Multipurpose Holding Apparatus Locking Mechanism
Solution Overview
Problem
Existing bicycle carriers require complex and uncomfortable manipulation of multiple locking units to secure bicycles and other equipment, making the loading and unloading process cumbersome.
Innovation Solution
A holding apparatus featuring a rotation bar with an insertion groove and screw thread, a clamp with a screw groove, and a grip member with protrusions and a locking lever, allowing for interlocking of holders and preventing separation, thus simplifying the locking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple locking units are provided in the holder to secure the bicycle and equipment to the carrier, then the reliability of fixation is improved, but the device complexity and ease of operation deteriorate due to the need to manipulate multiple locking units
Solution Approach 1:
The patent combines multiple locking units into a single integrated locking mechanism. The holder includes a locking unit with a locking protrusion that engages with a locking groove on the carrier, and another locking protrusion that engages with a locking groove on the equipment. This single locking unit simultaneously secures both the bicycle and equipment to the carrier, eliminating the need for multiple separate locking units and simplifying the overall locking mechanism while maintaining reliable fixation.
Solution Approach 2:
The locking unit is designed with multi-functionality to perform multiple locking tasks. The same locking protrusion that secures the holder to the carrier also secures the equipment to the holder. This universal locking mechanism can lock both the bicycle frame and the equipment in a single operation, reducing complexity while ensuring reliable fixation of multiple components.
2Reliability
If multiple locking units are provided to secure the bicycle and equipment, then the fixation reliability is improved, but the ease of operation deteriorates due to cumbersome manipulation
Solution Approach 1:
The patent merges multiple locking operations into a single action. The locking unit includes a locking protrusion that simultaneously engages with locking grooves on both the carrier and the equipment when the holder is installed. This allows the user to secure both the bicycle and equipment in one simple motion, dramatically improving ease of operation while maintaining reliable fixation through the engaged locking protrusions.
3Adaptability or versatility
If independent locking units are provided for the bicycle and equipment portions of the holder, then the adaptability is improved, but the device complexity increases due to separate manipulation requirements
Solution Approach 1:
The locking unit is designed with universal functionality to adapt to different locking scenarios. The same locking protrusion can engage with locking grooves on the carrier, on the equipment, or both simultaneously. This multi-functional design provides adaptability for securing various types of equipment while maintaining a simple, unified locking mechanism rather than requiring separate specialized locking units for each scenario.

AI summary
A holding apparatus for multipurpose may include a rotation bar having an insertion groove formed at one end portion thereof, the insertion groove having a screw thread formed thereon, and a plurality of catching protrusions formed at the another end portion thereof along an outer circumference, a clamp having a screw groove, engaged with the screw thread, which is formed at an end portion side of the clamp which is separated or engaged with the screw thread of the rotation bar and preventing the separation by an end portion inserted into the insertion groove along a rotation axis of the rotation bar, and a grip member provided to another end portion of the rotation bar, including a fastening apparatus to be fastened to a target object, and preventing rotation of the rotation bar by being caught and coupled to the catching protrusions upon locking the fastening apparatus.
