Rotating Functional Module With Integrated Motor Output Shaft
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The miniaturization of functional modules within smartphones is hindered by the need for external motor-driven rotation mechanisms, which increase gear sets and lead to backlash accumulation, occupying valuable internal space and increasing production costs.
Innovation Solution
Incorporating a motor assembly with an output shaft that protrudes from the housing, allowing the functional module to rotate relative to the body, thereby reducing the number of gear sets and eliminating backlash while saving space and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an external motor-driven rotation mechanism is used to rotate the functional module, then the rotation function is achieved, but the number of gear sets increases and backlash accumulation occurs
Solution Approach 1:
The motor assembly is merged with the functional module housing, integrating the motor directly into the module structure. This eliminates the need for separate external motor mounting and reduces the number of intermediate gear sets required for rotation, thereby simplifying the overall device complexity while maintaining the rotation function.
Solution Approach 2:
The output shaft of the motor assembly serves as an intermediary element that directly connects the motor to the functional module's rotation mechanism. This direct connection minimizes the number of gear sets and reduces backlash accumulation by eliminating intermediate transmission stages.
2Ease of operation
If conventional external motor-driven rotation is used, then the functional module can rotate, but valuable internal space is occupied
Solution Approach 1:
The motor assembly is nested within the functional module housing, with the motor and its components arranged in a compact, space-efficient configuration. The output shaft protrudes from the housing to enable rotation while the motor itself occupies minimal space within the module's internal volume, preserving valuable smartphone internal space.
3Ease of operation
If conventional rotation mechanisms with multiple gear sets are used, then rotation is achieved, but production costs increase
Solution Approach 1:
The design extracts and eliminates unnecessary intermediate gear sets from the rotation mechanism, retaining only the essential motor assembly and output shaft. This reduction in component count directly lowers production costs by reducing the number of parts that need to be manufactured, assembled, and quality-checked.
Solution Approach 2:
The invention discards the conventional approach of using multiple gear sets for rotation, opting instead for a simplified motor assembly with a direct-output shaft. This elimination of redundant components reduces both material costs and manufacturing complexity, leading to lower production costs.
