Multi-Actuator Wiring Harness for Compact, Reliable Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machines with multiple actuators face issues of increased size due to the need for multiple terminals in daisy-chain connections and reduced reliability due to soldering and branching operations in bus connections, leading to space inefficiencies and decreased reliability.
Innovation Solution
A configuration using filamentary bodies and wiring parts that allow actuators to connect with a single terminal, eliminating the need for soldering and branching, thereby reducing the size and improving reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a daisy-chain connection is used to connect actuators, then the board area and size of each actuator increase due to requiring both input and output terminals, but the connection reliability is maintained
Solution Approach 1:
The patent extracts the output terminal function from each actuator by introducing a separate filamentary body (wiring harness) that carries power and signals from the amplifier to the actuator. This allows each actuator to have only an input terminal while the filamentary body provides the connection path, thereby reducing board area while maintaining connection reliability.
2Area of stationary object
If a bus connection is used to connect actuators, then the board area is reduced by requiring only one terminal per actuator, but the connection reliability decreases due to soldering and branching operations
Solution Approach 1:
The patent introduces a filamentary body (wiring harness) as an intermediary component that physically connects the amplifier to actuators. This intermediary carries power and signals through dedicated conductors, eliminating the need for soldering and branching operations on the actuator itself, thereby reducing board area while maintaining or improving connection reliability.
3Area of stationary object
If bus connection with soldering and branching is used, then the board area is saved, but the machine size increases due to space required for branching operations
Solution Approach 1:
The patent extracts the branching and connection operations from the actuator housing and relocates them to the filamentary body (wiring harness). This allows the actuator itself to be compact with only essential terminals, while the wiring harness handles the complex routing externally, reducing both board area and overall machine size.
4Reliability
If multiple terminals are provided in each actuator for daisy-chain connection, then connection reliability is maintained, but the actuator size and machine size increase
Solution Approach 1:
The filamentary body serves as an intermediary that assumes the role of multiple terminals and connection pathways. By concentrating the connection infrastructure in the wiring harness rather than distributing multiple terminals across each actuator, the patent reduces actuator size and overall machine volume while maintaining reliable connections.
