Spark Plug Holder With Rotation Guide Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing airplane spark plug tray devices fail to depict the physical orientation of engine cylinders and the correct rotation sequence, making it difficult for users to properly rotate and reinstall spark plugs without prior knowledge.
Innovation Solution
A spark plug holder tray with openings for each plug, featuring raised text for cylinder numbering, orientation, and guide lines to visually guide the rotation sequence, ensuring correct reinstallation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If existing spark plug tray devices are used, then spark plugs can be held and organized, but the physical orientation of cylinders and rotation sequence information is not provided
Solution Approach 1:
The device pre-markes cylinder numbers, orientation indicators (T/B labels), and rotation sequence guide lines on the tray before use. This preliminary provision of information eliminates the need for users to have prior knowledge of cylinder orientation or rotation sequences, directly resolving the information loss problem while maintaining ease of operation.
Solution Approach 2:
The tray acts as an intermediary device between the spark plugs and the engine cylinders. By incorporating visual guides (cylinder numbers, orientation markers, and rotation sequence lines) on the tray itself, it mediates the complex task of spark plug rotation, making the process intuitive and eliminating the need for users to memorize or understand engine-specific orientation and rotation sequences.
2Ease of operation
If users rely on existing spark plug trays, then simple storage is achieved, but prior knowledge of cylinder orientation and rotation order is required
Solution Approach 1:
The spark plug tray is designed to be self-instructive, with all necessary information (cylinder numbers, T/B orientation labels, and rotation sequence guide lines) directly marked on the device. The tray serves itself by providing the information users would otherwise need to obtain from external sources or prior knowledge, thereby improving ease of operation without sacrificing information completeness.
3Duration of action of moving object
If spark plugs are not properly rotated according to correct sequence, then installation time is reduced, but spark plug life is shortened
Solution Approach 1:
The rotation sequence guide lines are pre-marked on the tray, showing the correct rotation path from one cylinder to the next. This preliminary visual guidance ensures that users can quickly and correctly rotate spark plugs without needing to study rotation sequences or spend time determining the correct order, thereby extending spark plug life without increasing time loss.

AI summary
A device for holding and guiding rotation of aircraft spark plugs is herein disclosed. The device includes a main body, openings defined in the main body, characters of text disposed on a top surface of the main body, and guide lines. Each opening is sized to receive one of the spark plugs. Each character of text is positioned adjacent a respective opening of the openings. Further, each guide line runs from one opening to another opening to serve as a guide for rotating the spark plugs.
