Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a fixed base is used to hold the projection optical apparatus, optical path changer, and light modulator, then the structural stability is improved, but the apparatus size increases
Solution Approach 1:
The patent merges the support functions for the projection optical apparatus, optical path changer, and light modulator into a single integrated holder structure. This holder combines multiple support features that were previously distributed across separate mounting components, achieving both structural stability and compactness by eliminating redundant support elements.
Solution Approach 2:
The holder is designed as a multi-functional component that simultaneously supports the projection optical apparatus, optical path changer, and light modulator. This universal support structure replaces multiple separate mounting mechanisms, reducing the overall apparatus volume while maintaining the stability needed for precise optical alignment and operation.
2Manufacturing precision
If multiple separate holders are used for different optical components, then the positioning precision is improved, but the device complexity increases
Solution Approach 1:
The integrated holder is segmented into distinct support regions for the projection optical apparatus, optical path changer, and light modulator. Each region provides precise positioning for its respective component while being part of a unified structure, avoiding the complexity of multiple separate holders while maintaining manufacturing precision.
Solution Approach 2:
Multiple positioning functions that were previously distributed across separate holders are merged into a single integrated holder design. This consolidation maintains the precise positioning capability for each optical component while simplifying the overall device structure and reducing assembly complexity.

AI summary
A projector according to an aspect of the present disclosure includes a light source apparatus, an image generator, an optical path changer, and a projection optical apparatus. The image generator includes a light modulator that modulates the light emitted from the light source apparatus in accordance with image information to generate the image light, and a first holder that holds the light modulator. The optical path changer includes an optical part that the image light outputted from the image generator enters, an optical support section that pivotably supports the optical part, and a second holder that holds the optical support section. The projection optical apparatus includes a projection system that the light emitted from the optical path changer enters, and a third holder that holds the projection system. The first and second holders are fixed to the third holder.
