Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible material is used for the housing, then the device can adapt to body contours, but the negative and positive pressure at the sucking opening is reduced
Solution Approach 1:
The housing is divided into a rigid housing and a flexible covering. The rigid housing maintains structural integrity and pressure generation, while the flexible covering provides adaptability to body contours. This segmentation allows each part to fulfill its specific function without compromising the other.
Solution Approach 2:
A flexible covering is added over the rigid housing to provide adaptability to body contours. This flexible shell maintains the sealing effect while allowing the housing to conform to the user's body shape, solving the contradiction between rigidity for pressure maintenance and flexibility for adaptability.
2Reliability
If the first through hole center line is spaced apart from the first sucking opening center line, then the adsorption effect is improved, but the structural complexity increases
Solution Approach 1:
The first through hole is intentionally positioned asymmetrically relative to the first sucking opening, with its center line spaced apart from the sucking opening center line. This asymmetric arrangement creates a more effective pressure differential and improves adsorption effect, while the offset position is achieved through straightforward manufacturing processes.
3Stress or pressure
If a piston reciprocating mechanism is used, then strong negative and positive pressure is generated, but the device complexity increases
Solution Approach 1:
A piston reciprocating mechanism is employed to generate periodic strong negative and positive pressure at the sucking opening. The piston's back-and-forth motion creates alternating pressure cycles that enhance adsorption effect. The periodic action is achieved through a motor-driven crankshaft mechanism that converts rotational motion into linear piston reciprocation.
Solution Approach 2:
The piston reciprocating mechanism utilizes pneumatic principles to generate pressure differential for adsorption. The piston's movement within the receiving space creates pressure changes that are transmitted through the first through hole to the sucking opening, enabling strong adsorption effect without complex mechanical structures.
4Reliability
If sealing rings are added between the piston and receiving part, then pressure leakage is prevented, but the manufacturing complexity increases
Solution Approach 1:
Sealing rings are installed between the piston and receiving part to prevent pressure leakage. These flexible sealing elements create effective seals that maintain pressure differential during piston reciprocation. The sealing rings are simple circular components that can be easily manufactured and installed, adding minimal complexity while ensuring reliable pressure maintenance.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The massager achieves a better adsorption effect by maintaining strong negative and positive pressure, providing enhanced relief for body fatigue and soreness.
Implementation Method 1
the driving element is configured to drive the piston to reciprocate in the receiving space to periodically generate a negative pressure and a positive pressure at the first sucking opening
Implementation Method 2
an outer surface of the piston is sleeved with at least one sealing ring, and the at least one sealing ring is arranged between the outer surface of the piston and an inner wall of the receiving part
Implementation Method 3
The rigid housing is not prone to deform, so as to avoid the negative pressure and the positive pressure at the first sucking opening from being decreased
