Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic chest percussion machines lack adjustable clapping travel and buffering, making them inefficient and uncomfortable for patients, as they are unable to detect and adjust to individual body shapes and do not provide adequate force control, which can lead to inadequate phlegm loosening or tissue damage.
Innovation Solution
A back clapping machine with a movement mechanism using a gear, motors, a rack, and an infrared detector to adjust clapping travel, combined with a buffer unit and a clap mechanism to provide a shock-absorbing effect, mimicking hand-like clapping motions while preventing pressure ulcers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional automatic chest percussion machine uses fixed clapping travel, then the structure is simple, but it cannot adapt to individual body shapes and provides inadequate force control
Solution Approach 1:
The patent implements a dynamic clapping travel adjustment mechanism where the clap mechanism can automatically adjust its travel distance based on real-time detection of the patient's back surface. The detection unit measures the distance between the clap head and the back surface, and the control unit adjusts the clapping travel accordingly, transforming the fixed structure into a dynamic, adaptive system that conforms to individual body shapes.
Solution Approach 2:
The patent employs a feedback control system where the detection unit continuously monitors the distance between the clap head and the patient's back surface during operation. This distance information is fed back to the control unit, which then adjusts the clapping travel in real-time to maintain optimal contact force, ensuring both adaptability to individual body shapes and precise force control.
2Object-affected harmful factors
If conventional automatic chest percussion machine lacks buffering function, then the structure is simple, but it causes tissue damage and pressure ulcers
Solution Approach 1:
The patent incorporates a buffer unit between the clap head and the patient's back surface that provides beforehand cushioning. This buffer unit is designed to absorb and attenuate the impact force during clapping, preventing excessive force from reaching the patient's skin and tissues, thereby preventing pressure ulcers and tissue damage before they occur.
Solution Approach 2:
The patent changes the physical parameters of the clapping system by introducing a buffer unit that modifies the force transmission characteristics. The buffer unit alters the impact force parameter, transforming it from a potentially harmful high-force impact into a controlled, attenuated force that is safe for patient tissue while still effective for phlegm loosening.
3Productivity
If manual chest percussion is used, then the device is simple, but it is time and manpower consuming and difficult to control force properly
Solution Approach 1:
The patent implements a self-service automatic control system where the detection unit automatically detects the patient's back surface characteristics and the control unit automatically adjusts the clapping parameters without requiring manual intervention. This self-service capability eliminates the need for continuous manual operation while maintaining proper force control, significantly improving treatment efficiency.
Solution Approach 2:
The patent replaces the manual mechanical clapping operation with an automated electromechanical system. The motor-driven clap mechanism, controlled by electronic detection and control units, substitutes for manual hand clapping, eliminating the need for continuous human involvement while maintaining or improving force control precision.

AI summary
A back clapping machine with chest percussion function includes a casing, a movement mechanism, a clap mechanism, and a buffer unit. The casing includes an outer cover, a rear cover, and a housing space therein, in which the movement mechanism is disposed. The clap mechanism is in the housing space and connected with the front lateral side of the movement mechanism. The buffer unit is in the housing space and arranged to elastically abut against the outer cover and the rear cover therebetween. Thus, the present invention automatically carries out back clapping operation and detects the distance for back clapping, also provides a shock buffering effect, thus achieving a back clapping chest percussion operation through a hand alike structure and preventing pressure ulcer.
