Rotating Locking Element for Universal Luggage Package Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding devices for packaging on two-wheelers, such as bicycles and motorcycles, lack a simple, robust, and cost-effective solution for detachable attachment and universal compatibility with various packaging materials.
Innovation Solution
A holding device with a fastening section and a receiving section along a longitudinal axis, featuring a locking element that can be rotated or pivoted for secure and release positions, and a tensioning device for pretensioning, along with guide shafts and bolts for locking, allowing for easy attachment and removal of packaging on a luggage rack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a holding device is designed to be simple and robust with universal compatibility, then ease of manufacture and adaptability improve, but the complexity of ensuring secure fastening for various packaging materials increases
Solution Approach 1:
The holding device is divided into distinct functional segments: a receiving section with a cross-section adapted to packaging openings, and a locking element that can rotate between locked and unlocked positions. This segmentation allows each part to be optimized independently for manufacturing simplicity while ensuring reliable fastening through their coordinated interaction.
Solution Approach 2:
The receiving section is designed with a circumferential cross-section that universally fits various packaging materials by adapting to different opening shapes. The locking element provides a universal locking mechanism that works with different packaging types, enabling one device to securely fasten diverse packaging without requiring multiple specialized designs.
2Ease of operation
If a locking element is made rotatable or pivotable for easy release, then ease of operation improves, but the device complexity increases
Solution Approach 1:
Instead of using a complex mechanism to lock the packaging in place and requiring force to release it, the design inverts the approach: the locking element naturally remains in a locked position through its rotational design, and release is achieved by simply rotating it to an unlocked position where it naturally disengages. This simplifies the release mechanism while maintaining secure fastening.
3Reliability
If a tensioning device is added for pretensioning, then the secure fastening improves, but the device complexity and manufacturing cost increase
Solution Approach 1:
The tensioning device applies pretensioning force to the locking element before the packaging is fully inserted or before the locking element is rotated into the locked position. This preliminary action ensures that when the packaging is secured, it is held firmly in place, improving the reliability of the fastening without requiring additional complex mechanisms during the final locking action.
