Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional positioning apparatuses in mechanical manufacturing are large, lack precision, and require manual handling, leading to decreased manufacturing efficiency and widened tolerances due to fixed workpiece positioning.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional positioning apparatus is used, then the workpiece can be fixedly placed, but the position and angle cannot be adjusted during manufacturing, decreasing efficiency and requiring widened tolerances
Solution Approach 1:
The positioning apparatus transforms from a static fixed-position design to a dynamic adjustable design. The elevating mechanism enables vertical movement of the workpiece, while the deflection mechanism provides angular adjustment. This allows the workpiece to be positioned at different heights and angles during manufacturing operations, eliminating the need for manual repositioning and maintaining tight tolerances throughout the process.
Solution Approach 2:
The positioning apparatus integrates multiple functions into a single system: it provides both vertical elevation adjustment and angular deflection adjustment. This multi-functional design allows the same apparatus to handle various positioning requirements for different manufacturing operations, replacing multiple separate positioning devices and improving overall manufacturing efficiency.
2Ease of operation
If manual handling is used to process workpiece from different directions, then positioning is simple, but manufacturing efficiency decreases and tolerances must be widened
Solution Approach 1:
The positioning apparatus performs self-adjustment through its elevating and deflection mechanisms, eliminating the need for manual intervention to reposition the workpiece. The system can automatically adjust the workpiece position and angle during manufacturing operations, maintaining both ease of operation and high productivity without requiring operators to manually handle the workpiece from different directions.
3Device complexity
If fixed positioning is used, then the apparatus structure is simple, but precision is low and tolerances must be widened
Solution Approach 1:
The positioning apparatus is divided into distinct functional modules: the elevating mechanism for vertical adjustment and the deflection mechanism for angular adjustment. This segmentation allows each module to be optimized for its specific function while maintaining overall structural simplicity. The modular design enables precise positioning through coordinated action of separate mechanisms without creating excessive complexity.

AI summary
A positioning apparatus includes a base plate and a deflection mechanism mounted upon the base plate. The deflection mechanism includes a stationary platform, a rocker assembly and a deflection platform. The stationary platform is mounted over the base plate for placing and positioning a workpiece. The deflection platform is tiltably mounted over the stationary platform via the rocker assembly and the height of the stationary platform itself is adjustable. The rocker assembly comprises a first rocker and a second rocker of different lengths.
