Awning Motor Connector PCB Assembly for Damage-Free Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing awning devices with roll-up awnings are difficult to install due to the weight and fragility of connectors, which can be damaged during handling and insertion, and require careful manipulation for electrical connections.
Innovation Solution
The use of printed circuit boards with embedded conductors and polymer-encased housings for connectors that provide mechanical and electrical coupling, ensuring robustness and ease of installation by guiding the components during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional connectors are used for electrical coupling, then the connection can be established, but the connectors are fragile and can be damaged or bent during handling and insertion
Solution Approach 1:
The patent combines the electrical connector with a printed circuit board (PCB) to create a robust integrated assembly. The connector is soldered to the PCB, distributing mechanical stresses across the rigid board structure rather than concentrating them on fragile individual contacts. This merging of the connector with the PCB provides both electrical connection and mechanical support, resolving the contradiction between durability and ease of handling.
Solution Approach 2:
The patent employs a composite structure combining the electrical connector, PCB, and housing material. The PCB serves as a rigid substrate that supports the connector elements, while the housing provides additional protection. This composite approach creates a connector assembly that is both durable and easier to handle during installation.
2Productivity
If the canvas packet is inserted into the housing, then the awning is installed, but the connectors may be damaged during the insertion process
Solution Approach 1:
The patent performs preliminary actions by pre-attaching the connector to the PCB and pre-positioning it within the housing structure before the canvas packet insertion. The connector is already in its final position and properly secured to the PCB, so during canvas packet insertion, the connector does not need to be manipulated or positioned, eliminating the risk of damage during the high-speed installation process.
Solution Approach 2:
By merging the connector with the PCB to form a rigid integrated assembly, the patent creates a single robust component that can withstand the forces during canvas packet insertion. This combined structure maintains connector integrity while enabling rapid installation, as the entire assembly moves together as one unit during the insertion process.
3Ease of operation
If the connectors are exposed during insertion, then the electrical connection can be made, but the contact pins are vulnerable to damage and bending
Solution Approach 1:
The patent employs a nested structure where the electrical connector is housed within or integrated with the PCB and housing structure. The connector elements are protected by the surrounding PCB and housing materials, which act as protective casings. This nesting provides both accessibility for electrical connection and robustness against mechanical damage during installation.
Solution Approach 2:
The patent uses a composite construction where the connector is integrated with the PCB and housing materials. The PCB provides a rigid backing and the housing provides additional protection, creating a composite structure that maintains contact pin robustness while allowing necessary electrical accessibility during the insertion process.
