Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional précising mechanisms use fixed jaws to align electronic components, then alignment can be achieved, but the components risk damage when initial orientations deviate significantly from required orientation
Solution Approach 1:
The patent applies dynamics by making the jaw orientations adjustable rather than fixed. The mechanism can dynamically adapt jaw positions to match the initial orientation of each component, allowing gentle alignment without forcing components into position. This resolves the contradiction by enabling precise alignment while minimizing damage risk through adaptive, orientation-matched jaw configuration.
Solution Approach 2:
The patent changes the parameter of jaw orientation from fixed to variable. By detecting the initial orientation of each component and相应地 adjusting jaw positions, the system optimizes the alignment process for each component's specific orientation. This parameter change allows precise alignment while reducing harmful forces that would occur with fixed jaw positions.
2Adaptability or versatility
If multiple motion steps are used to align components from various orientations, then alignment coverage is improved, but cycle time increases and throughput decreases
Solution Approach 1:
The patent applies preliminary action by detecting the initial orientation of each component before the alignment process begins. This advance knowledge allows the system to pre-position the jaws to match the component's orientation, eliminating the need for multiple trial motion steps. The component is aligned in a single efficient operation, maintaining high adaptability while improving throughput.
Solution Approach 2:
The patent implements feedback by using an inspection station to detect the initial orientation of each component and using this information to control jaw positioning. This closed-loop feedback system ensures the jaws are correctly positioned before alignment begins, allowing the mechanism to handle various orientations efficiently without requiring multiple corrective motion steps, thus maintaining high productivity.
3Manufacturing precision
If mechanical forces are applied to force components into required orientation, then alignment is achieved, but component damage risk increases
Solution Approach 1:
The patent uses dynamics to adapt jaw orientations to each component's initial state, allowing gentle guidance into the required orientation rather than forcing it. The jaws meet the component at compatible angles, reducing mechanical stress and damage risk while achieving accurate alignment through adaptive positioning rather than excessive force.
4Device complexity
If fixed jaw orientations are used in précising mechanisms, then device complexity is reduced, but the ability to handle components with varying initial orientations is limited
Solution Approach 1:
The patent applies dynamics by transitioning from fixed to adjustable jaw orientations. The mechanism incorporates actuators and control systems that allow real-time adjustment of jaw positions based on detected component orientations. This dynamic capability significantly improves adaptability to handle various initial orientations while the overall device complexity remains manageable through systematic design.
Solution Approach 2:
The patent changes the orientation parameter from fixed to variable, allowing the mechanism to adapt to different component initial orientations. This parameter change enhances versatility without excessive complexity increase, as the system uses coordinated control of multiple jaws to achieve the required adaptability through programmable position adjustment.

AI summary
For aligning an electronic component to a required orientation, the electronic component is picked up and it is inspected while it is being held to determine its initial orientation. A précising mechanism is then rotated to correspond to the initial orientation of the electronic component. After the electronic component is secured on the précising mechanism in the initial orientation, the précising mechanism is rotated to align the electronic component to the required orientation. Thereafter, the electronic component that has been aligned to the required orientation may be picked up for further testing and/or processing.
