Solution Overview

Problem

Conventional rotating buffer stations for chips are inflexible and require replacement when handling differently-sized chips, lacking the ability to adapt to various sizes without an alignment device.

Innovation Solution

A rotating buffer station with a disk-shaped upper cover plate, rotatable plate, movable jaw members, and a lower base, where the rotatable plate's cam slots and guide slots allow the jaw members to radially adjust, forming a socket that can be resized to accommodate various chip sizes, with a locking mechanism to secure the size and a driving member for manual or electric operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the chip socket size is fixed in conventional rotating stations, then the structure is simple and manufacturing is easy, but the device cannot adapt to differently-sized chips requiring complete jig replacement

Engineering Contradiction:
Improveadaptability to differently-sized chipsVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the chip socket size adjustable through a rotatable plate mechanism. The movable jaw members can be positioned at different locations along the guide slots by rotating the rotatable plate, allowing the chip socket to dynamically adapt to different chip sizes. This transforms the static, fixed-size socket into a dynamic, adjustable structure that maintains versatility while keeping the overall mechanism relatively simple.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements universality by designing a single rotating station that can accommodate multiple chip sizes through the adjustable jaw members. Instead of requiring separate jigs for different chip sizes, one universal rotating station with adjustable parameters can handle various chip dimensions, thereby improving adaptability without proportionally increasing device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Measurement precision

If a laser alignment device is added to detect chip orientation, then measurement precision is improved, but device complexity and cost increase

Engineering Contradiction:
Improvechip orientation detection accuracyVSAvoidalignment device complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies the self-service principle by designing the rotating station to inherently provide alignment guidance through its mechanical structure. The guide slots and cam slots work together to automatically guide the jaw members into the correct positions and orientations, eliminating the need for external laser alignment devices. The system serves its own alignment function through its geometric design, thereby maintaining measurement capability while reducing device complexity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent uses the cam slot as an intermediary element that translates the rotation of the rotatable plate into precise radial movement of the jaw members. This mechanical intermediary ensures accurate chip orientation and positioning through pure mechanical means, replacing the need for complex optical alignment systems while maintaining measurement precision.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If the entire jig is replaced for differently-sized chips, then measurement precision and orientation accuracy are maintained, but loss of time and productivity decrease

Engineering Contradiction:
Improvechip orientation accuracyVSAvoidprocess shifting efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent applies dynamics by enabling continuous adjustment of the chip socket parameters within a single jig through the rotatable plate mechanism. Instead of discrete jig replacements, the system allows dynamic reconfiguration by rotating the plate to different angular positions, which continuously adjusts the jaw member positions. This eliminates downtime associated with physical jig changes while maintaining orientation accuracy, thereby improving productivity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements preliminary action by pre-designing the guide slots and cam slots in specific geometric patterns that anticipate different chip size requirements. The slots are configured in advance to guide the jaw members to appropriate positions for various chip dimensions, allowing quick adaptation without time-consuming adjustments or replacements, thus maintaining both precision and productivity.

Inventive Principle:
Principle #10Preliminary action

AI summary

A rotating buffer station for a chip mainly comprises an upper cover plate, a rotatable plate, a movable jaw member and a lower base. The upper cover plate is arranged on the lower base and formed with a guide slot. The rotatable plate is located between the lower base and the upper cover plate and formed with a cam slot. The rotatable plate is pivotally coupled to the lower base. The movable jaw member is slidably engaged with the cam slot and the guide slot. When the rotatable plate is rotated, the cam slot forces the movable jaw member to move radially along the guide slot so as to form a chip socket. Accordingly, with rotation of the rotatable plate, the cam slot forces the movable jaw member to move radially along the guide slot so that the chip socket can be resized to hold various differently-sized chips.
