Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lamps have limited light illumination areas that are difficult to adjust, requiring cumbersome movements and lack height adjustment, making them inconvenient for use in various settings.
Innovation Solution
A lamp design featuring a light source mounted on a ball and socket joint for easy directional adjustment and a height adjustable controller, allowing for flexible positioning and stability with a spring mechanism to secure the light source's angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the light source is mounted on a fixed position, then the lamp structure is simple, but the light illumination area cannot be adjusted and user needs to move the entire lamp which is difficult and inconvenient
Solution Approach 1:
The patent applies a ball and socket joint mechanism that enables dynamic adjustment of the light source position and angle. The steering ball rotates within the first through hole, allowing the light illumination area to be adjusted by rotating the steering ball, while the spring provides restoring force to maintain stable positioning. This dynamic mechanism resolves the contradiction by enabling easy adjustment without moving the entire lamp.
2Ease of operation
If the light source is mounted on a ball and socket joint for easy adjustment, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The ball and socket joint is segmented into functional components: the steering ball for rotation, the first through hole for guidance, and the spring for positioning. This segmentation allows each component to perform its specific function simply, resolving the contradiction by making the complex adjustment mechanism easier to manufacture and maintain while preserving ease of operation.
3Adaptability or versatility
If the controller is mounted outside the lamp, then the lamp structure is simple, but the height adjustment function is missing and operation becomes troublesome
Solution Approach 1:
The controller is merged with the lamp body by mounting it on the base, integrating the height adjustment function into the overall lamp structure. This allows the controller to adjust the height of the light source relative to the base, providing adaptability for different usage scenarios without requiring a completely separate control mechanism.
4Stability of the object's composition
If the spring force is increased to improve positioning stability, then the stability is improved, but the ease of rotation deteriorates
Solution Approach 1:
The spring parameters (force constant, pre-compression) are optimized to provide sufficient positioning stability while maintaining smooth rotation. The spring force is calibrated to hold the steering ball at the desired position without creating excessive friction, resolving the contradiction by finding the optimal parameter range that balances stability and ease of rotation.
