Digital Key Mesh Routing for Obstacle-Blocked Object Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-frequency signals used by digital keys for data transmission are prone to interference in environments with many obstacles, reducing the effective distance and preventing communication with target objects.
Innovation Solution
A MESH network is configured to include a plurality of objects, allowing control instructions from a digital key to be forwarded through inter-node links to a target object, even when direct high-frequency communication is obstructed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high-frequency signals are used for data transmission between digital key and target object, then data communication capability is improved, but communication reliability deteriorates in environments with many obstacles
Solution Approach 1:
The patent introduces MESH network nodes as intermediary devices between the digital key and target object. When direct high-frequency communication is blocked by obstacles, control instructions are transmitted via multiple hops through intermediate nodes in the MESH network, bypassing the obstructed direct path and maintaining communication reliability.
Solution Approach 2:
The patent transitions from direct one-to-one communication to multi-node networked communication. By adding spatial dimensionality to the communication path through multiple MESH network nodes, the system creates alternative transmission routes that circumvent obstacles blocking the direct line-of-sight path.
2Speed
If direct high-frequency communication link is used between digital key and target object, then communication speed is improved, but communication distance deteriorates in obstructed environments
Solution Approach 1:
The patent divides the direct communication link into multiple segmented hops through MESH network nodes. Each hop maintains high-speed direct communication while the cumulative path length extends the effective communication distance by relaying data through intermediate nodes that are each within high-speed range.
Solution Approach 2:
MESH network nodes serve as intermediary relays that extend communication distance. Each intermediary node receives high-speed data from one node and forwards it to the next, effectively multiplying the communication range while preserving high-speed transmission at each segment.
3Reliability
If MESH network is used to relay control instructions, then communication reliability in obstructed environments is improved, but system complexity increases
Solution Approach 1:
The patent makes existing MESH network nodes (such as smart home devices, vehicles, or infrastructure elements) serve dual functions: their original purposes plus acting as communication relays. This avoids adding dedicated relay hardware and reduces overall system complexity by utilizing multi-functional existing components.
Solution Approach 2:
The MESH network automatically routes control instructions through available nodes without requiring manual configuration or intervention. The network self-organizes and self-manages the relay process, reducing operational complexity despite the increased structural complexity of having multiple nodes.

AI summary
Provided are a method for controlling a target object by using a MESH network, and an object control system. The method may include: a configurator configuring a target object into a MESH network; and sending, by means of the MESH network and to the target object, a control instruction from a digital key corresponding to the target object. In this way, remote control over a target object by using a digital key can be realized.
