Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional fixing means such as screws, clamps or adhesive are employed to secure the support board, then the fixation reliability is improved, but the device complexity and manufacturing costs increase
Solution Approach 1:
The support board integrates spring elements directly into its structure, merging the fixation function with the support board itself. This eliminates the need for separate fixing means like screws or clamps, thereby maintaining reliable fixation while reducing device complexity and manufacturing costs.
Solution Approach 2:
The spring elements on the support board provide self-fixing capability by elastically engaging with the supporting profile. The support board automatically secures itself within the profile through the elastic force of the spring elements, eliminating the need for additional fixing components and simplifying the overall device structure.
2Adaptability or versatility
If the aircraft light is designed to be compact to fit into confined spaces, then the adaptability is improved, but the heat dissipation efficiency deteriorates
Solution Approach 1:
The spring elements are strategically positioned at specific locations on the support board to create localized thermal conduction paths. This allows heat to be efficiently dissipated from critical areas of the support board to the supporting profile, maintaining heat dissipation efficiency while preserving the compact overall design for adaptability to confined spaces.
3Ease of manufacture
If spring elements are integrated into the support board for easy assembly, then the ease of manufacture is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The spring elements are designed with specific geometric parameters and material properties that provide elastic compliance. This allows the spring elements to accommodate minor dimensional variations and misalignments during assembly, reducing the impact of manufacturing precision limitations while maintaining ease of assembly and integration into the support board.

AI summary
An aircraft light (2) comprises a support board (4) and a supporting profile (10). The support board (4) supports at least one electric light source (6), in particular at least one LED. The support board (4) has two lateral edges (5a, 5b), which extend in a longitudinal direction of the support board (4) and which are spaced apart from each other in a transverse direction (T) of the support board (4). The supporting profile (10) comprises a receiving space (12) for receiving and supporting the support board (4). The receiving space (12) is defined by a base (14), extending in a longitudinal direction (L) of the supporting profile (10) and in a transverse direction (T) of the supporting profile (10), and two opposing side walls (16a, 16b) protruding from the base (14). The supporting profile (10) further comprises two undercut sections (20a, 20b), forming opposing slots in the two opposing side walls (16a, 16b) that are dimensioned for accommodating a lateral edge (5a, 5b) of the support board (4), respectively. At least one of the two lateral edges (5a, 5b) of the support board (4) comprises at least one spring element (9) for elastically fixing the support board (4) within the receiving space (12), with the two lateral edges (5a, 5b) of the support board (4) being arranged in opposing slots.
