Interactive Exercise Mirror with Posture-Adaptive Position Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional smart mirrors for fitness exercises are not adjustable in height or angle, making it difficult for users to see their entire body while performing exercises such as sit-ups or lying down, as the mirror's fixed position and angle do not accommodate varying user postures.
Innovation Solution
A smart mirror system with a movable frame and display device, equipped with a determination unit and driving mechanism that automatically adjusts the mirror's angle and height based on user location and posture, using image recognition or sensors to ensure the user can see their reflection and guiding images effectively during exercises.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the smart mirror is fixed on the wall or leaned against the wall at a fixed angle and position, then the mirror structure is simple and stable, but the user cannot see their entire body when performing exercises such as sit-ups or lying down
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed mirror structure into a movable one. The mirror is equipped with a driving mechanism that can automatically adjust its position and angle based on the user's posture. This allows the mirror to adapt dynamically to different exercise positions (standing, sitting, lying down) while maintaining a relatively simple overall structure through automated control.
Solution Approach 2:
The patent implements self-service by enabling the mirror to automatically adjust its own position without manual intervention. The determination unit detects the user's posture, and the control unit automatically commands the driving mechanism to reposition the mirror accordingly. This self-adjusting capability resolves the contradiction by providing adaptability through automation rather than complex manual adjustment mechanisms.
2Adaptability or versatility
If the smart mirror is fixed at a specific height and angle, then the manufacturing and installation are simple, but the mirror cannot accommodate varying user postures during different exercises
Solution Approach 1:
The patent applies universality by designing the mirror as a multi-functional device that can serve multiple exercise postures. The driving mechanism enables the mirror to perform multiple functions (adjusting to standing, sitting, lying positions) while maintaining a unified structure. This resolves the contradiction by achieving posture accommodation through a single automated system rather than multiple fixed mirrors for different exercises.
Solution Approach 2:
The patent implements parameter changes by allowing the mirror's position parameters (height, angle, horizontal position) to vary automatically based on detection results. The control unit adjusts these parameters dynamically according to the user's posture, enabling the mirror to accommodate different exercises without requiring multiple fixed installations or complex manual adjustments.
3Reliability
If the smart mirror is mounted at a fixed position, then the installation is simple and stable, but the user cannot maintain proper visibility of their body during various exercises
Solution Approach 1:
The patent applies feedback by creating a closed-loop control system. The determination unit continuously detects the user's posture, and this information is fed back to the control unit, which then adjusts the mirror position accordingly. This feedback mechanism ensures reliable visibility during various exercises while maintaining moderate automation through automated detection and adjustment based on real-time posture information.
Solution Approach 2:
The patent replaces manual mechanical adjustment with automated detection and control systems. Instead of requiring manual mirror repositioning, the system uses sensors to detect posture and automatically commands the driving mechanism to adjust the mirror. This substitution achieves reliable visibility through automation while keeping the overall system relatively simple through integrated control.

AI summary
An interactive exercise apparatus for guiding a user to perform exercises includes a frame, a mirror, a display device, a driving mechanism, a determination unit, and a control unit. The mirror is movably mounted on the frame and configured to reflect an image of the user. The display device is disposed on a backside of the mirror and visible through the mirror. The driving mechanism is mounted between the frame and the mirror for electrically driving the mirror to move with respect to the frame. The determination unit is configured to determine location or posture of the user who performing the exercise. The control unit is operable to control the driving mechanism according to the location or posture of the user identified by the determination unit so as to control the mirror to move to a suitable position where the user can see their reflected image.
