Solution Overview

Problem

Current shower systems with multi-segment pipe designs occupy excessive packaging space and limit water pressure capacity, and connections are prone to displacement over time.

Innovation Solution

A telescopic installation structure featuring an inner and outer pipe that slide relative to each other, with sealed and secure connections, and a rotating joint allowing height adjustment and rotation, secured by a seat, and a seat, and a rotating joint allowing height adjustment and rotation, secured to the top spray pipe and seat.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multi-segment pipe designs are used to accommodate adjustable installation heights, then adaptability to different installation requirements is improved, but packaging volume increases excessively and water pressure capacity is limited

Engineering Contradiction:
Improveadjustable installation heightVSAvoidpackaging volume
Core Design Contradiction:
Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The inner pipe is nested within the outer pipe, allowing the telescopic installation structure to be compact during packaging while enabling height adjustment during installation. The inner pipe can slide within the outer pipe to achieve different installation heights, and the nested configuration significantly reduces packaging volume compared to multi-segment pipe designs.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If multi-segment pipe designs are used for height adjustment, then adaptability to different installation requirements is improved, but the structure becomes more complex and connection points are prone to displacement

Engineering Contradiction:
Improveadjustable installation heightVSAvoidpipe structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The nested pipe structure replaces multiple separate pipe segments with a single integrated telescopic mechanism. The inner pipe slides within the outer pipe, eliminating the need for multiple connection points and reducing structural complexity while maintaining height adjustability.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The telescopic installation structure employs a dynamic sliding mechanism where the inner pipe can move relative to the outer pipe to achieve height adjustment. This dynamic design replaces static multi-segment connections with a single continuous water flow path, reducing connection points and improving reliability.

Inventive Principle:
Principle #15Dynamics

3Volume of stationary object

If telescopic structure with inner and outer pipe is used, then packaging volume is reduced, but sealed connection between pipes must be maintained during sliding

Engineering Contradiction:
Improvepackaging volumeVSAvoidsealed connection reliability
Core Design Contradiction:
Volume of stationary objectVSReliability

Solution Approach 1:

The inner pipe is nested within the outer pipe with sealing elements positioned at the interface between the two pipes. The sealing structure maintains water-tight connections during the sliding operation, allowing the telescopic mechanism to achieve compact packaging while preserving connection reliability.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

A telescopic installation structure for a shower head includes a main water pipe (1), a top spray pipe (2), and a seat (3). The main water pipe includes an inner pipe (4) and an outer pipe (5). The inner pipe (4) is arranged within the outer pipe (5). One end of the inner pipe (4) is sealed and connected to the outer pipe (5), and another end is sealed and secured to the seat (3). A rotating joint (6) is arranged between the top spray pipe (2) and the seat (3) to allow them to be rotatable to each other. The rotating joint (6) is secured to the top spray pipe (2) and the seat (3), and the inner pipe (4) and the outer pipe (5) are in communication with the top spray pipe (2) via the seat (3). When packaging before installation, the inner pipe is within the outer pipe. When installing, the relative position between the inner pipe and the outer pipe can be adjusted based on a required height.
