Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional apparatus is used, then the structure is simple, but the sealing performance is poor causing laser leakage
Solution Approach 1:
The protective cover is divided into a housing and a sliding door that can move independently. The sliding door includes locking elements that engage with the housing to create sealed compartments, allowing the structure to maintain simplicity while achieving reliable sealing through modular segmentation.
Solution Approach 2:
The locking elements are nested within the sliding door and housing structures. The first locking element on the sliding door engages with the second locking element on the housing, creating a nested locking mechanism that enhances sealing without significantly increasing external complexity.
2Productivity
If conventional apparatus is used, then the device is easy to operate, but the detection efficiency is low
Solution Approach 1:
The sliding door can be dynamically opened and closed to create separate inspection spaces. This dynamic configuration allows simultaneous inspection of multiple objects by different operators on opposite sides, significantly improving detection efficiency while maintaining ease of operation through simple sliding motion.
Solution Approach 2:
The sliding door mechanism transforms the inspection space from a single-dimensional sequence to a two-dimensional parallel arrangement. Operators can simultaneously inspect objects on both sides of the apparatus, converting sequential inspection into parallel processing and thereby doubling the detection efficiency.
3Object-affected harmful factors
If the sliding door is made light-tight, then laser safety is improved, but the material selection becomes more restricted
Solution Approach 1:
The sliding door and housing are constructed from composite materials that combine light-tight properties with mechanical strength. This allows the structure to effectively block laser radiation while maintaining ease of manufacture through the use of engineered composite materials that integrate multiple functional requirements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents laser leakage, improving safety and detection efficiency by allowing simultaneous inspection and handling of objects on both sides, reducing the risk of laser exposure and enhancing operational efficiency.
Implementation Method 1
the housing is provided with an elastic element, wherein, the elastic element is compressed by the sliding door when the closed space formed by the sliding door and the housing is closed; and, when the first locking element is disengaged and unlocked from the second locking element, the sliding door slides under the action of a restoring force of the elastic element, to open the closed space
Implementation Method 2
locking/unlocking between the first locking element and the second locking element is achieved by means of an electromagnetic force
