Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The mounting of supply lines in aircrafts is cumbersome and time-consuming due to the need for precise positioning and varying distances from structural parts.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple discrete spacer parts are used to achieve various predetermined distances, then the required distance precision is improved, but the device complexity and assembly time increase
Solution Approach 1:
The spacer is designed as an extendable structure with telescopic segments that can be adjusted to different lengths. The segments can slide relative to each other along guide surfaces and be locked at predetermined positions using locking elements, allowing a single spacer to provide multiple discrete distance settings instead of requiring multiple separate spacer parts.
Solution Approach 2:
A single extendable spacer component performs the function of multiple discrete spacers by providing adjustable length through its telescopic mechanism. The spacer can be set to various predetermined lengths depending on the mounting requirements, making it a universal solution that replaces multiple specialized spacer parts.
2Manufacturing precision
If multiple discrete spacer parts are preassembled for various distances, then the mounting accuracy is improved, but the time consumption and material usage increase
Solution Approach 1:
The extendable spacer allows operators to adjust the distance setting on-site by extending or retracting the telescopic segments to the required predetermined length, eliminating the need to preassemble multiple discrete spacer parts and select the correct one during installation.
Solution Approach 2:
The spacer includes predetermined locking positions that are pre-configured at specific distances from the mounting surface. These pre-configured positions allow for accurate mounting without requiring complex preassembly procedures, as the locking elements automatically engage at the correct predetermined lengths.
3Device complexity
If a fixed-length spacer is used, then the device complexity is reduced, but the adaptability to different mounting distances decreases
Solution Approach 1:
The spacer transitions from a fixed-length design to a dynamic extendable design with telescopic segments that can be adjusted to different lengths. The segments slide along guide surfaces and can be locked at various predetermined positions, providing adaptability while maintaining structural simplicity through the use of straightforward mechanical components.
Solution Approach 2:
The spacer is divided into multiple telescopic segments that can extend and retract relative to each other. This segmentation allows the spacer to achieve variable lengths while keeping each individual segment structurally simple, resolving the contradiction between complexity and adaptability.

AI summary
The present invention relates to an extendable holding device. In order to provide for a simpler, easier, more reliable, more accurate and less time- and material consuming way in mounting supply lines in predetermined distances, the holding device comprises a supply line holding unit (12), a fastener (14) and an adaptable spacer (16). The supply line holding unit comprises an at least partly enclosed holding opening (18) for holding a supply line. The fastener is configured to mount the supply line holding unit to a support structure (20). The adaptable spacer is configured to be arranged between the supply line holding unit and the support structure to which the holding device is to be mounted. The adaptable spacer is extendable in a longitudinal direction of the fastener and is temporarily lockable at least at a first and a second predetermined length (24, 26).
