Slide Shower Gravity Balancer for Stepless Lifting and Constant Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide showers lack stepless lifting and lowering functionality and exhibit significant differences in driving forces for lifting and lowering, leading to discomfort and inefficiency.
Innovation Solution
A gravity balancer system comprising an elastic body and pull ropes, along with a fixed and movable pulley mechanism, is introduced between the fixed portion and the lifting and lowering rod to balance the elastic force and gravity, ensuring constant driving forces and stepless adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a positioning structure with positioning pin and positioning holes is used, then the shower can be fixed at specific positions, but stepless lifting and lowering cannot be achieved
Solution Approach 1:
The patent replaces the static positioning structure (pin and holes) with a dynamic spring-loaded positioning mechanism. The positioning pin is elastically supported and can automatically engage with positioning holes at different heights, allowing the shower to be adjusted to multiple positions while maintaining secure fixation. This dynamic mechanism enables both stepless adjustment capability and reliable positioning at desired heights.
Solution Approach 2:
The patent introduces a spring as an intermediary element between the positioning pin and the rod structure. The spring provides elastic force to push the positioning pin outward for engagement with positioning holes, while also allowing smooth movement between positions. This intermediary mechanism resolves the contradiction by providing both secure positioning and flexible adjustability.
2Device complexity
If the side shower is fixedly disposed below the lifting and lowering rod, then the structure is simple, but the driving forces for lifting and lowering are very different causing discomfort
Solution Approach 1:
The patent applies a spring-loaded counterweight mechanism that provides upward elastic force to balance the downward gravitational force on the lifting and lowering rod. The spring is pre-loaded to generate a counterbalancing force that offsets the weight of the rod and side shower, making the lifting and lowering operations require minimal and nearly constant force throughout the range of motion. This resolves the discomfort caused by varying driving forces while maintaining structural simplicity.

Function Achieved in This Case
The solution enables stepless lifting and lowering with reduced differences in driving forces, enhancing comfort and stability, allowing for precise and adjustable height adjustments.
Implementation Method 1
the function generated by a pulling force applied to the first pull rope (42) and a function of an elastic force generated by the elastic body (41) are opposite
Implementation Method 2
a fixed pulley (43) rotatably assembled to the fixed portion (10)... the second pull rope (44) is connected to the fixed pulley (43) to drive the fixed pulley (43) to rotate in a forward direction; the first pull rope (42) is configured to be pulled and is connected to the fixed pulley (43) to drive the fixed pulley (43) to rotate in a reverse direction
