Solution Overview
Problem
Existing massage apparatuses face challenges in maintaining horizontal alignment between the body and auxiliary portions during use and storage, leading to difficulties in adjusting the height of the auxiliary portion for comfortable use and efficient storage.
Innovation Solution
The massage apparatus features a lifting member that adjusts the height of the auxiliary portion, allowing it to slide horizontally and maintain horizontal alignment with the body portion during use, and reposition above the body portion for storage, using mechanisms like motors, driving shafts, and wheel bracket assemblies to facilitate smooth movement and precise height control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the auxiliary portion is fixed at a certain height, then the structure is simple, but the height cannot be adjusted for different usage scenarios (use and storage)
Solution Approach 1:
The auxiliary portion is designed with a movable structure that can dynamically adjust its height position. A lifting mechanism including a motor, driving shaft, and wheel bracket assembly enables the auxiliary portion to move between a raised position (for storage) and a lowered position (for use), transforming a static structure into a dynamic one that adapts to different operational requirements
Solution Approach 2:
The auxiliary portion serves multiple functions through height adjustment: it supports the lower body during massage treatment when lowered, and can be raised above the body portion for compact storage. The same structural component performs different roles based on its position, eliminating the need for separate storage mechanisms
2Productivity
If the auxiliary portion is raised above the body portion for storage, then storage efficiency is improved, but maintaining horizontal alignment during use becomes difficult
Solution Approach 1:
A detection sensor is integrated into the lifting mechanism to detect the position of the driving shaft. When the driving shaft reaches a predetermined position indicating that the auxiliary portion is properly aligned horizontally with the body portion, the sensor triggers the motor to stop. This feedback control ensures precise horizontal alignment during use while allowing the auxiliary portion to be raised for storage
3Ease of operation
If the auxiliary portion slides horizontally to align with the body portion, then ease of operation is improved, but mechanical reliability may decrease due to sliding mechanisms
Solution Approach 1:
A wheel bracket assembly acts as an intermediary mechanism between the motor-driven lifting system and the auxiliary portion. The wheel brackets engage with guide rails or grooves on the body portion, providing a guided sliding path that reduces friction and wear while maintaining stable horizontal movement. This intermediary structure protects the main lifting mechanism from direct mechanical stress during horizontal positioning
