Bike Carrier Plunger Depth Marking for Faster Reassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of bike carriers is time-consuming and labor-intensive due to the varying positions of through holes in different trailer bars, requiring repeated adjustments of the plunger and trailer bar to match their holes.
Innovation Solution
A plugging position recording device with a sliding track and adjustable recording unit is integrated into the bike carrier's plunger, allowing the recording unit to be abutted against the trailer bar's end face during initial insertion, enabling quick reconnection by aligning corresponding holes when reassembling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the plunger and trailer bar are manually adjusted repeatedly to match through holes during assembly, then the bike carrier can be connected to the car, but the assembly process becomes time-consuming and labor-intensive
Solution Approach 1:
The patent applies the preliminary action principle by pre-marking the correct insertion depth position on the plunger before the actual assembly process. This pre-marked position guide allows the user to directly insert the plunger to the correct depth without repeated adjustments and trial-and-error, thereby significantly reducing assembly time and effort while maintaining ease of operation
Solution Approach 2:
The patent uses the copying principle by creating a visual mark (copy of the correct position) on the plunger that replicates the ideal insertion depth information. This mark serves as a simplified copy of the correct assembly state, allowing users to quickly identify and achieve the proper positioning without needing to perform repeated manual adjustments
2Adaptability or versatility
If the bike carrier is designed with large volume and weight to provide adequate carrying capacity, then it can effectively carry bikes, but it becomes tiring and time-consuming for users to assemble
Solution Approach 1:
The patent reduces assembly difficulty for this heavy-duty carrier by pre-marking the correct insertion depth on the plunger. This preliminary positioning guide compensates for the carrier's large size and weight by providing clear assembly guidance, making the assembly process easier despite the carrier's substantial carrying capacity

AI summary
A plugging position recording device is provided to be configured to be applied to a plunger of a bike carrier, and the plugging position recording device includes a sliding track and a recording unit. The sliding track is disposed on the plunger. The recording unit is positionably received and adjustable within the sliding track, and the recording unit is abutted against an end face of a trailer bar to mark a depth of the plunger inserted into the trailer bar.
