Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional projecting lamps primarily focus on diversifying patterns without integrating audio functionality, limiting their practicality and user experience.
Innovation Solution
A pattern projecting apparatus that includes a light-emitting assembly, a film assembly with a galactic starry sky pattern, an audio assembly with an identifying module and speaker, and an imaging assembly, which automatically identifies electronic labels on the film sheets to play corresponding audio, enhancing user experience by combining projected patterns with audio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a projecting lamp focuses on diversifying patterns, then the variety of projected images is improved, but the functional single-mindedness worsens
Solution Approach 1:
The projecting lamp is designed to perform multiple functions: it can project diverse patterns through interchangeable film sheets and simultaneously play corresponding audio content. The control board integrates both image projection control and audio playback control, making the device universal in its capabilities rather than single-functioned
2Ease of operation
If an identifying module and audio assembly are added to the projecting lamp, then the user experience is improved, but the device complexity increases
Solution Approach 1:
The identifying module and audio assembly are merged into the existing projecting lamp structure. The control board serves dual purposes: controlling the light-emitting assembly for pattern projection and controlling the speaker for audio playback. This merging approach improves user experience while minimizing the increase in device complexity
3Extent of automation
If film sheets with electronic labels are used for automatic identification, then the automation level is improved, but the manufacturing complexity increases
Solution Approach 1:
Instead of embedding complex identification hardware in each film sheet, the patent uses electronic labels that store identification information. The control board reads this information and automatically identifies the corresponding audio content. This copying approach achieves automatic identification while keeping the film sheet manufacturing relatively simple
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to change film sheets and hear associated audio, improving the practicality and user experience of the projecting apparatus by integrating audio with pattern projection.
Implementation Method 1
the light-emitting assembly includes at least one first incoherent light source and at least one first condensing lens, and the first condensing lens is arranged on an illuminating surface of the first incoherent light source
Implementation Method 2
an imaging assembly arranged in the first housing and including at least one lens, the lens is arranged on the other side of the film sheet relative to the first condensing lens
Data Source
AI summary
The utility model discloses a pattern projecting apparatus for automatically identifying and playing an audio. The projecting apparatus includes a first housing, a light-emitting assembly, a film assembly, an audio assembly, and an imaging assembly. The audio assembly includes a control board, an electronic label corresponding to a film sheet, an identifying module for identifying the electronic label and arranged on the control board, a storage medium pre-stored with an audio corresponding to a galactic starry sky pattern, and a speaker electrically connected to the control board. The electronic label is arranged on the film assembly. When the film assembly is mounted in a first mounting hole, the identifying module identifies the electronic label on the film sheet, positions the audio corresponding to the electronic label in the storage medium and plays the audio via the speaker, so that the galactic starry sky pattern projected by the projecting apparatus is played in combination with the audio. A user can hear an audio corresponding to a pattern of the film sheet when changing different film sheets. Therefore, the user's experience is effectively improved, and the practicability of the projecting apparatus is enhanced.
