Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projector designs face reliability issues with electrical and mechanical connections to portable media players due to exposed connectors, which are prone to dust adherence and limited design flexibility, leading to unstable connections and operational challenges.
Innovation Solution
A projector design featuring a connecting unit with a rotatable and adjustable mechanism that houses the connector, allowing it to be exposed only when in use, reducing dust exposure and enhancing mechanical stability through a slide mechanism and energizing springs to ensure secure connection and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connector is constantly exposed outside for connection, then ease of operation is improved, but reliability deteriorates due to dust adherence and unstable electrical connection
Solution Approach 1:
The connector is designed to be movable between an exposed state for connection and a retracted state for protection. The elastic member enables the connector to dynamically change its position, being exposed when needed for connection and automatically retracting to protect against dust and external factors, thus resolving the contradiction between ease of operation and reliability
Solution Approach 2:
The elastic member provides self-service by automatically pushing the connector to the exposed position when detached and allowing it to retract when connected, without requiring additional actuation mechanisms. This self-operating system maintains ease of operation while ensuring the connector is protected during non-use periods
2Device complexity
If the connecting unit is fixed at a predetermined position, then device complexity is reduced, but adaptability deteriorates due to limited design freedom
Solution Approach 1:
The connecting unit is designed with rotational freedom, allowing it to pivot between different orientations (horizontal and vertical positions). This dynamic capability provides design flexibility and adaptability for different connection scenarios while maintaining relatively simple structure through the use of a straightforward rotational mechanism with stopping portions
3Device complexity
If the media player is simply connected and fixed, then device complexity is reduced, but reliability deteriorates due to unstable mechanical connection
Solution Approach 1:
The elastic member performs preliminary action by pre-positioning the connector in the exposed state before connection occurs. This ensures that when the media player is connected, the connector is already in the correct position and orientation, facilitating stable mechanical connection without requiring complex fixing mechanisms
Solution Approach 2:
The elastic member acts as a counterbalancing element that opposes the gravitational force and external forces acting on the connected media player. By providing this counteracting force, the system achieves stable mechanical connection while maintaining simple structure without requiring additional heavy-duty fixing components
