Compensation Nut Locking Mechanism for Vibration Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compensation nuts used in the motor industry face issues with maintaining a locked position during transport and installation, leading to productivity losses due to separation of nut and bolt components under vibrations and shocks, and existing solutions complicate the manufacturing process or interfere with threads.
Innovation Solution
A metal compensation nut design featuring a bolt with mechanical stops and a braking arm that engages with a flange, allowing for a simple and cost-effective manufacturing process while preventing displacement without affecting the threads, ensuring the nut remains locked during transport and installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If locking devices with plastic stops or additional pieces are used to prevent nut-bolt separation, then the locking reliability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The locking function is merged with the existing nut and bolt components. The braking arm is integrated into the nut structure, and the mechanical stops are incorporated into the bolt design, eliminating the need for separate locking components while maintaining reliable vibration resistance
Solution Approach 2:
The locking function is extracted from complex plastic stops and additional locking pieces, and instead implemented through simple mechanical features (braking arm and stops) that are taken out as minimal necessary elements integrated into the basic component structure
2Reliability
If complex locking mechanisms are added to prevent displacement, then the locking reliability is improved, but the manufacturing process becomes more complex and costly
Solution Approach 1:
The locking function is merged with the existing nut and bolt components. The braking arm is integrated into the nut structure, and the mechanical stops are incorporated into the bolt design, eliminating the need for separate locking components while maintaining reliable vibration resistance
Solution Approach 2:
Instead of using expensive plastic stops or complex locking mechanisms, the invention uses simple, inexpensive mechanical features (metal braking arm and stops) that can be easily manufactured and replaced if necessary, reducing both material and manufacturing costs
3Reliability
If additional locking pieces are used to block thread rotation, then the prevention of accidental undoing is improved, but the device complexity increases
Solution Approach 1:
The thread protection function is extracted from complex locking pieces and instead implemented through the simple mechanical stop-braking arm interaction that blocks rotation at the source without interfering with the thread structure itself
Solution Approach 2:
The mechanical stops and braking arm act as intermediaries between the bolt and nut, providing a mechanical barrier that prevents accidental undoing without directly interfering with the threaded connection, allowing the thread to remain accessible and functional

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively maintains the compensation nut in a locked position during transport and installation, reducing the need for operator assembly and preventing accidental undoing, while being easy to manufacture and free from complex components that interfere with threads.
Implementation Method 1
Said nut also includes a braking arm which provides an area of movement in which the flange mentioned is engaged
Implementation Method 2
The arm has one extremity with a stop and has resilience deriving from its constructed shape
