Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the guide rail is designed with different versions for different locations, then the connection elements can be properly aligned with energy sources, but the production becomes complicated and assembly becomes difficult
Solution Approach 1:
The guide rail is designed with a universal mounting unit that can accommodate different door configurations (DIN left stop, DIN right stop, hinge side, opposite hinge side) without requiring different versions. The mounting unit includes adjustable connection elements that can be positioned to align with energy sources regardless of the specific installation location, thereby maintaining reliability while eliminating production complexity.
Solution Approach 2:
The mounting unit incorporates adjustable and reconfigurable components that can be dynamically positioned during installation. The connection elements can be moved or reoriented to match different energy source positions, allowing the same guide rail design to adapt to various locations without requiring multiple specialized versions.
2Reliability
If the guide rail is designed with different versions for different locations, then the connection elements can be properly aligned with energy sources, but the installation becomes less flexible
Solution Approach 1:
The mounting unit is designed as a universal component that can be installed on any door configuration (left stop, right stop, hinge side, opposite hinge side). It maintains reliable connection element alignment through its adjustable design while providing installation flexibility by accommodating all standard door types with a single guide rail version.
Solution Approach 2:
The mounting unit is divided into separate, independently adjustable components. The connection elements are segmented from the main body, allowing them to be positioned and aligned independently according to the specific installation requirements, thereby maintaining alignment reliability while enhancing installation versatility.
3Loss of information
If the guide rail uses a cable for transmission means, then power and data can be routed between door leaf and frame, but the cable may become congested when sliding element moves
Solution Approach 1:
A gear mechanism is introduced as an intermediary component between the sliding element and the cable. The gear acts as a mediator that manages cable routing and prevents congestion by coordinating cable movement with the sliding element's position, ensuring continuous power and data transmission without requiring complex cable management systems.
Solution Approach 2:
The gear mechanism preliminarily manages the cable routing before the sliding element moves. By pre-positioning and guiding the cable through the gear mechanism, the system prevents cable congestion in advance, ensuring smooth power and data transmission throughout the sliding element's range of motion.
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 guide rail is simple to produce, easy to assemble, and universally applicable, providing flexible and inexpensive installation on differently configured door leaves or frames, ensuring reliable operation and protection of the transmission means.
Implementation Method 1
The sliding element can advantageously slide in the guide rail almost without friction. The sliding element thus serves to at least partially support the movement of the door leaf between the open position and the closed position.
Implementation Method 2
a spring element can be provided in order to accumulate closing energy during the movement of the door leaf from the closed position into the open position, which energy is lost during the movement of the door leaf back into the closed position can be released again at least partially.

AI summary
The invention relates to a guide rail (100) for guiding a door leaf (101) between an open position (III) and a closed position (I) with respect to a door opening (104) in a door frame (102), comprising: at least one guide section (1) with a guide chamber (10) in which a sliding element (11) is movably received, wherein the guide section (1) has a guide opening (13) through which a bearing axis (14) of the sliding element (11) at least partially extends from the guide chamber (10), on which a lever element (15) is rotatably mounted to establish an operative connection between the sliding element (11) and the door leaf (101); at least one functional section (2) with a functional chamber (20) in which a transmission means (21) is received for transmitting electrical energy and/or data between at least one frame-side energy source (22) and a door leaf-side energy receiver. (23) serves,and with a gearbox (G) to provide length compensation for the transmission means (21) during movement of the sliding element (11) along the guide section (1). According to the invention, a mounting unit (M) is provided for attaching the guide rail (100) to the door leaf (101) or to the door frame (102) with a DIN left stop (L) or a DIN right stop (R) on a hinge side (In) or on a hinge-side side (Out) of the door leaf (101) or the door frame (102).
