Description

Boundary Recognition Flooring Boundary Recognition Flooring The present invention relates to flooring materials. Currently, the flooring industry is evolving with a trend emphasizing smart technology and eco-friendly materials. In particular, as the importance placed on safety and convenience increases, various functional flooring materials are being widely used. Accordingly, there have been proposals for smart flooring materials such as Registered Patent Publication No. 10-2020-0043447, but the prior art including the above prior art document has a pressure sensor unit located between the lower floor layer and the upper floor layer, so the accuracy of the sensor may be reduced depending on environmental factors, and changes in temperature or humidity have a negative effect on the response speed and accuracy of the sensor. Although the upper floor layer functions to distribute the load of heavy objects, it poses a risk of lowering the reliability of pressure detection because the load transmitted to the pressure sensor is not completely blocked under specific conditions. Consequently, the accuracy of real-time data cannot be guaranteed. A structure that includes a lower floor layer, an upper floor layer, a pressure sensor unit, and a shock absorber requires a relatively large installation space. This hinders design flexibility in environments with limited space. FIG. 1 is a perspective view of a boundary recognition flooring material according to an embodiment of the present invention, FIG. 2 is a front view of a boundary recognition flooring material according to an embodiment of the present invention, FIG. 3 is a rear view of a boundary recognition flooring material according to an embodiment of the present invention, FIG. 4 is a left side view of a boundary recognition flooring material according to an embodiment of the present invention, FIG. 5 is a right side view of a boundary recognition flooring material according to an embodiment of the present invention, FIG. 6 is a plan view of a boundary recognition flooring material according to an embodiment of the present invention, FIG. 7 is a bottom view of a boundary recognition flooring material according to an embodiment of the present invention, The boundary recognition flooring of the present invention comprises, as shown in FIGS. 1 to 7, a conductive layer (100), an insulating layer (200), a tactile sensor (300), a power supply unit (400), etc. The conductive layer (100) is located at the top of the flooring material. The insulating layer (200) is located on the conductive layer (100). The above tactile sensor (300) is a sensor connected to the bottom of the insulating layer (200) and is activated whenever the user steps on it through a pressure sensing function. The above power supply unit (400) is located on the side of the flooring material and is composed of a solar panel or a rechargeable battery to supply self-power. The above conductive layer (100) is made of a conductive material so as to transmit a microcurrent when a user steps on it, and acts as a path for current flow when a visually impaired person steps on it, enabling boundary recognition. The above insulating layer (200) acts as an insulator to prevent current from leaking out of the flooring material. At this time, current is allowed to flow only in the conductive layer (100) to prevent energy loss and increase safety. The above tactile sensor (300) detects a microcurrent when a user steps on a boundary area and transmits a tactile signal to the visually impaired person. Multiple sensors are evenly distributed on the flooring to help with accurate boundary recognition. The power supply unit (400) continuously supplies a microcurrent to the tactile sensor (300) and the conductive layer (100), enabling the system to operate autonomously without external power. Below, we will examine the operation process of the present invention composed of the above-described configuration. When a visually impaired person steps on the conductive layer (100), the microcurrent flowing in the upper layer is activated, and the current is detected at the stepping location. The conductive layer (100) provides a current path whenever the user steps on it, thereby transmitting a signal to the tactile sensor (300). Through this, the user feels that a microcurrent is flowing under their feet. The insulating layer (200) prevents microcurrents from leaking out to areas other than the upper layer. This ensures safety by preventing currents from being transmitted to other objects or people outside the flooring material. The insulating layer (200) controls the flow of current to maximize energy efficiency and ensures that currents flow only in the conductive layer (100). The above tactile sensor (300) is activated by detecting an electric current when a user steps on the conductive layer (100). When pressure exceeding a certain level is applied, the sensor recognizes that the user has stepped on a boundary zone and
