Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light emitter is added to illuminate the operation target, then illuminability is improved, but device complexity increases
Solution Approach 1:
The patent combines the light emitter and optical member into an integrated illumination system attached to the electric work machine. The optical member is positioned to work in conjunction with the light emitter, creating a unified structure that provides illumination without requiring separate independent components, thus improving illuminability while controlling device complexity.
Solution Approach 2:
The illumination system is designed as a multi-functional attachment that can be applied to various electric work machines. The optical member serves both as a light guide and as a structural component that can be integrated with different machine types, making the solution universally applicable across multiple device platforms.
2Stability of the object's composition
If an optical member with light guide is used to distribute light, then uniformity of illumination is improved, but device complexity increases
Solution Approach 1:
The optical member is designed with specific local optical properties - the light guide portion has refractive characteristics that differ from other portions of the structure. This local differentiation in optical quality allows uniform light distribution through total internal reflection in specific zones while maintaining structural simplicity overall.
Solution Approach 2:
The patent utilizes optical path dimensioning by creating a light guide that extends light trajectories through the optical member. By manipulating the dimensional path of light rays through refraction and reflection surfaces, uniform illumination is achieved across the target area without requiring complex multi-component assemblies.

AI summary
An intended illumination area is illuminated with light. An electric work machine includes a motor including a rotor rotatable about a rotation axis extending in a front-rear direction, an output unit located frontward from the motor and operable under a rotational force from the rotor, a light emitter, and an optical member including at least one light receiver that receives light from the light emitter and a light guide surrounding at least a part of the output unit to allow light from the at least one light receiver to travel through the light guide. The light guide has a rear surface having at least one slit, and a front surface to allow emission of light traveling through the light guide and reflected at the at least one slit.
