Solution Overview
Problem
Existing indoor positioning systems using leaky cables suffer from severe multi-path effects, leading to positioning jitter and poor accuracy due to continuous slots acting as leakage points for positioning signals.

Engineering Contradiction Analysis
1Area of stationary object
If continuous slots are set in the leaky cable for leaking positioning signals, then the coverage area is improved, but the multi-path effect becomes severe leading to positioning jitter and poor accuracy
Solution Approach 1:
The leaky cable is segmented into alternating positioning modules and non-positioning modules. The positioning modules contain slots for signal leakage, while non-positioning modules have no slots. This segmentation creates distinct transmission paths with identifiable characteristics, allowing the receiving end to distinguish and select valid positioning signals, thereby reducing multi-path effects and improving positioning accuracy while maintaining adequate coverage through the distributed positioning modules.
2Area of stationary object
If continuous slots are provided along the leaky cable, then signal transmission coverage is enhanced, but transmission paths become indistinguishable causing positioning jitter
Solution Approach 1:
The cable is divided into discrete positioning modules with slots and non-positioning modules without slots. This creates a patterned structure where signal leakage occurs only at specific intervals. The receiving end can identify transmission paths by detecting signals from these distinct positioned modules, stabilizing positioning results and eliminating jitter caused by indistinguishable continuous paths.
Solution Approach 2:
Different sections of the cable have different properties: positioning modules have slot structures that allow signal leakage, while non-positioning modules have sealed structures that prevent leakage. This local differentiation creates identifiable signal characteristics at specific locations, enabling the system to distinguish transmission paths and improve positioning stability while maintaining overall coverage.

AI summary
A leakage apparatus, a positioning method, and an electronic device are provided. The leakage apparatus (20) includes at least one positioning module (21) and at least one non-positioning module (22), at least one positioning area being provided in the positioning module (21); where, the positioning module (21) is connected with the non-positioning module (22), the positioning area in the positioning module (21) is configured to leak a positioning signal, a range obtained by superimposing a coverage area of the positioning signal leaked by each positioning module (21) in a longitudinal direction covers an area where the leakage apparatus (20) is located, the longitudinal direction referring to an extension direction of the leakage apparatus (20). By arranging the positioning modules (21) in the leakage apparatus (20) at intervals, transmission paths of the positioning signal leaked by different positioning modules (21) are obviously different, so that accurate positioning can be performed on the basis of the characteristics of the transmission paths of the positioning signals.
