A shampoo bed

Solution Overview

Problem

Current shampoo beds are inconvenient due to the difficulty in adjusting the shampoo basin position after converting from a chair to a bed, leading to discomfort and increased time consumption, which results in user dissatisfaction.

Innovation Solution

A shampoo bed design featuring a flexibly adjustable shampoo basin connected via rotating shafts and connecting rods, allowing simultaneous adjustment of the back cushion and basin angle, eliminating the need for additional basin position adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the shampoo basin position is adjusted separately after converting from chair to bed, then the basin angle can be adapted, but the operation becomes complex and time-consuming

Engineering Contradiction:

Improvebasin angle adaptabilityVSAvoidoperation complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent combines the back cushion adjustment mechanism and the shampoo basin adjustment mechanism into a single integrated system. When the back cushion angle is adjusted, the shampoo basin automatically adjusts its position and angle through the linkage of connecting rods and rotating shafts, eliminating the need for separate manual adjustment of the basin.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The first connecting rod and second connecting rod serve multiple functions: they transmit the rotation from the first rotating shaft to simultaneously control both the back cushion angle and the shampoo basin position. This multi-functional design allows one adjustment operation to achieve multiple adjustment objectives.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If the shampoo basin position is adjusted separately after converting from chair to bed, then the basin angle can be adapted, but the service time increases

Engineering Contradiction:

Improvebasin angle adaptabilityVSAvoidservice time

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent combines the back cushion adjustment mechanism and the shampoo basin adjustment mechanism into a single integrated system. When the back cushion angle is adjusted, the shampoo basin automatically adjusts its position and angle through the linkage of connecting rods and rotating shafts, eliminating the need for separate manual adjustment of the basin.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The linkage mechanism is pre-configured during manufacturing so that the shampoo basin is automatically positioned correctly whenever the back cushion angle changes. This preliminary setup eliminates the need for operators to perform additional adjustment actions during service.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If the shampoo bed converts from chair to bed form, then comfort is improved, but the shampoo basin angle becomes unsuitable

Engineering Contradiction:

Improveuser comfortVSAvoidbasin angle suitability

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent combines the back cushion adjustment mechanism and the shampoo basin adjustment mechanism into a single integrated system. When the back cushion angle is adjusted, the shampoo basin automatically adjusts its position and angle through the linkage of connecting rods and rotating shafts, eliminating the need for separate manual adjustment of the basin.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The system dynamically adapts the shampoo basin angle based on the back cushion angle. As the back cushion rotates to different positions (chair or bed configuration), the linkage mechanism automatically adjusts the shampoo basin to the appropriate angle, making the system dynamic rather than static.

Inventive Principle:

Principle #15Dynamics

AI summary

This invention discloses a shampoo bed comprising the bed body of shampoo bed, shampoo basin, the first connecting rod that is in rotating connection to the bed body of the shampoo bed via the first rotating shaft, and the second connecting rod that is in rotating connection to the bed body of the shampoo bed via the second rotating shaft. The shampoo basin is in rotating connection to the first connecting rod via the third rotating shaft, and the shampoo basin is in rotating connection to the second connecting rod via the fourth rotating shaft. A back cushion is provided on the first connecting rod. Compared to the current technology, when the first connecting rod of the present utility model is rotated, not only the adjustment of the angle of the back cushion is realized, but also the shampoo basin is lifted and lowered along with the back cushion, so that the adjustment of the angle of the back cushion and the adjustment of the position of the shampoo basin are more convenient, the time for additionally adjusting the position of the shampoo basin is eliminated, which is convenient for the user to use and meets the needs of the user.
