Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional windshield wiper assembly is used, then the wiper can function to wipe the windshield, but the assembly is difficult to couple to the driving arm
Solution Approach 1:
The wiper assembly is divided into separate components: a wiper blade, a wiper arm, and a coupling mechanism with distinct parts including a coupling member with a coupling hole and a driving arm with a coupling protrusion. This segmentation allows each part to be independently designed and assembled, simplifying the overall coupling process
Solution Approach 2:
A coupling member acts as an intermediary between the wiper arm and the driving arm. The coupling member features a coupling hole that receives the coupling protrusion from the driving arm, providing a simple mediating mechanism that enables easy attachment without complex fastening procedures
2Productivity
If the wiper assembly is designed for easy coupling, then assembly efficiency improves, but the structural complexity increases
Solution Approach 1:
The assembly is segmented into modular components (wiper blade, wiper arm, coupling member) that can be independently manufactured and assembled. This modular approach enables rapid assembly by simply connecting the coupling protrusion to the coupling hole, significantly improving assembly efficiency while keeping each component structurally simple
Solution Approach 2:
The coupling mechanism is designed to be self-assembling through the natural insertion of the coupling protrusion into the coupling hole. The geometry of these components guides them into proper alignment and connection without requiring additional fastening steps or complex assembly procedures, enabling users to assemble the wiper themselves quickly
