Adjustable Ear Positioning Mechanism for Electronic Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional positioning mechanisms for man-made ears are inflexible and require redesigning when the type of electronic device being tested changes, leading to inefficiencies in time and resources.
Innovation Solution
A positioning mechanism comprising a shaft, driving device, rotational arm, and sliding members that allow for adjustable positioning of a man-made ear, enabling it to move along with the driving device and sliding members, accommodating different electronic device sizes without the need for extensive redesign.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional positioning mechanisms are designed for certain device types, then positioning accuracy for specific devices is achieved, but adaptability to different device sizes is lost
Solution Approach 1:
The positioning mechanism employs adjustable components including a movable support arm with telescopic sections, adjustable height columns, and reconfigurable fastening systems that enable the same mechanism to accommodate multiple electronic device types and sizes without requiring redesign, thereby achieving universal adaptability
2Productivity
If positioning mechanism is redesigned for each device type, then optimal positioning is achieved, but time and resource efficiency deteriorates
Solution Approach 1:
The positioning mechanism incorporates dynamically adjustable elements including telescopic support arms with variable lengths, height-adjustable columns, and reconfigurable fastening systems that can be modified in real-time to suit different device types, eliminating the need for complete redesign while maintaining optimal positioning capability
3Ease of operation
If fixed positioning mechanism is used, then manufacturing simplicity is maintained, but flexibility in positioning is reduced
Solution Approach 1:
The positioning mechanism is divided into modular segments including telescopic support arms with separate extendable sections, independently adjustable height columns, and discrete fastening components that can be easily assembled and configured, maintaining manufacturing simplicity while providing positioning flexibility through modular reconfiguration

AI summary
A positioning mechanism for a man-made ear includes a shaft, a driving device, a rotational arm, a first sliding member, and a second sliding member. The driving device is slidably secured to the shaft by a first fastener. The driving device also has a rotational wheel. The rotational arm has an end secured to the rotational wheel. The first sliding member has a first elongated sliding groove adjustably secured to the rotational arm by a second fastener inserted through the first elongated sliding groove. The second sliding member has one or more second elongated sliding grooves perpendicular to the first elongated sliding groove. The second sliding member is adjustably secured to the first sliding member by one or more third fasteners inserted through the one or more second elongated sliding grooves. The second sliding member is configured for securing a man-made ear.
