Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ratchet mechanisms are complex and costly to assemble, and they often fail to sustain high torque without breaking the teeth portions.
Innovation Solution
A ratchet connector design featuring a first body with a semi-circular trough and a control ring that allows for easy assembly and directional control, using a resilient unit and ring teeth portion to engage with the ratchet teeth, enabling unidirectional movement without breaking the teeth, and allowing for quick assembly using a screw or C-shaped ring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional ratchet mechanism with multiple components is used, then the ratchet can achieve directional control, but the structure becomes complicated and manufacturing costs increase
Solution Approach 1:
The patent merges multiple conventional ratchet components into an integrated ratchet connector structure. The first body, second body, control ring, and ratchet are combined into a single unified component that achieves directional control without requiring separate stopping blocks, multiple plugs, or complex adjusting mechanisms. This integration maintains the ratchet's directional control function while significantly reducing component count and assembly complexity.
Solution Approach 2:
The ratchet connector is designed as a multi-functional component that simultaneously provides directional control, torque transmission, and structural support. The control ring integrates both the control function and the structural housing, while the ratchet teeth portion serves both engagement and directional control purposes. This multi-functionality eliminates the need for separate specialized components found in conventional designs.
2Reliability
If a conventional ratchet mechanism with a stopping block is used, then directional control is achieved, but the teeth portion may break when sustaining larger torque
Solution Approach 1:
The control function and structural support are merged into the control ring and ratchet connector bodies, eliminating the separate stopping block that was prone to failure. The integrated structure distributes torque more effectively across the entire connector rather than concentrating stress on a small stopping block, thereby preventing tooth breakage while maintaining directional control.
Solution Approach 2:
The ratchet connector employs a robust integrated structure with reinforced teeth portions designed to withstand high torque loads. The unified construction allows for optimized material distribution and stress flow paths that prevent the localized failure modes seen in conventional stopping block designs, enabling sustained high torque application without tooth breakage.
3Reliability
If a conventional ratchet mechanism with multiple components is used, then directional control is achieved, but assembly time and manufacturing costs increase
Solution Approach 1:
By integrating multiple conventional components into a single ratchet connector unit, the assembly process is dramatically simplified. The unified structure requires fewer assembly steps, fewer fasteners, and less alignment work compared to assembling separate bodies, stopping blocks, plugs, and adjusting rings. This directly increases assembly speed and manufacturing productivity while preserving directional control functionality.
Solution Approach 2:
The ratchet connector is designed as a modular integrated component that can be manufactured as a single piece or in few segments, facilitating rapid assembly. The control ring and connector bodies are structured to enable quick attachment and detachment, and the patent alternatively allows for a C-shaped ring configuration that enables even faster assembly by simply snapping into place without requiring threaded fasteners.
4Reliability
If a conventional ratchet mechanism with complex structure is used, then directional control is achieved, but manufacturing costs significantly increase
Solution Approach 1:
The integration of multiple functions into a single ratchet connector reduces manufacturing costs by eliminating the need to produce, inventory, and assemble multiple separate components. The unified structure requires fewer machining operations, fewer material purchases, and less quality inspection across multiple parts, directly reducing manufacturing costs while maintaining directional control capability.
Solution Approach 2:
The multi-functional design allows a single component to replace several specialized parts, reducing overall manufacturing complexity and cost. The control ring and connector bodies perform multiple functions simultaneously, eliminating the need for separate stopping blocks, plugs, and adjusting mechanisms, thereby simplifying the supply chain and reducing per-unit manufacturing costs.

AI summary
A ratchet connector may include a first body, a ratchet, a control ring and a second body. The first body has a cylinder at one end and a semi-circular trough formed at an outer surface of the cylinder and a through hole at the semi-circular trough. The ratchet has a teeth portion on both sides of an arc surface thereof, a sliding surface formed between two teeth portions, a shaft rod configured to be insert into the through hole to enable the ratchet to be pivotally disposed in the semi-circular trough. The control ring having a fixed trough and a switching trough and the control ring disposed onto the cylinder of the first body to enable the switching trough to be disposed against the ball; and the second body having a receiving space and a ring teeth portion is formed inside the receiving space.
