Pull Back Vehicle Path Switching via Clutch Gear Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pull back vehicles are limited to traveling in a straight line or an S-line and cannot switch paths easily, making the playing experience monotonous and lacking in interest.
Innovation Solution
A pull back vehicle chassis with a driving gear box, steering assembly, and clutch assembly that allows for switching between straight-line and S-line travel by transmitting driving force to the steering gear and assembly through a gear set, enabling the vehicle to change paths by disengaging the clutch, allowing the vehicle to travel in an S-shaped path or straight line.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sets of transmission equipment are used to enable switching between straight line and S-line travel, then the vehicle can switch travelling lines, but the device complexity and cost increase
Solution Approach 1:
The patent applies a single multi-functional transmission mechanism that can achieve both straight-line travel and S-line travel by varying the engagement state of the clutch assembly. The same gear set and steering assembly serve dual purposes: when the clutch is engaged, it enables S-line travel through the steering gear; when disengaged, it allows straight-line travel. This eliminates the need for separate transmission equipment for each travel mode.
Solution Approach 2:
The patent introduces a dynamic clutch assembly that can be engaged or disengaged during operation to switch between different travelling lines. The clutch assembly dynamically connects or disconnects the driving gear from the steering gear, allowing the vehicle to transition between S-line and straight-line travel modes without requiring multiple fixed transmission paths.
2Adaptability or versatility
If a clutch assembly is added to enable path switching, then the vehicle can switch between straight and S-shaped paths, but the device complexity increases
Solution Approach 1:
The patent merges the clutch assembly with the existing steering gear and driving gear structure. The clutch assembly is integrated into the transmission path already present in the vehicle, combining the path switching function with the existing gear mechanisms rather than adding a completely separate system. This reduces overall complexity compared to having independent switching mechanisms.
Solution Approach 2:
The clutch assembly acts as an intermediary element between the driving gear and the steering gear. It mediates the power transmission by selectively connecting or disconnecting these components, enabling path switching without requiring direct mechanical linkages for both modes. This intermediary approach simplifies the control mechanism while achieving the desired functionality.
