Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional holographic display devices use complex light sources and optical systems to achieve effective hologram illumination, then holographic image quality is improved, but device size and weight increase making them bulky and difficult to transport
Solution Approach 1:
The patent combines the light source, optical diffuser, and hologram holder into a single integrated penlight device. The light source is positioned directly within the penlight body, eliminating the need for separate illumination equipment. This merging of components achieves effective hologram illumination while maintaining portability and reducing overall device weight.
Solution Approach 2:
The patent extracts and eliminates unnecessary complex optical systems from conventional holographic display devices. By using a simplified light source configuration with an optical diffuser, the design removes bulky components while maintaining the essential function of illuminating the hologram effectively.
2Reliability
If conventional holographic display devices use complex optical systems to constrain relative positions of hologram, light source and viewer, then holographic image legibility is improved, but device complexity increases
Solution Approach 1:
The patent applies local quality by positioning the optical diffuser at a specific location within the penlight body to create the necessary light angle for hologram illumination. Instead of using complex optical systems throughout the entire device, the diffuser is placed only where needed to achieve the proper light distribution and holographic image quality.
Solution Approach 2:
The penlight device is designed so that the light source automatically illuminates the hologram at the correct angle when the device is held in the proper orientation. The optical diffuser self-adjusts the light path without requiring complex mechanical constraints or adjustment mechanisms, simplifying the overall system while maintaining image legibility.
3Weight of moving object
If existing penlights and flashlights are designed for general illumination, then portability is maintained, but they cannot provide effective hologram illumination or decorative functions
Solution Approach 1:
The patent creates a universal penlight device that combines multiple functions: general illumination, hologram viewing, and decorative lighting. The same light source and optical diffuser configuration can illuminate holograms effectively while also providing decorative lighting effects, making the device adaptable to multiple purposes without sacrificing portability.
Solution Approach 2:
The patent incorporates a rotatable component that allows the user to dynamically change the orientation of the light source relative to the hologram. This dynamic adjustment capability enables the same device to serve different functions - illuminating holograms when oriented one way and providing decorative effects when oriented another way, thereby increasing functional versatility.

AI summary
[Problem] A penlight used for decoration or as a flashlight for the purpose of illuminating the surroundings lacks functionality for optimal enjoyment of a hologram, and no conventional illumination device for a hologram has decorative effect. [Solution] The present invention has a hologram support unit, a light source, and a light diffuser, and by primarily irradiating the light diffuser from the light source, decorative effect is increased, and primarily a hologram image region can be illuminated from a predetermined angle from the same light source or a different light source. Appropriate observation is made possible by making note to an observer on a portion of a medium material integrated with a hologram material whether to irradiate illuminating light from above or irradiate illuminating light from below.
