Innovation Solution
An electrocardiogram converting device with a rotatable connector and extension cable, featuring a casing with perpendicular and parallel surfaces, includes a chest lead connection module and a limb lead connection module with banana sockets and color recognition rings, allowing for flexible placement and easy connection of ECG cables, reducing volume and improving accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the ECG measurement instrument is located on the right side or left side of the patient according to site limitation, then the measurement can be performed, but the connection between the ECG cable and electrode patch becomes inconvenient and time-consuming
Solution Approach 1:
The patent applies the dynamics principle by making the connector rotatable rather than fixed. The connector can rotate to different angles (0°, 45°, 90°, 135°, 180°) to adapt to different spatial positions of the ECG instrument relative to the patient. This dynamic adjustment capability allows the connector to maintain optimal connection orientation regardless of instrument placement, thereby improving connection convenience and reducing connection time.
Solution Approach 2:
The patent changes the orientation parameter of the connector by allowing rotation across multiple angular positions. This parameter change enables the connector to adapt to various spatial configurations between the ECG instrument and electrode patch, resolving the contradiction between instrument placement flexibility and connection convenience.
2Ease of operation
If multiple ECG connectors are arranged on the same surface of the casing, then all connections are accessible, but the device volume increases and spatial arrangement becomes complex
Solution Approach 1:
The patent transitions from a two-dimensional arrangement of connectors on a single surface to a three-dimensional distribution across multiple surfaces (front, back, left, right). By placing chest lead connectors on one surface and limb lead connectors on another surface, the patent reduces the footprint on any single surface while maintaining all connector accessibility, thereby reducing overall device volume and simplifying spatial arrangement.
Solution Approach 2:
The patent segments the connector arrangement by function and spatial location. Chest lead connectors (V1-V6) are grouped on one surface while limb lead connectors (LA, RA, LL, RL) are grouped on another surface. This segmentation allows each surface to have a manageable number of connectors, improving accessibility while controlling device volume.
3Adaptability or versatility
If the connector is fixed in position, then the structure is simple, but the device cannot be placed flexibly relative to the patient
Solution Approach 1:
The patent introduces rotational dynamics to the connector structure, allowing it to change orientation while maintaining a relatively simple overall design. The rotatable connector with angle limiting mechanism provides placement flexibility without requiring complex multi-component assemblies, thus achieving adaptability with controlled complexity.

AI summary
An electrocardiogram converting device includes a casing, a first connector, a chest lead connection module, and a limb lead connection module. The casing includes a first surface, a second surface, and a third surface. The first connector is installed on the first surface of the casing, the chest lead connection module is installed on the second surface of the casing, and the limb lead connection module is installed on the third surface of the casing. In addition, the second surface is perpendicular to the third surface, and the first surface is parallel to the third surface, so as to reduce a length and a volume of the electrocardiogram converting device and improve the convenience of electrocardiogram measurement.
