Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical devices for motor speed control suffer from errors in wiring and incorrect assignment due to lack of effective coding and alignment mechanisms, leading to inefficiencies in assembly and operation.
Innovation Solution
The electrical device incorporates a connection part with a cover part, featuring coding lugs and guides to ensure correct alignment and coding between printed circuit boards, preventing incorrect wiring and tilting during assembly, utilizing a modular system with coded connections and guides to facilitate precise assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If coding mechanisms and alignment guides are added to prevent wiring errors and tilting, then assembly reliability and connection accuracy are improved, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by incorporating alignment guides and coding mechanisms into the housing structure before assembly. The alignment guides pre-establish the correct positioning path for the cover part, while coding elements on the housing and cover part pre-configure the connection relationship, preventing wiring errors before they occur during assembly operations.
Solution Approach 2:
The patent uses an intermediary approach by introducing alignment guides as mediator elements between the housing and cover part. These guides act as intermediaries that facilitate correct alignment and coding during assembly, enabling reliable connections without requiring complex manual positioning or alignment procedures.
2Manufacturing precision
If coding lugs and alignment guides are integrated into the housing and cover part, then connection accuracy and prevention of tilting are improved, but manufacturing complexity increases
Solution Approach 1:
The patent applies merging by integrating coding lugs, alignment guides, and housing structures into unified components. The coding elements are combined with the housing and cover part manufacturing processes, allowing multiple functions to be achieved through single integrated parts rather than separate assemblies, thereby improving connection accuracy while managing manufacturing complexity.
Solution Approach 2:
The patent implements multi-functionality by designing the housing and cover part to simultaneously serve as structural components, alignment guides, and coding mechanisms. The same parts provide both mechanical support and precise positioning functions, reducing the need for additional specialized components and simplifying the overall manufacturing process.
