Master Link Rod Assembly Orientating Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional master link rod assemblies for wiper systems in off-road vehicles face challenges in accurate assembly due to the risk of losing pre-adjusted orientation during screw tightening, especially in constrained engine compartments, leading to improper assembly and increased time consumption.
Innovation Solution
The master link rod assembly incorporates a male and female orientating component with variable width and cone-like shapes, forming a tight fit engagement to ensure precise spatial orientation, allowing for efficient and reliable assembly in confined spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional triangular opening markings are used for spatial orientation, then the assembly process can be initiated, but the pre-adjusted orientation is easily lost during screw tightening
Solution Approach 1:
The patent applies preliminary action by pre-assembling the master link rod members with pre-adjusted spatial orientation before final installation. The orientating components (protrusion and recess) are designed to maintain this pre-adjusted orientation during the assembly process, ensuring that the precise spatial relationship is preserved when screws are tightened.
Solution Approach 2:
The orientating components act as intermediaries between the master link rod members. The protrusion on one member fits into the recess on the other member, serving as a mechanical mediator that enforces and maintains the correct spatial orientation. This intermediary mechanism prevents loss of orientation during tightening by providing continuous geometric constraint.
2Manufacturing precision
If the assembler needs to access the master link rod assembly for mounting and adjusting, then proper assembly can be achieved, but the constrained engine compartment space seriously obstructs access
Solution Approach 1:
The master link rod members are pre-assembled with correct spatial orientation in a more accessible environment before being installed in the constrained engine compartment. This preliminary assembly action transfers the complex orientation adjustment to a setting where the assembler has better access, while the orientating components ensure the pre-adjusted orientation is maintained during final installation.
3Measurement precision
If the master link rod members are pre-adjusted with markings for spatial orientation, then the correct position can be identified, but the risk of improper assembling increases due to easy loss of orientation
Solution Approach 1:
The orientating components serve as reliable intermediaries that mechanically enforce correct spatial positioning. The protrusion-recess interface acts as a physical guide that prevents improper assembly, eliminating reliance on markings that can be lost or misinterpreted. This intermediary mechanism provides continuous geometric constraint throughout the assembly process.
Solution Approach 2:
The orientating components enable self-service assembly by providing built-in geometric guidance that automatically ensures correct spatial orientation. The protrusion and recess are designed to fit together in only the correct orientation, allowing the assembly to self-align and self-verify without requiring external marking systems or complex adjustment procedures.
4Productivity
If conventional assembly procedures are used in constrained spaces, then the assembly can be completed, but the time consumption increases significantly
Solution Approach 1:
By performing the complex spatial orientation adjustment as a preliminary action during pre-assembly in a accessible environment, the time-consuming orientation work is done before constrained space installation. The orientating components then ensure this pre-adjusted orientation is maintained automatically during final installation, significantly reducing the time required in the constrained engine compartment.
Solution Approach 2:
The orientating components provide self-service by automatically maintaining correct spatial orientation throughout the assembly process without requiring continuous assembler intervention for adjustment. The protrusion-recess mechanism self-enforces the correct geometry, eliminating time-consuming manual alignment and verification steps during final installation.
