Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high precision machining is used to construct semiconductor handler components, then manufacturing precision is improved, but manufacturing cost increases
Solution Approach 1:
The patent implements a tip adjustment mechanism that allows the tip position to be dynamically adjusted after assembly. This dynamic adjustment capability compensates for dimensional deviations in components, enabling the use of lower precision components while maintaining overall system precision. The tip can be moved along the tip receiver to achieve proper alignment with parts.
Solution Approach 2:
The patent changes the position parameter of the tip relative to the tip receiver through an adjustment mechanism. By allowing the tip position to vary, the system can compensate for manufacturing tolerances in other components. The tip adjustment apparatus enables parameter changes that correct alignment issues without requiring high precision machining of all components.
2Ease of manufacture
If low tolerance components are used to reduce manufacturing cost, then manufacturing precision deteriorates, but device complexity increases due to adjustment mechanisms
Solution Approach 1:
The patent divides the tip assembly into separate components: a tip receiver and an adjustable tip. This segmentation allows the tip to be independently adjusted relative to the tip receiver, compensating for tolerances in either component. The separation enables lower precision machining of individual parts while maintaining overall alignment through the adjustable connection.
Solution Approach 2:
The tip adjustment mechanism acts as an intermediary between the tip receiver and the tip. This intermediary element absorbs and compensates for dimensional deviations, allowing both the tip receiver and tip to be manufactured with relaxed tolerances while still achieving proper alignment through the mediating adjustment mechanism.
3Reliability
If high precision machining is applied to all components, then misalignment is reduced, but productivity decreases due to increased manufacturing time and cost
Solution Approach 1:
The patent incorporates a tip adjustment mechanism that allows for preliminary positioning and alignment of the tip relative to the tip receiver. This preliminary action enables components to be assembled with relaxed tolerances, then adjusted to achieve proper alignment, thereby improving manufacturing efficiency without sacrificing alignment accuracy.
