Form-Fitting Contact Plate for Tool-Free Compactor Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for compacting subsoil require tools and additional connecting means for assembly and disassembly of contact plates, leading to workflow interruptions due to the unavailability of necessary tools on construction sites.
Innovation Solution
A device with a contact plate that has a molded connection area extending from the underside of the base plate to enclose it, forming a direct form-fitting connection without separate connecting means, allowing force transmission solely through this positive engagement, enabling assembly and disassembly without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If contact plates are connected to the base plate using separate connecting means (screws, bolts), then the connection strength and reliability are improved, but the device complexity and assembly/disassembly time increase due to requiring additional tools
Solution Approach 1:
The connection area is integrated directly into the contact plate structure, merging the connecting function with the contact plate itself. This eliminates the need for separate connecting means such as screws or bolts, thereby reducing device complexity while maintaining connection reliability through the form-fitting engagement between the connection area and base plate
Solution Approach 2:
The contact plate is designed with a self-connecting capability through its integrated connection area that automatically engages with the base plate during assembly. This self-service mechanism eliminates the need for external connecting means and tools, simplifying the assembly process while ensuring reliable force transmission
2Force
If separate connecting means are used to attach the contact plate, then the force transmission between contact plate and base plate is improved, but the assembly and disassembly time increase due to tool requirements
Solution Approach 1:
The connecting function is merged into the contact plate structure itself through the integrated connection area. This eliminates the need for separate connecting means and tools, enabling rapid assembly and disassembly while maintaining effective force transmission from the base plate to the contact plate during vibration compaction operations
Solution Approach 2:
The contact plate features a self-connecting design where the connection area automatically engages with the base plate during assembly. This self-service mechanism eliminates the time-consuming process of using external connecting means and tools, significantly reducing assembly and disassembly time while ensuring proper force transmission
3Ease of operation
If a form-fitting connection is used between contact plate and base plate, then the ease of assembly and disassembly is improved, but the connection strength may be reduced compared to mechanical fastening
Solution Approach 1:
The connection area is merged into the contact plate structure, creating a form-fitting engagement with the base plate. This integrated design enables easy assembly and disassembly without tools while maintaining sufficient connection strength through the direct geometric interlocking between the connection area and base plate features
Solution Approach 2:
The contact plate employs a self-connecting form-fitting design where the connection area automatically engages with the base plate during assembly. This approach simplifies operation and eliminates tool requirements while providing adequate connection strength for the intended application of transmitting vibrational forces during soil compaction
