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 impact energy through controlled movement and guides the workpiece along a predetermined trajectory, preventing direct collision damage to the second workpiece while maintaining assembly efficiency
Solution Approach 2:
The patent implements preliminary positioning actions through guide grooves and positioning structures before the actual pressing operation. The first workpiece is pre-aligned and guided into the correct position, ensuring that the pressing force is applied evenly and preventing misalignment-induced damage during assembly
2Reliability
If a fixture is used to hold the first workpiece for insertion, then the workpiece can be securely held, but the device structure becomes more complex
Solution Approach 1:
The patent replaces static fixtures with a dynamic movable seat that can move along guide grooves. This dynamic structure provides reliable workpiece holding during insertion while reducing overall system complexity by eliminating the need for complex fixed fixture arrangements. The movable seat adapts to the workpiece position through controlled movement rather than rigid constraint
Solution Approach 2:
The movable seat serves multiple functions: it holds the first workpiece, guides its movement along the insertion trajectory, absorbs impact energy, and can be reset for repeated operations. This multi-functionality replaces what would otherwise require multiple separate components (fixture, guide, cushioning element), thereby reducing device complexity while maintaining reliability

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.
