Solution Overview
Problem
Conventional truckle structures face issues with difficult operation, material wastage, complex manufacturing, deformation, ease of damage, and poor stability due to integrated braking and releasing structures, which hinder easy operation, safety, and stability.
Innovation Solution
A double-pedal double-wheel truckle with independent braking and releasing functions, where the braking device is positioned between the rotating & locking device and the truckle body, allowing for easy operation, stable braking, and safe usage by separating the braking and releasing functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the braking structure is integrated with the releasing structure, then the device complexity is reduced, but the ease of operation deteriorates and operational stability deteriorates
Solution Approach 1:
The braking device is divided into independent braking and releasing structures. The braking structure includes a braking pedal, braking arm, and braking block, while the releasing structure includes a releasing pedal and releasing arm. This segmentation allows independent operation of braking and releasing functions, improving ease of operation and operational stability while maintaining manageable device complexity through functional separation.
2Ease of operation
If the braking device is suspended from the front end of the holding platform, then the ease of operation is improved, but the manufacturing complexity increases and material waste occurs
Solution Approach 1:
The braking device is integrated with the holding platform as a unified structure. The braking pedal is disposed on the holding platform, and the braking arm connects to the truckle body, forming an integrated assembly that reduces manufacturing steps and material waste while maintaining ease of operation through proper spatial arrangement.
3Force
If the braking device directly presses against the truckle body and pivot rotating position, then the braking force is increased, but the truckle deformation occurs
Solution Approach 1:
The braking block serves as an intermediary component between the braking arm and the truckle body. The braking arm pivots to move the braking block, which then presses against the truckle body to provide braking force. This intermediary arrangement distributes the braking force more evenly and prevents direct concentrated pressure on the pivot rotating position, reducing truckle deformation while maintaining effective braking force.

AI summary
A double-pedal double-wheel truckle with independent braking and releasing functions is a truckle for a precision instrument and comprises a body, a rotating & locking device, a truckle body device, a braking device and a bottom cover body. The body is provided for disposing a rotating & locking device, a truckle body device, a braking device and a bottom cover body. With the independent braking and releasing functions of the braking device of the body, the user can easily operate and stably block the rotating & locking device and the truckle body device. The bottom cover body is provided for preventing foreign matters from entering the truckle body device, so that the truckle can be locked from rotation. By such arrangements, it can achieve the objectives, such as easy operation, easy to distinguish braking state, stable braking, reducing noises, strengthening structure and safe usage, etc.
