Solution Overview
Problem
Existing panel jig devices are inflexible and costly due to the need for specialized equipment for various vehicle models, as they cannot effectively adjust to the diverse shapes and sizes of panel restriction surfaces, leading to potential damage and increased investment for new jig devices.
Innovation Solution
A panel jig device with a motor assembly, rotary shaft, locator, clamping cylinder, and guide unit that allows for adjustable clamping angles and translational motion to accommodate different panel shapes, using an electric motor and gearbox to rotate the locator and guide unit, enabling precise alignment and clamping without damaging the panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If exclusive jig devices are used for various vehicle models, then the clamping precision for each vehicle type is improved, but the device complexity and investment cost increase
Solution Approach 1:
The patent applies universality by designing a single panel jig device that can accommodate multiple vehicle models through adjustable components. The locator assembly can be repositioned along the clamping direction, and the clamping angle can be adjusted via the operating rod and hinge joint, allowing one device to perform the clamping function for various vehicle types without requiring multiple exclusive jig devices.
Solution Approach 2:
The patent applies dynamics by making the locator assembly movable rather than fixed. The locator can translate along the clamping direction and adjust its angle through the operating rod mechanism, enabling the device to adapt dynamically to different panel positions and angles required for various vehicle models, thereby maintaining precision without increasing overall device complexity.
2Adaptability or versatility
If the clamping angle is fixed, then the device structure is simplified, but the adaptability to various panel shapes is reduced
Solution Approach 1:
The patent applies dynamics by implementing an adjustable clamping angle mechanism. The hinge joint between the operating rod and locator, combined with the operating rod's movement, enables the locator to achieve different clamping angles dynamically. This allows the device to adapt to various panel shapes and restriction surfaces without requiring multiple fixed-angle devices.
Solution Approach 2:
The patent applies segmentation by dividing the clamping mechanism into modular components: the locator assembly, operating rod, hinge joint, and clamping unit. This segmentation allows independent adjustment of each component to achieve the required clamping angle for different vehicle models, improving adaptability while keeping each individual component relatively simple.
3Object-affected harmful factors
If the clamping angle does not match the panel restriction surface angle, then the device structure is simpler, but the panel restriction surface may be damaged
Solution Approach 1:
The patent applies dynamics by making the clamping angle adjustable through the operating rod and hinge joint mechanism. This allows the clamping angle to be matched precisely to the panel restriction surface angle for each vehicle model, preventing panel damage while avoiding the need for multiple pre-configured fixed-angle devices.
Solution Approach 2:
The patent applies parameter changes by allowing the clamping angle parameter to be varied according to the specific requirements of different vehicle models and panel restriction surfaces. This ensures optimal matching between the clamping angle and panel geometry, preventing damage without requiring complex fixed-geometry devices for each case.
