Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for installing a workpiece into another workpiece can cause damage to the second workpiece due to direct collision, especially when using plastic parts, leading to whitening near the impact point.
Innovation Solution
A workpiece assembly device with a body equipped with a limit seat, directional guide grooves, and movable seats driven by mechanisms to guide and support the workpiece for precise alignment and insertion, using internal support components to reduce collision risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If direct push/press method is used to install the first workpiece into the second workpiece, then the assembly process is simple, but the second workpiece is easily damaged and whitening occurs near the impact point
Solution Approach 1:
The patent introduces a movable seat as an intermediary component between the pressing mechanism and the first workpiece. This movable seat absorbs and distributes the impact force during assembly, preventing direct collision damage to the second workpiece while maintaining assembly simplicity
Solution Approach 2:
The movable seat is designed with cushioning capability to preemptively absorb impact forces before they reach the workpieces. This prior cushioning prevents damage during the assembly process while keeping the overall process simple
2Object-affected harmful factors
If a fixture is used to hold the first workpiece for insertion, then the workpiece is protected from damage, but the device complexity increases
Solution Approach 1:
The patent employs a movable seat that can dynamically adjust its position and absorption characteristics during the assembly process. This dynamic approach provides workpiece protection through controlled movement rather than rigid fixture structures, reducing overall device complexity
Solution Approach 2:
The movable seat serves multiple functions: it holds the first workpiece, absorbs impact forces, guides insertion, and protects the second workpiece. This multi-functionality eliminates the need for separate protective fixtures, reducing device complexity
3Productivity
If the movable part is directly pressed into the second workpiece, then the assembly speed is fast, but the collision causes whitening and damage to plastic parts
Solution Approach 1:
The movable seat acts as a mediator between the pressing force and the workpieces, allowing fast assembly while distributing forces to prevent surface damage and whitening of plastic parts
Solution Approach 2:
The movable seat changes the force distribution parameters during assembly, transforming concentrated impact forces into distributed pressures that maintain surface quality while enabling rapid assembly

AI summary
The present invention discloses a workpiece assembly device, wherein a first driving mechanism, a first movable seat, a second driving mechanism, and a second movable seat are arranged to facilitate the back and forth movement of the inner support component in the first direction and in the second direction. The setting of the inner support component facilitates the internal support of the first workpiece and drives the first workpiece to move together; In addition, the setting of the limit seat and the second directional guide groove on it in this case facilitates the positioning of the first and second workpieces during feeding, facilitating subsequent guide movement.
