Rotating Multi-Output Device Frame for Shadow-Free Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical apparatuses for converting electric power to light, wind, heat, or sound are difficult to make compact, lightweight, and durable while incorporating self-standing and rotational mechanisms, and often suffer from obstacles when carried and shadows when projecting light due to guard members.
Innovation Solution
The design includes a main body portion with a converting portion that outputs light, wind, or heat, a battery pack detachably mounted on a holder, and a frame portion that rotatably supports the main body, allowing it to stand independently and rotate, with a guard region protecting the battery pack and a hook for tube pipe attachment, and a cover member that avoids shadow formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a frame portion with guard member is added to protect the projection surface, then durability is improved, but shadow formation occurs when light is projected
Solution Approach 1:
The guard member is extracted from the frame portion and repositioned to the rear side of the main body, separating its protective function from the light projection path. This allows the projection surface to remain unobstructed while the guard member continues to provide durability protection.
Solution Approach 2:
The guard member is moved from the front dimension (in the light path) to the rear dimension (behind the main body), changing its spatial position to eliminate shadow formation while maintaining its protective function against impacts from behind.
2Adaptability or versatility
If a hook is provided at the handle for tube pipe attachment, then adaptability is improved, but the hook becomes an obstacle to the handler
Solution Approach 1:
The hook is extracted from the handle and repositioned to the frame portion, separating its attachment function from the handle. This allows the handle to remain clear and comfortable for carrying while the hook provides tube pipe attachment capability at its new location.
Solution Approach 2:
The hook is moved from the handle dimension to the frame portion dimension, changing its spatial location to eliminate interference with handling while maintaining its adaptability for tube pipe attachment.
3Weight of moving object
If the electrical apparatus is made compact and lightweight, then ease of handling is improved, but durability for enduring impacts is reduced
Solution Approach 1:
The frame portion with guard member is designed to absorb and cushion impacts before they reach the main body and battery pack. This protective structure is built in advance to endure drops and impacts, protecting the compact lightweight apparatus without adding excessive weight.
Solution Approach 2:
The frame portion is constructed from materials that provide high strength-to-weight ratio, combining durability for impact resistance with lightweight properties. This allows the apparatus to maintain compact size and low weight while enduring impacts from drops.

AI summary
This invention provides an electrical apparatus (1) that includes a main body portion (10), a battery pack (15), and a frame portion (20). The main body portion (10) comprises a converting portion (2) that may convert electric power to one of light, wind, heat, and sound; and an outputting portion (12). The battery pack (15) may detachably mounted on a battery holder (14) provided at the main body portion (10), and may supply electric power to the converting portion (2). The frame portion (20) may rotatably support the main body portion (10), and may define a first ground contact plane that can contact a ground surface and a second ground contact plane that can contact the ground surface at a different angle from an angle of the first ground contact plane. The main body portion (10) may be rotatable relative to the frame portion (20) without contacting the ground surface.
