Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for assembling the lockup mechanism between a vehicle's shift cable and engine transmission are inefficient and prone to errors due to the use of open mouth pliers, which can lead to poor assembly quality, safety issues, and operational challenges in tight spaces.
Innovation Solution
A mounting device with a pliers body, positioning member, push rod, and handle system that allows for stable positioning and easy bending of the lockup piece, ensuring secure mounting without the need for extensive space and minimizing the risk of tool drop, featuring a positioning groove, guide sleeve, and reset spring for improved stability and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If open mouth pliers are used to bend the lockup piece, then the bending operation can be performed, but the operation is difficult in small spaces and there is a risk of tool drop causing damage
Solution Approach 1:
The device segments the bending operation into distinct functional components: the positioning member with barb portion for gripping the lockup piece, the push rod for applying bending force, and the handle for actuation. This segmentation allows each component to be optimized for its specific function while working together in a compact configuration that eliminates the need for large-space pliers.
Solution Approach 2:
The mounting device acts as an intermediary tool between the operator and the lockup piece. Instead of directly manipulating the lockup piece with pliers, the operator uses the handle to actuate the push rod, which then applies the bending force through the positioning member. This intermediary mechanism provides controlled, precise bending while preventing tool drop and improving operational reliability.
2Productivity
If open mouth pliers are used to grasp and press the lockup piece, then bending can be achieved, but the process requires tight grasping and continuous force application which reduces operation efficiency
Solution Approach 1:
The positioning member with its barb portion is designed to self-grip the lockup piece once positioned, eliminating the need for continuous operator intervention to maintain grasping force. The push rod automatically applies bending force when the handle is actuated, and the mechanism maintains the bent position without requiring continuous force application. This self-service characteristic significantly improves operation efficiency and comfort.
Solution Approach 2:
The positioning member is pre-configured with the barb portion oriented to engage the lockup piece before the bending operation begins. The handle is positioned ready for actuation, and the push rod is pre-aligned to apply force at the correct location. This preliminary preparation eliminates the need for continuous adjustment and force application during the operation, improving both efficiency and ease of use.
3Manufacturing precision
If the lockup piece is bent to tightly abut on the locking nut, then a stable connection is achieved, but the process using open mouth pliers is affected by manufacturing conditions and structural design issues
Solution Approach 1:
The positioning member features a localized barb portion with specific geometric characteristics designed to engage the lockup piece at a precise location. The barb's shape and orientation are optimized for this specific engagement point, providing reliable positioning and bending without requiring complex overall device structure. This local quality approach achieves high manufacturing precision while keeping the device relatively simple.
Solution Approach 2:
The mounting device serves as a precision intermediary mechanism that translates simple handle actuation into controlled bending motion. The push rod acts as a mechanical intermediary that delivers precise force application, while the positioning member provides the final precision engagement with the lockup piece. This intermediary system achieves high locking precision without requiring the operator to directly manipulate the components with complex manual dexterity.
4Ease of manufacture
If open mouth pliers are used for the bending process, then the lockup piece can be bent, but the pliers may be accidentally dropped causing damage to the shift cable and engine transmission
Solution Approach 1:
The mounting device merges multiple functions into a single integrated tool: the positioning member for gripping, the push rod for bending, and the handle for actuation are all combined into one device. This unified structure eliminates the risk of tool drop associated with separate pliers, as the entire bending mechanism is contained within the mounted device. The integrated design maintains assembly simplicity while eliminating the harmful factor of tool drop.
Solution Approach 2:
The mounting device acts as a secure intermediary mechanism that is mounted in place during the bending operation. Rather than holding pliers in the hand, the device is mounted to provide a stable base, and the bending operation is performed through the mounted structure. This intermediary mounting approach completely eliminates the risk of tool drop, as the tool is fixed in position rather than being manually held.
