Device for connecting a front with a frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing front connection devices struggle to reliably and cost-effectively connect fronts of varying heights to frames, leading to high leverage forces and potential detachment issues when handling high fronts, as standard frames are not adaptable to high fronts without additional costly modifications.
Innovation Solution
A device featuring a fastening attachment with a frame fastening section and a front fastening section, where the second fastening means absorb longitudinal forces, providing an additional attachment point and allowing for the use of a standard frame that can be raised, thus eliminating the need for custom high frames, and incorporating a shorter attachment length to reduce material costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a standard frame is used without additional attachment points, then manufacturing costs are reduced and simplicity is maintained, but high leverage forces occur when handling high fronts which can cause detachment
Solution Approach 1:
The fastening attachment is divided into separate functional sections: a frame fastening section with first fastening means for attaching to the frame, and a front fastening section with second fastening means for attaching to the front. This segmentation allows the attachment to provide multiple attachment points without requiring a completely redesigned frame structure, thus improving connection reliability while maintaining relatively simple overall device complexity.
Solution Approach 2:
The fastening attachment acts as an intermediary component between the frame and the front. It includes a mounting plate that can be attached to the frame, and from which front fastening elements extend to connect to the front. This intermediary structure provides the necessary additional attachment points for high fronts without modifying the standard frame itself, resolving the contradiction between reliability and complexity.
2Adaptability or versatility
If custom high frames are produced to accommodate high fronts, then connection reliability for high fronts is improved, but manufacturing costs increase significantly
Solution Approach 1:
The fastening attachment is designed as a universal solution that can be used with standard frames while providing adaptability to high fronts. The mounting plate and front fastening elements are configured to accommodate various front heights without requiring custom frame production. This multi-functional design allows the same attachment mechanism to serve both standard and high front applications, improving adaptability while maintaining ease of manufacture.
Solution Approach 2:
Rather than investing in expensive custom high frame production, the invention uses a relatively simple, inexpensive fastening attachment that can be added to standard frames. The attachment includes basic components like a mounting plate and fastening elements that are cost-effective to manufacture. This approach trades the high cost of custom frame production for a more economical attachment solution, resolving the contradiction between adaptability and manufacturing cost.
3Stability of the object's composition
If the attachment length is extended to cover the entire frame length, then structural stability is improved, but material costs and device complexity increase
Solution Approach 1:
The fastening attachment is designed with localized fastening sections rather than continuous coverage along the entire frame length. The mounting plate provides stable attachment at specific critical locations where fastening is most needed, such as near the top edge of the frame for high fronts. This local quality approach maintains attachment stability at key positions while reducing material consumption compared to full-length attachment, resolving the contradiction between stability and material quantity.
