Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If standardized espagnolette fittings are used, then production is simplified, but functionality is limited and adaptability to different sizes is poor
Solution Approach 1:
The fitting system is divided into separate functional modules: bearing units for positioning, locking units for security, and opener/closer units for automation. Each module can be independently selected and combined to create customized fitting systems for different window and door applications, maintaining production simplicity while enabling functional versatility.
Solution Approach 2:
The patent creates universal fitting components that can serve multiple functions. For example, bearing units can operate in different configurations to enable various sash positions (closed, tilted, open), and the modular design allows the same basic components to be adapted across different building element sizes and types, achieving both manufacturing efficiency and functional adaptability.
2Adaptability or versatility
If espagnolette fittings are customized for different sizes and designs, then adaptability is improved, but production complexity and assembly difficulty increase
Solution Approach 1:
By segmenting the fitting system into standardized modular components (bearing units, locking units, opener/closer units), the patent enables customization for different sizes and designs through simple selection and combination of modules rather than custom manufacturing, thereby reducing production complexity while maintaining adaptability.
Solution Approach 2:
The modular components are designed with adjustable parameters and configurable arrangements that can be adapted to different building element sizes and designs without changing the fundamental component structure, allowing versatility through parameter variation rather than complex custom design.
3Device complexity
If manual operation with control elements is used, then device complexity is reduced, but automation functionality is limited
Solution Approach 1:
The fitting system separates manual control functions from automated drive functions into distinct modules. Opener/closer units with integrated drives can be selectively incorporated to provide automatic sash adjustment, while bearing and locking units remain mechanically simple, allowing the system to achieve automation capability without unnecessarily increasing overall device complexity.
4Reliability
If espagnolette fittings require careful installation and maintenance, then reliability is improved, but ease of operation and maintenance burden increase
Solution Approach 1:
By dividing the fitting system into modular functional units, the patent enables simpler installation through standardized connection interfaces and reduces maintenance burden by allowing individual module replacement or servicing without affecting the entire fitting system, thereby improving ease of operation while maintaining reliability.

AI summary
The invention relates to a fitting system for a construction element, which has a frame and a movable wing, which fitting system is designed to shift the wing between at least two different functional states and comprises a set of modular functional units. The set comprises two bearing units for rotatably mounting the wing on the frame, each bearing unit comprising a first bearing part designed for fastening to the frame and a second bearing part designed for fastening to the wing, the second bearing part being movable relative to the first bearing part transversely to the plane of the frame by means of a drive in the assembled state, at least one locking unit for releasably fixing the wing to the frame, which locking unit has a locking element that can be moved between a fixing position and a release position by means of a drive, and optionally at least one opening/closing unit for automatically opening and closing the wing, which opening/closing unit has a control element, which is provided for acting on the wing or on the frame and which can be moved between a retracted position and an extended position by means of a drive.
