Light-Emitting Wall Clock With Integrated Housing and Light Guide Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light emitting wall clocks have high manufacturing costs due to numerous components, leading to high selling prices that deter consumers from purchasing them.
Innovation Solution
The design integrates the upper frame, washer, and chassis into a housing seat, and combines the glass lens and light guide lens into a light guide cover, reducing components and simplifying assembly, thereby lowering production and assembly costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the conventional light emitting wall clock includes numerous components such as upper frame, glass lens, clock dial, light guide lens, chassis, light stripe and light sensor, then the clock can sense changes in ambient light and light up the clock dial, but the manufacturing costs, material costs, production time and selling price increase significantly
Solution Approach 1:
The patent combines multiple components into integrated structures: the housing integrates the upper frame, chassis and light sensor; the light guide cover integrates the glass lens and light guide lens; the back cover integrates the light stripe. This merging reduces the total component count from 7 separate parts to 4 integrated parts, directly addressing the technical contradiction by maintaining functionality while reducing complexity.
Solution Approach 2:
The housing serves multiple functions simultaneously: it provides structural support (replacing upper frame and chassis), houses the light sensor, and forms part of the clock's exterior. The light guide cover simultaneously serves as a protective cover, a light guide element, and a lens component. This multi-functionality allows the clock to maintain its light sensing and illumination capabilities with fewer components.
2Reliability
If the conventional light emitting wall clock includes numerous components, then the clock can perform light sensing and illumination, but the subsequent assembly steps become complex and time-consuming
Solution Approach 1:
By merging multiple components into integrated parts (housing combining frame/chassis/sensor, light guide cover combining lens elements, back cover combining light stripe), the number of assembly steps is reduced. Fewer separate components mean fewer connection operations, directly improving assembly efficiency while preserving the clock's functional reliability.
3Manufacturing precision
If the conventional light emitting wall clock includes numerous components requiring separate molds, then the manufacturing precision can be maintained, but the manufacturing costs and material costs increase
Solution Approach 1:
The patent integrates multiple components into fewer molded parts: the housing combines the upper frame, chassis and light sensor housing into one molded piece; the light guide cover combines the glass lens and light guide lens into one molded component; the back cover combines the light stripe structure into one molded part. This reduces the number of molds required from 7 to 4, directly reducing manufacturing costs and material costs while maintaining manufacturing precision through integrated molding.
