Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-held spotlights with fixedly mounted power supplies are inconvenient for mounting and incompatible with mobile power packs, leading to structural inefficiencies and usability issues.
Innovation Solution
A hand-held spotlight design featuring a detachable power supply box with clamping blocks, a movable switch base, and a cover body that automatically clamps the power supply box, allowing for easy detachment and mounting, along with a USB interface for external power supply and protection against moisture, and a lifting handle for enhanced usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the power supply is fixedly mounted on the housing, then the structure is stable, but it is inconvenient for mounting and inapplicable to a mobile power pack
Solution Approach 1:
The power supply is divided into a detachable power supply box that can be separated from the housing. The housing includes a mounting base with an accommodating cavity, while the power supply box can be independently removed and replaced, enabling use with mobile power packs and simplifying mounting operations.
Solution Approach 2:
The power supply mounting structure transitions from a fixed state to a dynamic state where the power supply box can be easily inserted and removed. The clamping mechanism allows the power supply box to be securely held when mounted but freely detachable when needed, providing operational flexibility.
2Ease of operation
If the power supply is fixedly mounted on the housing, then the structural stability is maintained, but the mounting convenience is reduced
Solution Approach 1:
The clamping blocks are pre-positioned on the housing and power supply box respectively. When the power supply box is inserted into the accommodating cavity, the clamping blocks automatically engage to secure the power supply box in place, providing both ease of mounting and structural stability without requiring additional fastening operations.
3Ease of operation
If the cover body is hinged to allow opening, then accessibility to power supply is improved, but the risk of accidental flipping increases
Solution Approach 1:
The clamping blocks on the cover body and housing automatically engage when the cover body is closed, creating a self-locking mechanism that prevents accidental opening or flipping without requiring additional latches or fasteners. The geometry of the clamping blocks ensures they engage naturally upon closure.
4Ease of operation
If the switch base is movable to enable power switching, then the ease of power control is improved, but the structural complexity increases
Solution Approach 1:
The power switching function is merged with the cover body closure action. When the cover body is closed and the clamping blocks engage, the switch base is automatically actuated to turn on the power. This combines the mechanical action of closing the cover with the electrical switching function, eliminating the need for a separate switch mechanism.
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
The design enables convenient power supply management, automatic power switching, protection against moisture, and universal handling, improving the compactness and usability of the spotlight.
Implementation Method 1
The mounting cavity is internally provided with a reset spring, both ends of which are respectively in abutment with the switch base and the mounting base

AI summary
A hand-held spotlight, having: a housing provided with an accommodating cavity; a power supply box detachably disposed in the accommodating cavity; a switch base connected to the housing and provided with a first clamping block; and a cover body hinged with the housing, wherein the cover body is capable of covering an opening of the accommodating cavity to confine the power supply box within the accommodating cavity, and the cover body is provided with a second clamping block, which is clamped with the first clamping block when the cover body covers the opening of the accommodating cavity, thereby restricting the flipping of the cover body.
