Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex retaining devices are used to secure cavity wall boxes, then the securing reliability is improved, but the installation complexity increases
Solution Approach 1:
The retaining device is segmented into multiple independent retaining elements (at least two retaining elements) that can be individually deformed and positioned. Each retaining element can be independently deformed into the wall opening and secured, allowing the complex securing function to be divided into simpler, manageable steps that reduce overall installation complexity while maintaining reliability
Solution Approach 2:
The retaining elements are pre-formed with a deformable structure that allows them to be temporarily deformed into the wall opening during installation. This preliminary deformation action enables the retaining elements to be easily inserted and positioned before final securing, simplifying the installation process while ensuring reliable fixation
2Stability of the object's composition
If traditional securing mechanisms are used, then the mounting stability is improved, but the installation time increases
Solution Approach 1:
The retaining elements incorporate a deformable structure that transitions from a flexible insertion state to a rigid secured state. During installation, the retaining elements are deformed to pass through the wall opening, then return to their original shape to provide stable mounting. This dynamic behavior enables quick installation without compromising mounting stability
Solution Approach 2:
The retaining elements undergo parameter changes in their physical state during installation - transitioning from a deformed, flexible state during insertion to a rigid, stable state during securing. This parameter change allows the retaining elements to be easily installed in a deformed state and then provide stable mounting when returned to their original configuration
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
Facilitates quick and stable installation of the cavity wall box by enabling easy insertion and secure fixation to the wall, simplifying the installation process while ensuring electrical connections can be made efficiently.
Implementation Method 1
the at least one retaining element is designed to be deformable. The retaining elements can thus be deformed, at least temporarily, into the mounting contour, particularly into the groove. In an undeformed state, however, the retaining elements advantageously protrude from the clamping element
