Kart Frame Telescopic Locking Mechanism for User Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing kart chassis designs with telescopic locking structures fail to consistently secure the front and rear frames for users of different strengths, leading to potential injuries during use or collisions.
Innovation Solution
A kart frame design featuring a first frame with an outer sleeve and a second frame with inner perforations, along with a second fixing piece that includes a rod section and fitting section, allowing for adjustable fitting and enhanced structural reliability and user safety by preventing sudden expansion or contraction of the frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a telescopic locking structure with a collar is used to allow frame adjustment for different body shapes, then the adaptability to different users is improved, but the reliability of the locking mechanism deteriorates because the locking force varies with user strength
Solution Approach 1:
The locking structure uses the user's own body parts (hand, arm, or leg) as the locking component. The user inserts their body part through the passage in the collar to lock or unlock the telescopic structure. This eliminates the need for separate locking mechanisms while ensuring that the locking force is naturally applied by the user's own strength, and the structure can be operated by anyone regardless of strength level due to the simple body-insertion mechanism.
Solution Approach 2:
The collar with a passage acts as an intermediary between the user's body and the telescopic locking structure. By inserting a body part through the passage, the user's body serves as the mediating element that engages the locking mechanism. This intermediary design allows the structure to be locked or unlocked simply by the presence and movement of the user's body part, making it both reliable and accessible to all users.
2Device complexity
If a simple collar-based locking structure is used, then the device complexity is reduced, but the safety deteriorates because the front and rear frames may suddenly shorten during use or collision
Solution Approach 1:
The user's body part inserted through the collar passage serves as both the operating mechanism and the safety engagement component. The body part physically blocks the passage, preventing the collar from rotating or disengaging during normal use or collision. This simple yet effective design eliminates complex locking components while ensuring safety through the user's own body acting as the retention element.
Solution Approach 2:
The collar structure is designed with a passage that, when blocked by the user's body part, provides beforehand protection against sudden frame shortening. The body part pre-engages the locking position, and the collar's geometry ensures that even during collision, the framed structure cannot suddenly contract because the passage remains blocked by the user's body, providing prior cushioning against harmful movement.
