Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Angled connectors face challenges in assembly due to their angular shape, which complicates the application of strength and torque in different directions, and can be hindered by existing components or devices in the environment.
Innovation Solution
The angled connector features a unique design with an insertion section and an angled connector section, including key surface pairs and side surfaces that allow for easy assembly using a tool like a fork or mouth key, enabling the application of torque for a secure connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional connector assembly methods are used, then the connector can be assembled, but the angular shape causes forces and torques to act in different directions making assembly difficult and complex
Solution Approach 1:
The connector is divided into separate components: a plug-in section and an angled connector section that can be assembled together. This segmentation allows each part to be optimized independently and simplifies the overall assembly process by breaking down the complex angular connection into manageable parts.
Solution Approach 2:
A tool receiving area is introduced as an intermediary feature on the angled connector section. This recess specifically designed to receive a tool (such as a wrench or spanner) serves as a mediator that enables the application of assembly forces and torques in the correct directions, overcoming the difficulty posed by the angular shape.
2Ease of operation
If support areas are formed on connector components, then tools can be held for applying forces, but the support areas must be structurally feasible while enabling best force application
Solution Approach 1:
The tool receiving area is created as a localized feature with specific geometric properties (recess shape, size, and position) that are optimized for tool engagement. This local modification provides the necessary structural support for tool application without compromising the overall strength and integrity of the angled connector section.
Solution Approach 2:
The tool receiving area utilizes the third dimension by creating a recess that extends into the connector body. This dimensional approach allows the tool to be applied from a specific direction while distributing forces through the structure in a manner that maintains structural feasibility.
3Adaptability or versatility
If the connector has an angular shape, then cable routing and plug-in directions can be separated, but forces and torques must be applied in different directions during assembly
Solution Approach 1:
The tool receiving area serves as a mediator that decouples the angular geometry from the assembly operation. By providing a dedicated interface for tool application, it allows forces and torques to be applied in the correct directions regardless of the angular orientation of the connector sections.
Solution Approach 2:
The tool receiving area is pre-formed on the angled connector section during manufacturing. This preliminary preparation ensures that when assembly is performed, the tool can be immediately applied in the correct orientation without requiring additional setup or adjustment, thereby simplifying the assembly process despite the angular configuration.
