Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an elastic body is used for the adjustment mechanism to enable position adjustment, then the adjustment operation becomes easier, but the stability and accuracy of the adjusted state deteriorates due to play in components
Solution Approach 1:
The positioning mechanism is divided into three independent adjustment mechanisms (first for axial position, second for lateral position, third for inclination), each responsible for a specific degree of freedom. This segmentation allows each mechanism to be optimized independently - the elastic body provides ease of operation for its specific adjustment while the fixating member ensures stability when fixed, resolving the contradiction between operational ease and positioning accuracy.
2Stability of the object's composition
If fixating members are used to ensure stability of the adjusted state, then the stability improves, but the adjustment operation becomes more difficult due to additional components and steps
Solution Approach 1:
The fixating function is segmented into three independent fixating members corresponding to each adjustment mechanism. Each fixating member can be operated independently to lock its corresponding adjustment mechanism, allowing stable fixation without requiring complex interaction between components. This maintains ease of operation while ensuring stability.
Solution Approach 2:
Each adjustment mechanism includes its own integrated fixating member that serves both the adjustment and fixation functions for that specific degree of freedom. The mechanism is self-contained and self-sufficient, eliminating the need for additional separate fixating components and simplifying the overall adjustment operation.
3Ease of manufacture
If simple adjustment mechanisms are used to reduce device complexity, then the ease of manufacture improves, but the ability to adjust inclination and achieve highly accurate positioning deteriorates
Solution Approach 1:
The complex task of three-dimensional positioning and inclination adjustment is segmented into three independent one-degree-of-freedom adjustment mechanisms. Each mechanism uses simple components (elastic bodies and fixating members) that are easy to manufacture, while collectively achieving high positioning accuracy through their coordinated action.
Solution Approach 2:
Three simple adjustment mechanisms are merged into a unified positioning system that collectively achieves complex positioning and inclination adjustment. Each mechanism contributes one aspect of the positioning function, and their combination provides comprehensive high-accuracy positioning capability while maintaining simplicity in individual components.

AI summary
A light source apparatus includes a light source, an optical fiber, and a positioning mechanism. The positioning mechanism is configured with a planar position adjustment mechanism, an axial line position adjustment mechanism, and an orientation maintaining mechanism. The planar position adjustment mechanism adjusts a position of the optical fiber in a direction following the light-emitting surface. The axial line position adjustment mechanism adjusts the position of the optical fiber in a direction intersecting with the light-emitting surface. The orientation maintaining mechanism holds the optical fiber in a state where an axis direction of the optical fiber lies in a predetermined intersecting direction with respect to the light-emitting surface.
