Integrated Motor Connection Assembly for Sealed Wire Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motor devices require manual processing of multiple wires, leading to increased labor and risk of sealing failures, as well as potential interference between power and signal wires, which complicates automatic production and signal transmission accuracy.
Innovation Solution
A motor device with a bracket integrally formed with a connection assembly, where at least two wires are externally connected through a single sealing component, using a modular structure that includes a first and second connector, ensuring accurate signal transmission and reducing sealing failure risks by avoiding interference between power and signal wires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple wires are connected through different connectors, then each wire can be externally connected, but the number of sealing structures increases and the risk of sealing failure increases
Solution Approach 1:
The patent combines multiple connectors into a single integrated connection assembly that houses multiple connectors internally. This merging approach reduces the number of external sealing structures from multiple individual connector seals to a single unified sealing component, thereby maintaining external connection capability while improving sealing reliability.
Solution Approach 2:
The connection assembly serves as a universal structure that handles multiple wire connections simultaneously through integrated connectors. This multi-functional design allows power wires, signal wires, and brake wires to be connected through a single assembly with one sealing component, rather than requiring separate connectors for each wire type.
2Ease of operation
If multiple connectors are used for different wires, then each wire can be connected externally, but more labor is required for processing sealing structures
Solution Approach 1:
By merging multiple connectors into a single connection assembly unit, the patent reduces the number of separate sealing operations required during assembly. The integrated design allows workers to install one sealing component rather than multiple individual seals, significantly improving production efficiency while maintaining full wire connection capability.
Solution Approach 2:
The connection assembly is pre-integrated with multiple connectors and wiring arrangements before installation. This preliminary preparation of the connection assembly means that during final assembly, only a single sealing component needs to be installed rather than multiple separate sealing operations, thereby improving productivity.
3Ease of operation
If power wire and signal wire are connected through separate connectors, then each wire can be connected, but interference between wires occurs and signal transmission accuracy decreases
Solution Approach 1:
The patent extracts signal wires from proximity to power wires by routing them through separate internal pathways within the connection assembly. This spatial separation prevents electromagnetic interference between power and signal wires while maintaining flexible external connection capability for both wire types.
Solution Approach 2:
The connection assembly acts as an intermediary structure that provides isolated internal pathways for different wire types. This mediator design allows power wires and signal wires to be externally connected through the same assembly while preventing direct interference by using internal shielding and separation structures.
