Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication techniques for electric working machines allow only one-on-one communication between machines, limiting their usefulness for concurrent operation with multiple machines.
Innovation Solution
A communicator with a communication controller that can cyclically transmit operational information without specifying a recipient, enabling unspecified electric working machines to operate in conjunction with a transmission side machine, and allowing users to change operating modes through a manipulator and display information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If one-on-one communication is used between electric working machines, then communication reliability is improved, but adaptability deteriorates
Solution Approach 1:
The communication controller is designed to perform multiple functions: it can operate in specification mode for one-on-one communication and in non-specification mode for broadcasting to multiple machines. This multi-functionality allows the same hardware to adapt to different communication scenarios, resolving the contradiction between reliability and adaptability.
Solution Approach 2:
The communication controller dynamically switches between specification and non-specification modes based on operational requirements. This dynamic adaptability allows the system to maintain reliable one-on-one communication when needed while also supporting multi-machine coordination, thus resolving the contradiction between communication reliability and system adaptability.
2Adaptability or versatility
If operational information is transmitted cyclically without specifying recipient, then adaptability is improved, but use of energy worsens
Solution Approach 1:
The communication controller transmits operational information cyclically at predetermined intervals rather than continuously. This periodic transmission reduces power consumption compared to continuous broadcasting while still maintaining adaptability for multi-machine coordination. The system can operate in non-specification mode for periodic broadcasts or switch to specification mode for targeted communication when energy conservation is prioritized.
3Adaptability or versatility
If communication controller switches between operating modes, then adaptability is improved, but device complexity worsens
Solution Approach 1:
The patent combines the specification and non-specification communication functions into a single communication controller with unified hardware. The controller integrates both communication modes and switches between them based on operational requirements, reducing the need for separate communication systems and minimizing overall device complexity while maintaining adaptability.
