on the opposite side from the spray head (traditional design), the trigger is positioned on the same side, fundamentally changing the operational mechanics to suit seated bidet use while maintaining manufacturing feasibility.
2Ease of manufacture
If the spray head is positioned at the terminal end of the sprayer, then the design follows conventional sprayer patterns, but the water spray angle is not ergonomic for bidet use
Solution Approach 1:
The spray head is positioned at a specific location on the angled portion of the sprayer body rather than at the terminal end, creating a localized optimal spray angle. This local quality adjustment ensures that water is discharged at an ergonomic angle specifically suited for bidet cleaning while maintaining overall design simplicity and manufacturability.
Solution Approach 2:
The sprayer incorporates an angled portion that can be adjusted or positioned to optimize the spray angle dynamically during use. This allows the water discharge angle to adapt to the user's position and cleaning needs, improving ergonomics while maintaining a relatively simple overall structure.
3Ease of manufacture
If a simple hook-type mounting is used, then the installation is simple, but the sprayer appearance is not disguised and lacks aesthetic appeal
Solution Approach 1:
The mounting base serves multiple functions: it provides secure attachment of the sprayer, offers a concealed storage location that disguises the bidet system's presence, and can be designed to match bathroom aesthetics. This multi-functional design maintains installation simplicity while adding aesthetic value and discrete storage capability.
Solution Approach 2:
The sprayer nests within or upon the mounting base when not in use, with the mounting base providing a concealed housing that hides the sprayer's presence. This nesting arrangement allows the bidet system to blend with bathroom fixtures while remaining easily accessible when needed.
4Ease of operation
If elaborate cabinets or special toilet tanks are used to house the bidet system, then the sprayer is concealed aesthetically, but the installation requires substantial space and complex modifications
Solution Approach 1:
The concealment function is extracted from complex structures like cabinets or special toilet tanks and implemented through a simple, standalone mounting base. This extracted solution provides aesthetic concealment and discrete storage without requiring substantial space or complex plumbing modifications, maintaining installation simplicity while achieving the desired aesthetic effect.

AI summary
An ergonomically designed hygienic sprayer or bidet apparatus for use with pre-existing fixtures. The sprayer includes an angled portion with a sprayer head disposed on an underside of the angled portion, resulting in a flow of water from the sprayer head that is substantially between 30° and 60° relative to a longitudinal axis of a body portion of the sprayer. The sprayer also includes an actuator located on the same side of the sprayer as the sprayer head and slip-resistance surfaces. An optional mounting base for securely holding a hygienic sprayer in a manner that may disguise its presence or be more aesthetically pleasing. The mounting base is substantially the same size as the hygienic sprayer. The mounting base may be mounted or secured to multiple types of surfaces near the fixture with which the hygienic sprayer is used.
