Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing clamping devices for workpieces with protection holes require labor-consuming and complicated manual disassembly processes, leading to low efficiency during assembly and disassembly.
Innovation Solution
The clamping device incorporates a supporting seat with L-shaped sliding grooves, movable clamping subassemblies, and an operation assembly with a locking member and transmission pin, allowing for automatic latching and unlatching of the clamping subassemblies into and out of the protection holes, facilitated by a rotating knob and spiral protrusions, which simplifies the assembly and disassembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual disassembly of the pressing plate and clamping assemblies is used, then the structure remains simple, but the operation becomes labor-consuming and efficiency decreases
Solution Approach 1:
The pressing plate is designed to be movable rather than fixed, allowing it to be automatically pushed by the operation assembly during disassembly. This dynamic design enables the pressing plate to move from its initial position to push the clamping assemblies out, transforming a static manual operation into a dynamic automated process that improves efficiency without requiring complex additional mechanisms
Solution Approach 2:
The operation assembly is designed to automatically push both the pressing plate and clamping assemblies during disassembly without requiring separate manual operations. The system serves itself by using the same operational mechanism to accomplish multiple disassembly tasks sequentially, reducing labor consumption while maintaining structural simplicity
2Ease of operation
If manual disassembly operations are used, then the device structure remains simple, but the operation process becomes complicated and time-consuming
Solution Approach 1:
The operation assembly merges the functions of disassembling the pressing plate and the clamping assemblies into a single integrated operation. When the operation assembly moves, it simultaneously pushes the pressing plate and the clamping assemblies through the protection holes, combining multiple discrete manual steps into one unified action that is both easier to operate and faster to execute
Solution Approach 2:
The pressing plate is pre-positioned and designed to automatically push the clamping assemblies during its movement. This preliminary positioning allows the pressing plate to serve as an automatic pushing mechanism for the clamping assemblies, eliminating the need for separate manual pushing operations and reducing both operational complexity and time

AI summary
Clamping device for clamping a workpiece defining at least three protection holes, includes a supporting seat, a pressing plate, a clamping assembly, and an operation assembly. The supporting seat can define a sliding groove, a first receiving groove, a second receiving groove, and a receiving hole, and includes a protrusion portion. The pressing plate can be securely stacked upon the supporting seat. The clamping assembly can include a first and a second clamping subassembly, and is sandwiched between the supporting seat and the pressing plate. The operation assembly can include a locking member and a transmission pin eccentrically assembled to an end of the locking member. When the locking member is rotated, the transmission pin can be driven to resist the second clamping subassembly to be partially exposed from the supporting seat, simultaneously. The locking member can resist the first subassembly to be partially exposed from the supporting seat.
